Road hub review, 28 hubs

Postby madcow » Wed Feb 10, 2010 1:13 am

Recently I had posted some quick thoughts on the differences between the most popular hubs. That led to a few requests for some more thoughts on the subject. Well I figured I'd take a more in depth approach to it and try to post a wide range of spec's and thoughts. Not only my own thoughts, but for the first time I'll do a joint review. I've chosen to do it with a very skilled builder that I have a lot of respect for, Ron Ruff of White Mountain Wheels

The specs of course were compiled by us here at Fair Wheel and Ron at White Mountain Wheels, and while we did do our best to be careful there were an awful lot of numbers and calculations thrown around over those days. So with that in mind I'd like to put out the disclaimer that it isn't impossible that we might have transcribed, written or recorded a number incorrectly. So please forgive any typos or mistakes. We've already corrected a ton and now like to think that most things should be correct, but with the scale of this thing it's still likely that one will find a mistake.

We've got 28 hubs from the following companies: Alchemy, C4, Chris King, DT, Extralite, Ligero, M5, Soul-Kozak, Tune and White Industries.

As we've been building this over the last 2 weeks this thing has started to really grow in size. So much so that it had to be broken up into 3 parts each as a reply in this thread. Part 1 is front hubs, part 2 is rear hubs, part 3 are charts, calculators etc... You may find that when you get to the 2nd reply(3rd total post) you may have to hit your refresh button to get the spreadsheets to appear. We've attached some live, sortable google spreadsheets to the end with much of the pertinent information to make it easy to sort according to any property that you desire. These spreadsheets combined with all the text and pictures of the post seem to overload the forum a bit. So if you end up with anything missing, a quick refresh should take care of it.

The format of the review will be as follows.

Summary and thoughts by yours truly: My thoughts will be completely random and contain almost no structure. Sorry about that, but I think it's a result of a massive amount of hours spent staring at a screen.

Summary and thoughts by Ron:
--------------------------------
*Variable specs are all based on a wheel using a Kinlin XR300 rim laced 2x.

Before we start the actual review, we wanted to cover a few aspects of the review. Manufacturer, Model and Weight need no explanation.

Available drillings: this is what is currently available, I know some hubs such as Ligero have future versions planned with other drillings.

Bearing material: this is what comes stock in the base model. Some hubs have upgrades available from the factory.

Bearing size: moving from left to right in the hub shell and then in the hub body.

Static load: for each bearing individually. Static load rating is the maximum amount of load a bearing can take without excessive deformation that would degrade the bearing performance.

Notes on Bearings and drag: Since ceramic bearings became the rage a few years ago, bearing drag has been a hot topic among cyclists. Unfortunately, there doesn't seem to be much public information on just how much of a loss the wheel bearing drag contributes. According to Bicycle Science the drag of clean, lubricated, properly aligned and adjusted ball bearings is very small. The friction coefficient is ~.0015... which is the ratio of resistive force generated in the bearing divided by the load it is carrying. If you are familiar with tire rolling resistance coefficients, this functions in the same way... except that you need to multiply this force by the bearing/wheel radius to get a comparable factor. So lets say we have a hub with 15mm axle, and the bearings are on a radius of ~12mm. The wheel's radius is ~335mm, so 12/335 *.0015 gives us an equivalent rolling resistance coefficient of .000054. To give you an idea of how small this is, typical tire rolling resistance coefficient is about .005... so the bearing resistance is ~100 times smaller. Another way to look at it is that a 200lb rider+bike traveling at 25mph will lose ~0.5W from the bearing rolling resistance. And these are not fancy bearings we are talking about... just decent steel ones.

There is another major component to bearing drag though, and that is the resistance of the seals. John Swanson did some interesting coast-down tests of wheels shown here: http://www.bikephysics.com/rails/wheel/list Aerodynamic drag was part of it, but his instrumentation was sophisticated enough to back out the bearing drag alone. Ron did the calculations on the bearing coefficients he obtained, and got an average power consumption of 0.25W for front hubs and 0.40W for the rear hubs at 25mph... or 0.65W for both wheels. Note that there was a lot of variation, but even the worst set of wheels was only ~1.3W. Since the only load in his tests was the weight of the wheel we'd consider these values additive to the 0.5W determined above... so typical losses are about 1.2W total. Though the losses in this test would capture any effects of misalignment or preload in the unloaded state, we should point out that under typical loads these factors can result in additional friction.

Does this mean that bearings don't matter? We wouldn't say that. Instead we'd emphasize that the most important factors are cleanliness, adequate lubrication, alignment, and adjustment. If any of these are off, then the drag can be much higher. Even though smaller bearings might have lower resistance in an ideal world, larger bearings (higher load rating) will be more tolerant of un-ideal situations, probably resulting in a lower practical resistance in addition to a longer life span. If your typical hub set in good condition is only consuming ~1W then be realistic about how much improvement is possible. The added expense of ceramic bearings and the added hassle of having light seals and grease (which probably will result in quicker bearing contamination and more frequent replacement) may not be worth it.

Axle diameter: Larger axles will typically produce stiffer wheels. It's also important to note that a couple of axles are in different ways, butted or reinforced at the freehub body in the rear to help prevent cantilevering under acceleration.

freehub body material. Almost all hubs in this review use aluminum bodies with the exception of the White Industries.

Available colors: Based on what I know is commonly available, but does not include custom options offered by some.

Price: This is the msrp as it applies in the USA. For imports a current exchange rate of 1.38 was applied.

Flange diameters: Left / Right. As measured by us from center of spoke hole to center of spoke hole. A note or two on flange diameter. The biggest effect of flange diameter comes particularly from the drive side and in the form of torque transfer and a wheels ability to resist windup during acceleration. Typically a larger flange will produce a better result in this category.

Center to flange: As measured by us. It's been noticed that many of our numbers don't match what is claimed by manufacturers. Our measurements are taken by us from center of flange to locknut. Some manufacturers provide outside of flange to center, while others provide numbers for both inside and outside but nothing center. Also some manufacturers may assume a 130 oln when their axle is not exactly 130. We use the actual oln measurement for our calculations. After the flange to center number is calculated it is rounded to 0.5mm.

Bracing angle: Based on a build using Kinlin XR300, 2x. Of course not all of these hubs would be recommended to be laced 2x, and with some it isn't even possible. This was just a way to create an equalizer to show the differences in the hubs on a level playing field. Actual bracing angles and tension differences will vary based on the build. Feel free to find your own numbers using the latest version of Damons spocalc spreadsheet which I will attach to the first reply in this thread. You'll have to save the spreadsheet to your computer before you can use it. Thanks to Eric Gottsman, Troy Watson and Jeremy Parfitt for coming up with the formulas and embedding them into the sheet for triplet.

Notes on Bracing angle: Bracing angle (or flange offset) is the most important factor effecting the lateral stiffness and stability of the wheel. The lateral stiffness imparted by the spokes goes up with the *square* of the bracing angles, while using more or heavier spokes only results in a linear increase in stiffness... and an increase in weight.

On a front wheel it isn't difficult to get adequate offsets and stiffness. The limit is having clearance for the fork, and offsets of up to 40mm are usually fine... the wider the better the lateral stiffness will be. There has been some speculation that narrower spacings are more aerodynamic, but I'd guess this has a tiny effect, if any. I suppose it is also possible that a very flexible rim might experience a lateral wave if the combination of high tension and bracing angle and low spoke count were severe enough, but it isn't an issue I've run into yet.

Bracing presents a conundrum on the rear wheel though, since the position of the DS flange is dictated by the 130mm dropout spacing, the wide cassette, and providing clearance for the derailleur. Because of this the spacing from the center of the wheel (and rim) is "stuck" being only ~16-19mm from the DS flange with a 130mm dropout width. Campy hubs are generally in the 16-17mm range due to their wider cassettes, and Shimano/SRAM specific hubs *can* be in the 18-19mm range. Yes, Campy hubs are inherently disadvantaged when it comes to making a stiff wheel. You would always like to get the DS offset as great as possible, with the practical limit being a minimal clearance between the spokes and derailleur.

The spacing on the NDS can be whatever the hub manufacturer wants. If it the same as the DS, then both sides will have the same tension... but lateral stiffness and overall stability will be very low. If it is twice as large... say 36mm... the NDS tension will be *half* as great as the DS, but lateral stiffness will be ok. The dilemma here is that a high bracing angle is good for lateral strength and stability, but low tension on the NDS could cause these spokes to go slack when subjected to high radial loads. When spokes go slack the stiffness of the wheel goes way down and bad things can happen... from spokes coming loose due to nipples unwinding, to "taco", wheel failure, etc.

So as you can see, the trick here is to find the best compromise. The hub manufacturers have different ideas about what is best, with the NDS offsets of the conventional hubs in this review ranging from 32.5 to 39mm. The DT's geometry is inherently the least stiff with only ~16mm on the DS and 32.5mm on the NDS. Compare this to the Alchemy hub in S configuration with a DS offset of 19.5mm and NDS offset of 37mm. My back of the envelope calculation gives the Alchemy hub ~25% improvement in lateral wheel stiffness compared to the DT. The Alchemy hub also has a higher tension ratio, so there is no downside. In the DT's favor the freehub is easily swappable between Campy and S without re-dishing, which is why it has a poor DS spacing for an S hub. Other hubs like the Campy versions of the Tune Mag 180, White Industries H3, and Extralite have large NDS offsets, so the stiffness is good... but tension ratios in the 42% range can leave the NDS tension lower than ideal, and is especially troublesome if the rim will not allow high tension on the DS. If the hub allows radial lacing though, lacing the NDS heads-out will improve the tension ratio.

Note that other aspects of hub design can also have substantial effects on wheel stiffness. Axle and shell stiffness, bearing size, tolerance, and arrangement, bearing to axle interface stiffness, and axle to dropout interface stiffness, are all important factors. Unfortunately, quantifying these is beyond the scope of this review.

A note on tools: When we talk about tools we will be talking about special tools. It will be assumed that a bearing puller and press is part of a standard tool kit. For the bearing press, we highly recommend the Wizard from Wheels Manufacturing, but designed by Jeremy from Alchemy. This is truly the most versatile press ever and with details such as an internally threaded shaft it's uses go far beyond being a standard bearing press. We use it to pull axles, install axles, bearings, free hub bodies etc...

Now let's get things started. Since many people mix front and rear hub brands we are going to look at them separately. So, on to the hubs.....
---------------------------------------------

Alchemy Elf
Image

Manufacturer:Alchemy
Model: ELF
Notes: New 2010 version. Radial lacing is allowed.
Weight: 66gr
Available drillings:16/18/20/24/28/32
Bearing material and other bearing notes: Stainless
Bearing size: 6900
Bearing static load: 303
Axle diameter: 12mm
Available colors: Black, Red, Silver
Price in USD: $180
Flange diameters: 32mm
Center to flange: 39mm
Bracing angle: 7.9

Summary: The Elf has to be one of my favorite front hubs. At 66grams it fits nicely into the mid-lightweight hubs. The large bearings static capacity is high, and the flange spacing is the widest of just about anything I've seen. The axle is a nice 12mm, and the bearing placement is about as far outboard as a front hub can tolerate and still have room to clear the fork. That extra bearing width should contribute to an even stiffer front wheel. Combine all of those factors with allowed radial lacing and you have the hub that is likely to produce the laterally stiffest wheel available. Price isn't too high for a hub of such quality. Drilling options are plentiful. If I had one complaint about the hub it would be that it lacked preload adjustment. No preload was a result of having bearings so far to the outside that the axle could not be externally threaded. That however is no longer true. The 2010 version now comes with a rather clever preload adjustment based on internal threading of the axle. Of course the 09 version can be retrofitted with the newest axle kit to upgrade it to the current version. So that doesn't leave much for me to find fault with. I guess the only remaining complaint would be that it's only available in 3 colors. Geez, that really isn't much of a complaint, so let me try again. How about this, there isn't yet a matching sub 200 gram rear option. So if you like your hubs to match you have to either give up some weight, or look for something else. I guess that's not really much of a complaint either. This is the hub that other manufacturers should really be studying and wondering how do they improve on that. Customer service from Alchemy has been absolutely top notch for the few years that we've been dealing with them.

Ron: I really like this hub too. Since the Orc was only recently available I often paired this with the DT240 or 190 rear hub with the sticker peeled off. They look very good together and the Elf saves more than 40g compared to DT... with no downside that I can discern. They have a higher bearing load rating, are super smooth, and the bracing angle is higher, allowing good lateral stiffness even when laced heads-out.

C-4 FH76 and FH78
Image

Manufacturer: C4
Model: FH76 and FH78
Notes: The FH76 and 78 are the same hub with the difference being the in the bearings. Radial lacing is allowed up to 28h.
Weight:FH76: 77gr
Weight:FH78: 79gr
Available drillings: 16/20/24/28
Bearing material and other bearing notes:FH78 uses a stainless Phil wood and the FH78 uses a ceramic hybrid.
Bearing size: 6900.
Bearing static load: 303
Axle diameter: 10mm
Available colors: Black, Silver
Price in USD: FH78: $125
Price in USD: FH76: $135
Flange diameters: 32mm
Center to flange: 32.5mm
Bracing angle: 6.6

Summary: C-4 is a rather new company, but has entered the game with a pretty good splash. The 76/78 is virtually the same hub with the exception of the bearings. While the 76/78 won't build the stiffest wheel in the world, it does have a nice spec, particularly for the price.
It has a large very high quality bearing, and a reasonable mid-lightweight category weight. It's only available in limited colors, black and silver but does come in ample drillings. Like the Elf hub, the C-4 has it's bearings located pretty far to the outside edge of the hub which does help to add some stiffness to the wheel. The 76/78 hub lacks preload adjustment, but still manages to keep play to a minimum. While both the 76 and 78 have high quality bearings, the 76 is very impressive in it's smoothness. I know what the science says about bearing drag and seal drag, but something in me is still impressed every time I spin the hub in my hands, and I just can't help but think it feels fast. This hub has to be really high on the list for anyone with a budget. When you add the UL ti skewers into the package, it's bang for the buck is certainly one of the best. So far customer service has been quite attentive and I'm without complaint about it.

Ron: Not a bad weight at all for an inexpensive hub that has decent sized bearings. With the light Ti QR (similar to KCNC/Far and Near) the price looks even better. The flange spacing is quite narrow, and when I asked them about that they mentioned that clearance for forks that curve inward was the reason. I don't know if that is an issue anyone has run into with wider hubs... I haven't. I'll also attest to great service from C-4... they have that part of the business figured out and I hope they keep it up.
----------------------------------------------

C-4 FH44SP
Image

Manufacturer: C4
Model: FH44SP
Notes: Uses straight pull spokes.
Weight: 42gr
Available drillings: 16/18/20/24
Bearing material and other bearing notes: Ceramic hybrid
Bearing size: 688
Bearing static load: 135
Axle diameter: 8mm
Available colors: Black
Price in USD: $180
Flange diameters: 19.5mm
Center to flange: 37.5mm
Bracing angle: 7.5

Summary: Another offering from C-4 is the 44sp hub. About twice the price of the 78 the 44 has ceramics stock and has a wider bracing angle. The straight pull spokes also offer an increase in durability as the wider spacing will offer a laterally stiffer wheel. Available in only one color, black. The really small bearing makes this a hub that I'd reserve for the light riders or for a race wheel with a middle weight rider. But the wide flange placement, and required radial lacing will make a wheel that's not only light but stiff enough to be deserving of being a race day wheel. While the small bearings don't have much load capacity they should roll with some of the least resistance of just about anything but will also require more often replacement. This hub also does not have any preload adjustment and has a small axle.

Ron: Nothing to add really... except that this might make a good TT hub, with low bearing resistance and a smooth small diameter aspect.

Chris King R45
Image

Manufacturer: Chris King
Model: R45
Notes: Radial lacing allowed.
Weight: 102gr
Available drillings: 20/24/28/32
Bearing material and other bearing notes: Stainless
Bearing size: non standard, 17.5x27x7
Bearing static load: est. 315
Axle diameter: 17mm
Available colors: Black, Blue, Brown, Gold, Green, Orange, Pewter, Pink, Red, Silver
Price in USD: $149
Flange diameters: 40mm
Center to flange: 35mm
Bracing angle: 7.1

Summary: Chris King has long been considered one of the best hubs amongst mountain bikers. Their road hub does not fall short of this reputation either. At 102 grams it's one of the heaviest front hubs in the review, but the weight is reflected in the quality. The made in house angular contact, proprietary bearings have one of the highest load capacities of all tested hubs, they also carry a 5-year warranty. The 17mm axle is the largest of anything in the test. The mid-sized flanges have a nice old school look to them with their cutouts and overall the workmanship is top notch. Surprising to me was that the flange spacing is the narrowest of all the hubs we looked at. Perhaps King feels the bearings and axle compensate for this, or perhaps they just don't feel as though a dish-less wheel needs any more angle. Having such a narrow flange placement may have a slight effect on improving it's aerodynamic properties, but that's still not anything I've seen proven. King has approved these hubs for radial lacing, which is a departure from their other hubs and the make them in drillings down to 20h. The price is quite reasonable for a Chris King product in my opinion. Color choices are more than plentiful, I can't think of anyone that offers more. The preload on the hub is well designed and works as one would expect from such an iconic company, skewers can be clamped at tight as desired without any drag on the bearings. Customer support isn't always the greatest with CK though. Sometimes there seems to be a bit of an attitude that if something failed it's not their fault because they are perfect. It wouldn't be fair to say this attitude is company wide, but depending on the luck of the draw as to who you talk to it can sometimes be hard to get a warranty processed. Availability is also very slim on these right now, but with good reason.

Ron: Should be a solid front hub... but I wish they had figured out a way to pare ~30g from it. It's porky compared to the light rear hub. I haven't used Chris King hubs much in the past because I do a lot more road wheels, but I expect that to change. They have a great reputation with the MTB crowd and I expect these to be very popular with people who want colored hubs. One note on angular bearings is that have inherently higher drag than the ones commonly used... but I can't say if it's enough to worry about.
---------------------------------------------

DT 240
Image

Manufacturer:DT
Model: 240
Notes: Radial lacing version.
Weight: 108gr
Available drillings: 20/24/28/32
Bearing material and other bearing notes: Stainless
Bearing size: 6803
Bearing static load: 276
Axle diameter: 17mm
Available colors: Black (white in 28h)
Price in USD: $180
Flange diameters: 39mm
Center to flange: 37.5mm
Bracing angle: 7.6

Summary: I'm not sure what to say about the DT hub. It's one of those hubs that isn't light, isn't available in many colors and isn't particularly inexpensive. However it is one of those bolt-it and forget-it hubs. I'm told that DT has recently started using a less expensive lower end bearing in their hubs which isn't what I'd like to see in a higher end hub such as DT. The DT hub falls into the middle of just about every category, which makes it a nice hub for a wide range of people, but at the same time doesn't make it a stellar hub for anyone. While it seems I'm having a hard time thinking of good things to say about these I'm also finding it hard to find anything bad. So let's just call it a nice average hub. Customer service has been hit or miss with some good and some bad experiences.

Ron: Decent hub... but it's hefty. Black is the only real choice (unless you want a white 28h). I've had binding issues when lacing it heads-in, but since the flange spacing is fairly wide, heads-out still gives decent stiffness. I rarely use these anymore... even if the customer wants a DT rear hub, I usually convince them to put an Elf on the front.


----------------------------------------------

Extralite SX
Image

Manufacturer: Extralite
Model: Ultrafront SX
Notes: Radial lacing is allowed only heads out.
Weight: 49gr
Available drillings: 16/18/20/24
Bearing material and other bearing notes: Stainless w/ceramic upgrade
Bearing size: 6801
Bearing static load: 188
Axle diameter: 14mm
Available colors: Black
Price in USD: $215
Flange diameters: 28mm
Center to flange: 37mm
Bracing angle: 7.4

Summary: Made in Italy, the new SX hub features a change in the flange, it looses the lip and instead goes for a thicker flange with machining between the spoke holes on the back side of the hub. 49grams makes it certainly one of the lightest hubs out there, but also it's the lightest hub with a preload adjustment. There have been a couple cases of the adjuster having some stripped threads but it seemed to be related to previous versions. I'm told the threads are cut deeper now and it hasn't been a problem since. The bearing is mid sized and rolls incredibly smoothly. It would be nice to see these hubs available in different colors, which is hopefully coming now that Extralite has begun to show different colors in some of their other parts(of course this is just speculation on my part) The price isn't the lowest nor the highest, and the hub is actually a decent value for it's performance and weight. The flange placement, bearing size and easy serviceability of the hub make this one of the lighest hubs that I think could be considered for a daily rider. Customer service from Extralite has been really great for the last several years.

Ron: No experience with the new hub... there were some minor issues with the old one. Hopefully those have been sorted out and this is a fitting mate to the SX rear.

----------------------------------------------

Ligero Road
Image

Manufacturer: Ligero
Model: Front
Notes: Radial lacing allowed.
Weight: 93gr
Available drillings: 20
Bearing material and other bearing notes: Ceramic with Phil Wood stainless option
Bearing size: 6803
Bearing static load: 276
Axle diameter: 17mm
Available colors: Black, Blue, Gold, Green, Orange, Pewter, Pink, Red, Silver
Price in USD: Apprx $200 (sold as a pair for $600)
Flange diameters: 36mm
Center to flange: 38mm
Bracing angle: 7.7

Summary: A long awaited for hub from Ligero. Unfortunately I don't have much experience with them since they are so new but I have had them for a little bit and can find some things to say. The bearings are noticeably smooth, large and have a high static load capacity. However there is no preload adjustment. The hub arrived with a slight amount of play but a quick press with the bearing press took care of that. Again I think that's related to a pre-production issue, as I did rush them to get me a set in a hurry so we would have time to play with them before writing this. There is no pre-load adjustment on the front but once the bearings were settled it's ability to resist compression from an overly tight skewer was quite good. I had to close the skewer with far more force than necessary to get only slight binding at all. Also at 93 grams the hub was quite a bit over the claimed 70gram weight, still lighter than some of the hubs in the test. I was later told that the original 70gram weight I had was not what they had settled on for final production weight. The production version is expected to weigh 85 grams, and will be slightly different than this test one. The flange placement is wide, the bearings are large as is the 17mm axle. Ideally this hub should build quite a stiff wheel. Ceramic bearings are included stock, but you have the option to swap them for Phil Wood stainless without a change in price. Also the workmanship and finish on the completely American made hub is very nice.

Ron: Another new US made hub, and like the Chris King, it comes in a wide array of colors. Interesting and pleasing shape. It should be a solid hub, but the weight is a little high.

----------------------------------------------

M5 Flanged
Image

Manufacturer:M5
Model: Flanged front
Notes: No radial lacing, 75kg weight limit.
Weight: 33gr
Available drillings:16/20/24
Bearing material and other bearing notes: Stainless
Bearing size: 688
Bearing static load: 135
Axle diameter: 8mm
Available colors: Black
Price in USD: $150
Flange diameters: 21.5mm
Center to flange: 36mm
Bracing angle: 7.2

Summary: The M5 flanged front hub is a weight weenie hub. Not only is it the lightest hub in the test, but to my knowledge is still the lightest hub on the market. This super light weight does however come at a trade-off. To get the weight down to an incredible 33grams they had to start with a very small hub shell. Which in turn means small bearings and small axle. The 72mm flange placement is middle of the road for front hub widths, so nothing is really lost there. The small bearings should have very little resistance but at the same time have the lowest static load of all the hubs. They also will have the shortest life span due to both impact failure and general wear. The hub has no preload adjustment and is very sensitive to how tight a qr is. Clamping the hub in a truing stand very tightly with a strong skewer results in a hub that is almost impossible to turn by hand, so if you have this hub, please pay attention not to tighten the skewer too much. This hub is good for a lightweight riders race wheel or for a show bike, ww bike or low mileage bike. Please not the 75kg rider weight limit. This isn't the hub to choose for your daily rider wheel set, unless you are okay with regular bearing replacement. Customer support direct from M5 has left something to be desired in the past. But if you are after the lightest wheel set this is your hub.

Ron: In my opinion you need to be pretty weight obsessed to go for this one... but plenty of people are and have been quite satisfied with it.

Soul-Kozak Classic Road
Image

Manufacturer: Soul-Kozak
Model: Classic Road
Notes:
Weight: 52gr
Available drillings:18/20/24/28/32
Bearing material and other bearing notes: Stainless
Bearing size: 689
Bearing static load: 151
Axle diameter: 9mm
Available colors: Black
Price in USD: $95
Flange diameters: 31mm
Center to flange: 38mm
Bracing angle: 7.7

Summary: Like the M5, the Soul is also a WW hub, but is reigned in a bit more to make it a little more of a real world hub. At 52 grams it features a slightly larger bearing with a bit more static load capacity, which should still roll with very little resistance but offer at least a bit more durability. The axle diameter is also increased slightly to 9mm. The hub flanges are larger in diameter but some of the thinnest of the test. The hub also tries to add wheel stiffness by pushing the flanges out quite a bit, with the exception of the Elf and the Ligero nothing in the test is wider. The hub is available only in 1 color but is a really good value. When looking at weight vs price, this made in Poland hub has to be one of the best choices. Customer Service with Soul has to date been nothing but pleasant experiences.

Ron: Looks pretty good if you're wanting a light hub, plus the price isn't bad. The tiny bearings and axle are not inspiring though. I'd have a tough time picking this over the Alchemy considering that the weight difference is only 14g.

Summary: The Mig45 is the 2nd lightest hub in the review. It's also the most expensive front hub. The Mag45 balances it's characteristics very nicely. It has fairly wide flange spacing, straight pull spokes, decently large bearings a fairly stiff carbon axle. Overall the hub builds into a lightweight, stiff, smooth rolling wheel. The straight pull spokes should be less prone to breaking than a j-bend, but at the same time can be more of a hassle to deal with if they do break. Finding the proper straight pull spoke at your LBS may not be the easiest option, so if you build a wheel with one of these, it's a good idea to pick up a few extra spokes. One drawback to this is that getting parts can be quite a slow process in the U.S. Customer service with Tune has been very good to deal with but international shipping can tend to make things slower if you're in North America. This is certainly one of the best looking hubs available with it's aluminum shell and carbon reinforced ends. There is no preload adjuster on this one but it doesn't seem to suffer much from tightening of the skewers.

Ron: I guess I'm not as thrilled with the looks as you are, but if you like the looks of the Mag150, then this is the one that goes with it. This is a good hub for a light build if money is no object. The bearings have a higher load rating than other hubs this light.

Notes:
Weight: 74gr
Available drillings: 12/16/18/20/24/28/32/36
Bearing material and other bearing notes: Stainless
Bearing size: 6802
Bearing static load: 219
Axle diameter: 12mm

Price in USD: $188
Flange diameters: 37.5mm
Center to flange: 35mm
Bracing angle: 7.1

Summary: The Mig70 is Tunes mainstay front hub. It is one of my favorite front hubs due to it's balance of characteristics. Good weight, good price, good bearing size, good bearings, good flange spacing, good drilling selection, good color choice, good axle size and a functional preload. The preload is basic but is accomplished through a threaded end cap and a drop of locktite, similar in concept to the Elf front. Self aligning flanges are a nice addition to it's already well balanced design. This is typical a bolt it and forget it kind of hub. Very rarely have there been reported problems with these hubs and when there are typically it's related to improper lacing. Radial lacing is recommended only on lower drillings. This is one of my go to recommendations for someone that wants a do it all hub.

Ron: I haven't had any issues with this hub... no drama. The bearings aren't huge for it's weight but adequate, and this hub is a good match for the Mag 180 rear.

Axle diameter: 12mm
Available colors: Black, Silver
Price in USD: $130
Flange diameters: 35mm
Center to flange: 36mm
Bracing angle: 7.2

Summary: At almost 100 grams it's almost into the realm of standard weight hub. It has a very high load capacity on it's bearings, a good axle size and a good flange spacing. It is certainly a durable hub and can handle all sorts of different lacing options including heads in radial. The price makes this an appealing durable on a budget hub. While I'm not a big fan of the set screw preload adjuster, it is functional and resists compression from the skewer in all but the most extreme cases. Drilling options are plenty, but color options are limited. The hub seems to weigh more than it needs to, but I suppose that's partly responsible for it's durability.

Ron: I like this hub. The bearings are a good size, it's pretty, and it spins very smooth. I kind of like the collar with set screw... it makes it easy to take up the clearance without the chance of preloading. They could surely drop a little weight but compared to the H3 rear it makes sense.

Bracing angle, Shimano: 7.6/4.1
Tension differential Shimano: 54%

Summary: Long overdue, but likely worth the wait. Several times delayed, with the last being because of the release of Campag 11, which the hub has now been refined for. One of the overall highest static loads of any hub in the test partly because of it's 5th bearing, which is functional in other ways as well. The bearing which is fitted over the outside of the free hub body between the splines and the pawls press fits into the hub shell and helps keep the body concentric under heavy load. The ORC also features a sleeved axle. The sleeve increases the axles diameter from 17mm to 20mm at the point where a freehub body could cantilever a little under hard acceleration. The Orc also has the widest drive side flange placements which is partially enabled in the Campag version by pushing the actual width from 130 out to 131.6mm. The hub will undoubtedly build one of the stiffest rear wheels possible, but this does come at a weight penalty. Not that 222 grams is too heavy for a rear hub, but it certainly isn't too light. This hub has been built with a large, strong rider in mind and is likely overkill for the small rider. Being a small rider I look forward to seeing what they do with a lighter version in a year or two. By adding red to the color choices for 2010 they've covered the bases with the most common color requests. Personally I'm not concerned with how loud or quiet a hub is, I almost prefer a severely loud hub. The Orc is on the quiet side as far as rear hubs go. Parts are readily available but in order to overhaul the hub correctly, special tools are needed. Alchemy will have free loaner versions ready to ship should anyone need them, but they will require a deposit. Personally I think if you're going to buy this hub you should just buy the tool kit to go with it.

Ron: This hub was in development a long time. Many people thought this was an indication that the company was flaky, but the truth is pretty much the opposite. They just wanted make sure it was thoroughly tested and as good as it could be before it was released. The goal was to make this a very stiff and smooth hub and I think they've succeeded. My impression with the ones I've seen so far... and the prototype I've been riding since last summer... is that the dimensions are very precise, ie excellent fit and alignment of the components. One if it's best features is that it squeezes out every last tenth of a mm of driveside offset in both Campy and S versions. As described earlier this allows optimization of both the lateral stiffness and tension ratio. The bearing arrangement is pretty standard except for the addition of a large diameter bearing at the hub/freehub interface. This effectively takes chain loads off the axle at this point and puts them into the hub instead. It also stiffness the whole structure. As Jason mentioned, this is not a weight weenie hub. In the early stages, a 200g weight was the target as well as the inclusion of a Ti freehub. A desire to make it conservatively robust without driving the price and weight too high has resulted in the present design. Visually it's pretty utilitarian, which will appeal to some and not others. I don't think servicing is a big concern... a lot of hubs need some special tools to completely disassemble (like Chris King, DT, Tune, etc) and tools for the Orc will be available to lend or buy. Also the bearings are shielded well by the end caps, to minimize the intrusion of water and dirt.

Flange diameters, L/R: 39/47
Center to flange, Shimano and Campag: 38/16.5
Bracing angle, 7.8/3.4
Tension differential Shimano: 44%

Summary: Like the 76/78 front hub this rear hub should be a strong consideration for anyone on a budget. Good quality Phil Wood bearings are stock, but like the front, the ceramics just feel impressive in your hands. Perhaps the best thing about this rear hub is it's interchangeable freehub body, without requiring any redishing of the wheel. This and the DT are the only hubs in this review that have that ability, and this one is even quicker/easier to swap than the DT. A body change can be done in under 1 minute and without any tools. The trade-off for this ability is a smaller bracing angle and less lateral stiffness in a Shimano version. It also means that a ds flange moved left gives a bit more spoke tension balance, at 44%(in our example case) this hub is nicely balanced. I also like that the hub shell is forged instead of machined. Radial lacing is allowed on all of the hubs except for the 32h. Color choices are limited to black and silver. So far there has been 1 report of Campag 11 compatibility problems. The freehub body is one of the quietest ones available. No special tools are required.

Ron: The guts of this hub reminds me of the last generation of the Zipp hub, right down the bearing size and the pawl design. The axle slides free but there are spacers between all of the inner races, and it all becomes a solid unit when QR pressure is applied to the end caps. Precise dimensions are necessary to avoid excessive preloading, and for this reason C-4 machines the axles and shells stateside so they have more control. The Phil Wood stainless or ceramic bearings are nice. As Jason mentioned switching between Campy and S is super easy... which is great if that is something you want to do, and less than ideal if you are just running an S drivetrain. The bearings have a small load rating which would probably make it less than ideal for heavy riders. I'm scratching my head over why a 6902 is on the outside of the S freehub while otherwise there are 6802s throughout... that is a lightly loaded area. At least it doesn't hurt anything other than add a few extra grams of weight. I would have preferred a smaller NDS offset too (~35-36mm instead of 38mm) since it gives more viable options for lacing patterns. Their offset is pretty common though and works well for lacing heads-out. Overall a good hub I think, especially for light to medium sized riders on a budget running a Campy drivetrain or wanting to swap between the two types.

Flange diameters, L/R: 51/51
Center to flange, Shimano: 34.5/19
Bracing angle, Shimano: 7.1/3.9
Tension differential Shimano: 55%

Summary: Typical Chris King quality and then some. Plenty of large bearings with more than enough load capacity. New seals have lower drag and make new hubs feel smoother in your hands. Also the needle/roller bearing that is present at the freehub body in the classic has become a cartridge in the R45. While not the lightest hub, it is definitely light for a Chris King hub. The price is really pretty impressive especially since the added ti over the classic should have increased it's production cost. It's available in 10 colors including some that are really unique such as root beer. Parts are easily available and it is user serviceable, but does require special tools. The tool kit for the classic does not work with the R45 and the new add on kit isn't yet available. This hub is significantly quieter than the classic version thanks to it's lower number of engagement points and it's titanium drive and driven rings. The reduced number of engagements means that it does have more degrees of free movement before the pedals engage compared to the almost instant engagement on the class. Not the widest range of spoke drillings, but an adequate number down to 20h. A significantly rightward placed DS flange with a good diameter, large axle and bearings should produce the ability to build a very stiff wheel laterally and one that resists windup and cantilevering of the freehub body well. At 55% tension left to right this is about as far as we'd consider adequate, but certainly not across the line of ideal. There also isn't any option for a Campagnolo version, and with it's 17mm axle from end to end, it's not even a future possibility. I love the cutout in the mid sized nds flange giving it a bit of an old school look and it's overall function, but would like to see a ti or stainless freehub body available as an option in the future.

Ron: I think this hub will be very popular. Chris King has earned a great reputation with their MTB hubs and I'm glad to see they've finally developed a set specifically for road. It should be reliable and strong, with high capacity bearings all around, and still a low weight. They addressed some of the most common complaints with the MTB design, namely initial drag and noise. I'm not in love with the high NDS flange... I would have preferred a small flange and a few grams of weight loss. The flange spacings seem ok to me. At least they've moved the DS flange over as much as possible, and as long as radial heads-in is allowed on the NDS, you can still build a stiff wheel.

Price in USD: $395
Flange diameters, L/R: 45/45
Center to flange, Shimano: 32.5/16
Bracing angle, Shimano: 6.7/3.3
Tension differential Shimano: 49%

Summary: The 240 hub was included in this review because it is such a dominant force in the wheel industry. So many companies use it as their hub that it has become a sort of "standard" so I thought it would be nice to see how it actually compares to the other boutique stuff. It's not the heaviest, there are 3 others that are heavier, but all of them have much higher static loads, and all of them have much larger bracing angles resulting in a much stiffer/stronger wheel. The DT is competitively priced falling right in the middle and has a very middle of the road static load capacity. It has the smallest DS bracing angle of all the hubs tested, including other interchangeable bodied hubs but at least this provides a decent tension difference of 49%. The DT uses a ratchet drive instead of a standard pawl system, and the ratchet systems seems to have a very good track record for reliability. The hub is easy to overhaul and needs special tools only to remove the splined half of the ratchet system in the body. There are two things about this hub that are very appealing to me. I like that you can easily change from Shimano to Campag and back again in only a couple of moments, of course this comes at the noted reduction in flange spacing. My biggest draw to this hub is the way it's become completely widespread in the industry. This is good for anyone who needs service or parts. You can walk into your local shop and there's a good chance they'll have whatever parts and knowledge are needed to maintain it. Customer service with DT isn't the greatest or the quickest, but luckily as a consumer there won't be many opportunities for you to have to deal with them. The noise in this hub is a bit on the loud side, but not overly so and can be quieted with some lube. On a 1-10 scale for noise with 1 being a silent clutch and 10 being a Tune Mag90, I'd say the DT is a 7 in noise level.

Ron: Definitely a decent reliable hub and at a good weight as well. The bearings are large enough and they rarely need overhauling. Lubing the freehub mechanism is a very easy job. The biggest negative is the less than optimum flange offset on both sides. Plus the price has been creeping up. I've used a lot of these in the past, but doubt I will very often in the future now that the Alchemy, C-4, and Chris King hubs are available. DT sells these pretty cheap for OEM applications, which reduces their value for customs in my opinion.

Summary: The SX is the definitive weight weenie rear hub. If you are after lightweight, there is currently no other choice. Amazingly the SX manages to combine super lighter weight with some decent specs. One would expect the lightest hub in the test to also have the lowest static capacity on the bearings. The straight pull DS spokes add some reliability to the wheel as well as a decent DS flange spacing. The 17mm axle provides decent rigidity as well. The hub is one of the more expensive in the review, but not the most expensive, and cheaper than a couple that weigh more. A pretty ideal hub for a race day or climbing wheel. Probably not the best choice for a daily rider except for light, gentle or low mileage users. Getting replacement parts is quite easy with Extralite as the customer service is quite responsive. International shipping can cause delays though. The hub has a nice and easy to use externally threaded pre-load adjuster that resists compression well. Like the front, I'd love to see this hub available in a range of colors, and hope that it is in the plan. The hub runs generally quiet, quieter than most. When this hub and it's weight were announced, I expected that it would be a troublesome hub with lots of problems. So far over the last year it has turned out to be quite a nice hub and has been really quite trouble free. It does require a little maintenance, but no special tools are needed.

Ron: I was initially skeptical of the SX, but it has exceeded my expectations... which at this weight means that it is reasonably durable. Using plastic bushings for the left side freehub bearing seemed a likely problem area but I've not heard any complaints yet. Also, there are only two pawls and they seem rather wimpy, but there haven't been any issues there either. The bearing sizes are even sensible. The flange offsets are less than ideal, but it's normal when you have straight pull spokes on the DS. Considering it's competition in this weight class it is a pretty good value at $540. It should definitely be on your list if you are putting together a very light bike.

Price in USD: $495
Flange diameters, L/R: 34/50
Center to flange, Shimano: 43/17
Bracing angle, Shimano: 10/4.3
Tension differential Shimano: 43%

Summary: The predecessor to the SX the SR isn't all that different. J bend DS spokes as opposed to the SP. A smaller right shell bearing means a slightly lower total static capacity. The axle in the SR is a stepped 20mm/17mm and the flange placement is on the wide side. It's less expensive than the SX as well. Same pre-load adjuster. Unlike the SX It does however lack the ability for a freehub body to be changed from Campag to Shimano and back as it requires some micro shims and is ideally done at the factory. Of the very few hubs in the 150gram weight range this is certainly the best value. Again a good race hub or special event hub, however, I do use one of these on a daily rider set of my wheels that get lent out regularly. They've seen tons of miles and have remained trouble free. They also have a good tension difference ratio, and allow radial lacing as long as it's heads out.

Ron: Not much to say on this one. People who are weight conscious enough to go this light might as well go for the SX and drop another 23g.

Flange diameters, L/R: 41/60
Center to flange, Shimano: 49/18.5
Bracing angle, Shimano: 10/3.9
Tension differential Shimano: 72%

Summary: The U.S. made Ligero, is the only Triplet hub in the test and has some different aspects to consider than the others. First the common traits: The bearings are ceramic stock, and spin very smooth. This hub also has the highest static capacity, topping the Orc and H3. Weight is on the heavy side, in fact only the H3 is heavier, but I'm told the production version should be 9 grams lighter than this one. Price is average, though it is only sold as a set. Customer service has been really good so far. Available in a ton of colors, though I should note this is not a final production hub, at the very least it's lacking the laser etching that will be present on them. The noise of the freehub body can be considered to be fairly quiet. Now for the triplet stuff. The idea is that normally by halving the number of nds spokes you increase their tension required to pull a wheel into dish and the result is a rear wheel that has fairly even ds and nds tensions. In this case they decided to reintroduce some of the tension difference and push the left flange out even further to gain back most if not all of the lateral stiffness lost when going to triplet. The result is flanges with the widest spacing and still good tension difference. This does limit rim choice as a rim needs to be fairly stout and center drilled to work ideally with triplet. The flange size combined with the triplet pattern laced in the recommended 1x/3x should resist windup quite well. One interesting thing about the hub is the nds flange is 4mm thick. This means it's optimized for Sapim spokes and while not impossible to use DT spokes, it certainly takes a lot of work to get the shorter elbow to feed and sit properly. The other thing I liked about this is that the tools are incorporated into the design. Pull the axle, remove a piece, turn it around, insert it again and it will push out a bearing. Pretty clever.

Ron: Triplet is one of the few "unconventional" lacing configurations that actually makes sense. By making the NDS offset very large they can achieve good lateral stiffness while still having a high tension ratio compared to conventional hubs. I think Ligero is using about the optimum flange offsets for this design. As Jason mentioned the torque transfer is quite good as well. The only downsides of triplet that I know of are that a fairly stiff and center-drilled rim must be used, and if an NDS spoke happens to break, then the wheel will warp more than a conventional build would. This hub has an unusual bearing arrangement... essentially the same as the Alchemy, with a large diameter bearing at the freehub/hub interface, only with the right side hub bearing missing. At first I thought this was a bad idea since it requires that hub shell-axle loads be carried by the freehub bearing, but since the freehub bearings each have a 390kg capacity, they should be up to the task. The massive bearing on the outside of the freehub should be more than enough to take chain tension loads. Overall a very solid hub... but heavy.

Flange diameters, L/R: 32/54
Center to flange: 35.5/18.5
Bracing angle: 7.2/3.9
Tension differential Shimano: 54%

Summary: Made in the Netherlands the M5 hub comes in at a pretty light weight of 185 grams. However unlike some of the others it gets down to that weight through a reduction in bearing sizes making this the rear hub with the lowest static capacity. The small bearings do indeed spin nice and smooth and with little resistance. The M5 does have a nice right flange placement being equal to a Shimano version of the Ligero and 2nd only to the Orc. Large DS flange should also work well to resist windup. This hub seems to fall into an odd spot in the lightweight range. It's mid 180grams which is a very respectable place to be in weight. In this weight class the main reason I would recommend this over the Tune Mag180 would be price. However if one wanted to be in this weight class and was concerned about price, the less expensive and 15 gram lighter Soul-Kozak would be my recommendation. I like the look of the hub but just think it seems to fall into an awkward place of weight/price.

Sorry I don't have a picture of the inside of the M5 hub. I have a set of Edge wheels built onto M5 flanged hubs but for some reason have been unable to find them lately. I'm not sure where they are, but it's likely that someone borrowed them and I just forgot who. I'll add in a picture if/when my set returns.

Ron: I haven't felt compelled to use this hub at all since the weight and price were about the same as the Tune Mag180 which had a better following and reputation. The bearings are on the small side.

Summary: The Polish made Classic road hub is really ideal for a weight weenie on a budget. At 168grams, only a couple hubs in this test were lighter, and all were far more expensive. What I like about this hub is that you get a well functioning hub that is light and priced really well. While the static capacity is the 2nd lowest of the test it isn't far off some of it's competitors. The bearings spin smooth but with some noticeable seal drag. Like the King classic hub the seal drag does go away with a couple hundred miles as it wears in and should contribute to keeping the bearings free of contamination. The left bearing is one of the furthest outside bearings in the review. Dis-assembly and reassembly is easy and quick. Overall a very nice balanced weight weenie hub. The hub would be consider a bit on the loud side.

Ron: I like this one better than the M5 as well. At least the right hub bearing is a little larger, and it comes in at an attractive weight and decent price. The flange offsets make heads-out radial the best choice on the NDS. The older models did not earn high marks for durability, and hopefully they are better now.

Summary: Being that this hub is not yet available I probably shouldn't have included it in the review, but since I do have one, I figured why not at least give some more info on it. What I like most about this hub is what everyone probably likes, the weight. 99grams for a rear hub is incredible. I also really like that they departed from their designs of the past and tried something new with this one. A ratchet system similar to DT's but made of aluminum instead of steel. One side of the ratchet is simply machined into the freehub body and the other is a replaceable piece that just rests inside the hub shell. In place of the springs they use 3 pairs of magnets with like polarity that repel each other. Tune is not the first one to use magnets in a ratchet system, Soul Kozak has been doing it in their mtb hubs for quite a while, but Tune has really managed to take this down to an absolute minimum weight. Tune also removed the XoT bearing and went to 4 equal sized full ceramic bearings for further weight savings. They managed to drop weight enough from the drive components that they were able to put an aluminum axle back in replacing the carbon one from the 150/160 and still stay under 100grams. By going to an alloy axle they changed the way in which the hub can be serviced and made it much more user friendly. What I don't like about this hub is that it isn't available and won't be for a little while still. Even when it does get released it will be sold only in complete wheel sets and not as a hub. I also have to wonder about the long term durability of the aluminum teeth. My understanding is that there is a treatment on the aluminum that makes it quite a bit stronger than standard. I also don't like what I think the price has to be. There has been no official word from Tune on the price, but just by having 4 full ceramic bearings they will have to put a hefty price tag on the hub/wheel. What I am excited about is to see how this works out and what can happen if they trickle it down into the 180 range. For those of you bothered by loud freehub bodies, this may not be an option as it is easily the loudest freehub body I've ever heard.

Ron: An interesting exercise in weightlessness. The bearings are even a decent size, but since they are full ceramics they are quite light. With a matching 30g front hub, they'd certainly have a winner... at any reasonable price... if they can hold up to modest use.

Tune Mag150

Manufacturer: Tune
Model: Mag150
Weight, Shimano: 155gr
Available drillings: 16/20/24/28/32
Bearing material and other bearing notes: Stainless
Bearing size, hub shell left: 6902
Static load: 434
Bearing size, hub shell right: XoT (6902 half)
Static load: 434
Bearing size, freehub body: XoT(6802 half) and 6802

Price in USD: $815
Flange diameters, L/R: 28/54.5
Center to flange: 35/17
Bracing angle: 7.2/3.5
Tension differential Shimano: 49%

Summary: Tunes current flagship hub, 155grams makes it lighter than everything except the SX. For a hub at this weight it has plenty of large bearings and a high static capacity. The bearings spin buttery smooth but with a slight amount of seal drag. Straight pull nds spokes, carbon axle, carbon reinforced ds flange, and decent flange placement. Really this has everything a weight weenie would need in a rear hub. The drawback is the price. Short of the Mag90 this is by far the most expensive hub in the review. So while it has a lot of good qualities, it is probably not something I'm going to recommend over the Extralite, except for maybe a larger rider or someone who wants a really light daily rider, or has absolutely no concern about budget. This hub requires a pretty vast collection of special tools to maintain and overhaul it properly. This is where I have to give an special, super thank you to Jeremy from Alchemy for making us the custom tools required by some of the Tune stuff. Pictured is my kit of Tune tools, part are stock tools from Tune but the other half all were custom made by Jeremy and are designed to be used in conjunction with his wizard press. The XoT bearing in the hub is a unique bearing that combines a 6802 and 6902 bearing into one single bearing. Basically both bearings share the same inner race. One half of the bearing is pressed into the hub shell the other into the freehub body. This helps to prevent cantilevering of the body and helps to keep it concentric. This also means that finding an original replacement may not be the easiest thing as it is a Tune specific bearing. It is possible to replace the xot with a 6802 and 6902 bearing if necessary.

Ron: An exotic light hub with good sized bearings, a carbon axle and shell reinforcements, and a Ti drive ring. If the 911 GT3 RS is your car, then this is your hub... paired with the Mig45 front of course.

Tune Mag160

Bearing size, hub shell left: 6902
Static load: 434
Bearing size, hub shell right: XoT (6902 half)
Static load: 434
Bearing size, freehub body: XoT(6802 half) and 6802

Price in USD: $635
Flange diameters, L/R: 41/54
Center to flange: 39/18
Bracing angle: 7.3/3.1
Tension differential Shimano: 46%

Summary: Tune's 160 is approaching a hub that is more suited for most riders. This hub is simply a combination of two others. Take the flanged hub shell from the 180 and use the internals from the 150 and what you get is a 160. So while it lacks the lighter shell of the 150 it also lacks the time involved in building the carbon reinforced shell. This helps to drop the price by almost $200, making it a bit more real world price and only 13 grams heavier. At 168 grams it's still plenty light. It does still require most of the special tools that the 150 does. So you get the advantages and disadvantages of the XoT bearing, carbon axle, titanium drive ring and with the more user friendly shell. I had an older version of the 160. For 5 or 6 years it was used by different riders almost daily, and built into a ton of different wheel sets. I never expected it to have the lifespan that it did, but it finally died about a year ago when the carbon axle cracked. I sent it to pk0r (Nils) and he put a new carbon axle in it and returned it to use. He will put a ton of additional miles on it. It's long term durability has been quite impressive to me.

I did not include an internal picture of this as the inside of the shell looks exactly like the inside of the 180. All other parts are that from the 150.

Ron: Not on my recommended list. Yes, it's $200 less than the Mag 150 and it's only 13g heavier... but it's also over $200 more expensive than the Mag 180 only only 14g lighter. It also looks just like the Mag 180... and when you are in this price range style matters. Having the looks of the Mag 180 and the finicky guts of the Mag 150 just doesn't work for me. If they'd done it the other way it would have been better.

Bracing angle campag: 8/3.3
Tension differential Shimano: 46%
Tension differential Campag: 41%

Summary: The Mag180 is certainly Tunes most popular hub, and by far one of our most used/recommended hubs. The reason for that is simple. It has a great balance of characteristics. Good flange placement, plenty of bearing load capacity, smooth rolling bearings, the XoT's reinforcing inner race, simple preload adjustment, light weight, decent price, a wide range of colors, a large number of drilling options and just good overall performance for riders of all sizes. So while this is a very nice balanced hub, like all others it has it's drawbacks. First is that last year they developed a problem of creaking noises. Thankfully this has been resolved with a change in spec on the titanium drive ring. There is also the availability of the XoT bearing, but again it's possible to replace this with individual bearings if needed. Thanks to the alloy axle in place of the carbon one it is possible to overhaul the hub without special tools, though having the tools makes it quicker and smoother to do. The hub would be considered to be on the loud side. Also this is one of very few hubs that is available is the always striking white color.

Ron: This hub has garnered a substantial following in the "light but not crazy light" category. It lost some luster for me when the creaking issues showed up and Tune was very slow to respond. If that has now been fixed, then they've returned to viability. All the pluses that Jason mentioned are valid, but in my experience service from Tune tends to be slow and inconsistent. They offer a lot of color options, but if you want something special, then expect a long wait... and if there is a problem or a part is needed the wait can be very long, too. I guess I've been getting spoiled by the great service from US based companies. Sounds like I'm pretty down on this one... but that isn't really true. It's more like I'm jaded, but could be brought back around.

White Industries H3

Manufacturer: White Industries
Model: H3
Weight, Shimano: 248gr
Weight, Campag: 265gr

Bearing material and other bearing notes: Stainless
Bearing size, hub shell left: 6902
Static load: 434
Bearing size, hub shell right: 6902
Static load: 434
Bearing size, freehub body: Campag 6802 x4
Bearing size, freehub body: Shimano 6802 (pair) 6902 (single)
Static load campag 6802: 219
Static load shimano: 6802: 219, 6902: 434
Axle diameter: 15mm
Freehub body material: Ti
Available colors: Black, silver.
Price in USD: $265
Flange diameters, L/R: 40.5/55
Center to flange Shimano: 36/18
Center to flange Campag: 38/16
Bracing angle shimano: 7.4/3.8
Bracing angle campag: 7.8/3.3
Tension differential Shimano: 50%
Tension differential Campag: 42%

Summary: Made in the U.S. the H3 has one of the highest static capacities of the test, but should be expected from a hub in this weight class. At 264grams for the Campag version it's the heaviest hub we reviewed. It has large bearings that spin smoothly, and an easy to use preload adjustment, though not my favorite design. It also has a nice outward position of the left bearing. At $265 it is a very reasonably priced rear hub. In some cases it seems almost over built, such as having 3 or 4 bearings in the freehub body. One thing that makes it heavier is also the thing I like most about it, that is that it is the only rear hub in the review to have a ti freehub body. This is great for riders running Shimano who are tired of the alloy bodies being grooved by cogs. I also love the look of this hub in silver, this is one of the best looking silver hubs I've ever seen, yet at the same time, the black version just doesn't look as good to me. White industries is easy to get a hold of and customer service from them has been good.

Ron: This has been the most popular hub I use. It's strong, has a large bearing capacity, it looks nice, has a Ti freehub, and the price is good. I think it's the only hub in this review that has a steel axle. The weight is also higher than others in this review, but it is still not bad. It's easy to build solid wheelsets with the H3 that are in the 1360-1500g range, which makes them lighter than comparable factory wheels that are much more expensive.

This is probably a good place to mention something about shell materials. White Industries is one of the few that uses the common and boring 6061 aluminum alloy for their shells (Alchemy is another). Most manufacturers use a very high strength alloy, and at first glance this seems like a good idea. Stronger is better, right? In this application though, I think that 6061 is better choice. The reason is that 6061 has higher corrosion resistance, and more importantly resistance to something called "stress corrosion cracking". The spokes exert concentrated and variable forces at the holes in the hub flanges, and high strength is a less important factor than ductility and corrosion resistance. Hubshells normally fail when cracks develop and grow at the spoke holes, and the flange eventually pulls away. Unlike many manufacturers White Industries hubs have no restrictions on lacing and spoke tension, yet I've not heard of a single one suffering a flange failure. Another advantage is that the softer alloy will deform more readily providing better support for the spoke in the flange. It is also one of the reasons why the silver hub looks so pretty... it is polished bare metal with no anodizing... yet is still corrosion resistant enough to stay shiny in most environments.

Awesome review really liked the fact that you've managed to sneak in something that's not on the market one of the many reasons that make this forum invaluable. I maybe answering this myself but is the DT swiss 190 not included because it is essentially the same hub but with ceramic bearings?

This is really fantastic! Thanks to you both for compiling this. It's like the crank database. Very valuable to weight weenies around the world!
Jason showed me that 99g Tune hub last year and thankfully it's not available...coz currently I'm running the lightest combination in the database that you can actually buy and get Jason to build up!
...and I understand there's compromises to be dealt with. But I ride my 780g wheels 4 times a week, with no real problems. But I'm not racing death-crits either.

Again, thanks so much for this! It makes for great reading.

Good info. Nice spread of hubs. Really don't care much about the weight comments, as the numbers pretty much say it all. It's really nice to see some hubs that aren't built with the weight weenie ethic.

Can you provide more information on applying the bearing static load number to actual wheel builds. Besides higher is better, what does it practically mean.

ie. What is a minimum threshold in your opinion for a 150lbs racer?
