Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

yeah if they are 25.4mm and you are trying to fit it into a 26.0mm stem just order the appropriate shim or go to your lbs and see if they have the shim you need

I have used a 25.4mm to 31.8mm shim for the last 5 years on my track racing bike w/o any problems. Functionally they work fine, but aesthetically they don't. So, it's just a matter of what's important to you.

I used my stainless RB21s (26.0) with a 31.8 Thomson stem for my aerobars using a shim. I used them in 500M and Kilo events pulling on the bars as hard as I possibly could and they didn't budge.

But, if you can find the right stem it will look cleaner.

Yeah. Aerobars are used on the track, too.

Actually, it's illegal to use brakes on any track.

This is a "kilo" (1 kilometer time trial. One of the most physically demanding events in track cycling) done by one of the best ever. I am not nearly this fast. But, this gives you an idea of the forces involved.


Tejano does some events using aerobars, too.
