Enve SES 4.5 Tune Mig / Mag Wheelset

Is This it? #01
In Stock Reminder

Product Description

ENVE 4.5 Rim

The SMART 4.5 rim from ENVE is one of the new rims, launched in 2016, that is pushing the aerodynamics of shallower rims.  In fact the 4.5 is replacing the SES 6.7 because, with the recommended 25mm tire, the 4.5 is testing just as fast. This makes sense, because in designing the 4.5 ENVE was able to take advantage of years of learning and testing since the release of their 6.7 rims in 2012. The profile changes are small but meaningful, giving you the handling and weight benefits of a shallower rim, while maintaining the advantages of a deeper rim during descents and flat terrain.

New Braking Surface and Tubeless Compatibility

The new 4.5 rim is both tubeless compatible and features the new textured braking surface featured on all rim brake ENVE rims moving forward. The textured surface is designed to reduce braking heat, a problem particularly important to address with clinchers, and to improve wet weather performance. With the textured surface it’s important to note that there’s a new black brake pad, which will be a problem if used on the old rims. In fact using the old rims with the new pad will void your warranty just as using an off brand pad will. Conversely, using the older grey ENVE pads on your new rims will not void the warranty but is not recommended as the performance benefits of the molded braking surface will be negated. For the smoother brake track the grey brake pad is still what you should be using.

Tune Mig 70 / Mag 170 Hubset

We've been selling, building, and servicing Tune hubs longer than any other company we've worked with. What started as a boutique addition to our internet shop has slowly become our go to lightweight hub for a variety of wheel builds. The very serviceable Mag 170 rear hub features a simplistic three pawl ratchet system combined with an alloy 17mm axle for a total weight of 170g, as the name implies. The Mig 70 shares the same 17mm axle and 6803 bearings as the Mag 170 with a weight of 75g for a total hubset weight of 245g. This makes the Tune Mig / Mag hubset an affordable, reclaimable, serviceable, light weight pairing to the 7.8 rims. The ENVE 7.8 Tune Mig / Mag wheelset is a supremely aerodynamic option for all riders, capable of traversing hilly race courses and all day training rides, while ditching superfluous weight and complexity.

Ceramic Bearing Upgrades for Your Wheelset

If you're looking for every bit of performance from your wheelset ceramic bearings are a detail that should not be overlooked. All Ceramic Bearing upgrades are performed here at Fairwheel Bikes using the highest quality HSC ceramic bearings. A full set of ceramic bearings will save you around 10 grams, but the true performance gains come from the precious watts that are saved over a standard steel bearing.

Sapim CX-Ray Spokes

Last, but not least, Sapim CX-Ray spokes are the go-to spoke for many of the world’s elite wheel manufacturers like Zipp, ENVE, and Reynolds. Due to Sapim’s proprietary forging process, the CX-Ray possesses the benefits of high rigidity and an aerodynamic profile with none of the performance penalties associated with lightweight spokes. In fact, each Sapim CX-Ray spoke has a tensile strength of up to 50% more than a straight gauge spoke and a fatigue life of nearly 3 times as long. That means a more durable wheel that will see you over the mountains and through tough sprints for longer than any other wheel in its class.

Sapim Drive Side CX-Sprint Spoke Option

For our stronger, more powerful riders we oftentimes will lace our rear wheels with CX-Sprint spokes on the drive side. Putting a slightly heavier and stronger spoke on the higher tension drive side better counteracts the increased stresses drive side spokes encounter, creating an overall stiffer and more durable wheel. The CX-Sprint spoke is the "bladed" version of the Sapim Race spoke (1.8mm), while the CX-Ray is a modified Laser spoke (1.5mm). The 20% extra material at the spokes thinnest part is something that lighter riders will not notice but will create a stiffer wheel for those who need it. For the Sapim CX-Sprint upgrade simply contact one of our wheel builders (information below) or add a note into your order with your wheelset.
