Did you make the stem and bars or is this a brand I haven't heard of?

It's a neat bike, I can tell you've put a lot of time and effort into it. Welcome to the forum!

hello and welcome! nice bike and great with your homemade parts. especially the handlebar is odd. why do you use this angle for the stem? you could have one with just -5 degres and don´t have to make it this big in the "spacerway" schould be much more stiffer, lighter and easyer to make

"This brand", what I put on the stem, and bar is my strange surname, because I made it self :wink:

1. I preffer horizontal stem aesthetic.
2. It's still stiffer, than previous, normal ITM "The Stem"/spacers combination, because 1 part sleeve.
3. It gives me chance to keep longer steerer tube in case I'd like to use other stem/position.
4. Decreases torque needed to securely combine it with carbon fork, and is less stressful for steerer tube.
5. Doing it your way, I could save up to 5-6g only, considering both - stem & fork. Could be worthy, aiming around 4 kilos bike :?: :roll:

Hi K

Cool stuff you are doing! :thumbUp:

I agree with the thinking that your design offers a more gentle pressure on the fork steerer, and the idea that no spacers are needed is cool. But personally I think a horizontal stem looks a bit strange on a bike with sloping top tube. In my mind it's only allowable on a traditonal designed frame. A stem with the same rise as the top tube would be ideal, aesthetically. (And you would save a few grams + the whole assembly would be a bit stiffer)

It sounds reasonable.

This year changes to my Scott:
1. Casette from KCNC for Recon.
KCNC Ti/Alu 7075/Scandium was very tight for chain. Recon gives much more play with it's thiner cogs. It has also different ramps.
Altogether is more similar to original Campy casette, and it works similarly as well.
KCNC lasted 5040km under not very strong rider. Most of it done in the mountains. I'm doing 7km climb with 400m denivelation in around 30min.
Casette was still not skipping, even on the long, around 13% steep sections, but already lost it's anodising.
After almost 4000km Recon has bit crumpled teeth, but still working well. It's ceramic coating seems indeed to be much better, than hard anodising,
as still looks like it was new - mirror surface.
Declared Recon's ( for Campy 11-23 ) weight is 112g. Real weight is 96g!!! After shaving not working 4 notches - 93g.
2. Nokon cables changed for Alligator/Alligator mini + Power Cordz.
PC 1.2mm are barely OK to go into Mini Links, so I blamed them first for problems with adjusting rear der. But finally I've found, no matter if
you use them, or original 1.1mm Alligators. Mini Links are caused by constant compression, and rear der. needs frequent adjustment. Especially
with my style of riding. I always try to save my energy, as I'm riding long distances, what results in frequent changing gears.
3. SLR saddle changed for my 75gram padded one. I expected, it will be barely acceptable to ride long routes, but I hoped Assos will do good work.
Surprisingly this saddle is much more comfy than SLR, and even Ferrari Novus for me.
4. Mavic Ksyrium SSC SL 2005 further tuned ( after hybrid cearmic bearings, and titanium axle ending ).
Except weight loss, wheels are stiffer, thanks for CF is no stretchable material, like original aluminium. In two weeks I've beat 3 times my uphill TT
time, although I'm 50 years old, and since several years I was able to do barely good results, comparing to my previous times.
I also milled sides of the front whell, as 2005 Ksyriums are both 430 grams 25mm rims. Eventually rear wheel is 780g, front is 616g.
5. I've also found my favourites Continental 20-622 GP 4000 tires. They are 5 grams lighter, than previous ones of the same model I've had.
