Any French Stems That Take 26.0 Bars?

I'm considering getting a new stem for my Peugeot Competition. The stem that came with it was an Atax stem which i lost the clamp bolt for but i swapped it with an SR 22.0 stem. I'm still running the original Atax Franco Italia bars but i want to upgrade to Nitto Noodle bars, Cinelli, or 3TTT Mod. Grand Prix T.D.F

I can't find a stem in 22.0 x 26.0 for around 50 dollars so i might just keep it how it is now unless i can find it. I get lucky in ISO/Trade sometimes but i don't have much to offer right now. If anyone knows where i can find one or what to search for please let me know.

Thanks!

-Harry

sheldon says you can easily shave 0.2mm off the diameter of a 22.2mm stem using sandpaper. he actually writes that only 0.1mm is all that is needed to shave (though i'm not sure the reason it's not 0.2mm). you may need to shave the inside diameter of the headset lock nut as well. so, there's that...

I just hogged out a French stem's clamp to accept a standard handlebar. There is a thread about it over in Mechanics. Took about an hour. Used a drill press, a Dremel, and sandpaper. In retrospect, it could be done with just a Dremel and sandpaper. Works fine.

Sanding down a standard stem to 22 mm would have been easier, but the wedge is usually steel and that might be a bother to reduce by 0.1 mm radius.

Yes there are French stems for 26.0 bars. 26.0x22.2 I have one by Mavic on my Rivendell which has a Mavic Comte de Coucy handlebar, 43 cm side by 26.0 clamp size.

These are hard to find and expensive.

I think the OP was looking for a 22.0 X 26.0 diameter stem, which were never made.

Cinelli did produce 22.0 diameter stems for their 26.4mm bars.

"Sanding down" an aluminum quill is an understatement. The job can be lengthy even with a file, but hand-sanding might take hours. The thickness of metal removed from the surface is less than 0.1mm, since the quill is typically a good bit undersized and the steerer i.d. slightly over.

I always use a file and sandpaper, doing many test-fits during the process to identify the high spots or points of interference. It is a lengthy process, even though, as Sheldon mentioned, you only have to remove .1mm from the stem quill surface to reduce the diameter by .2mm.

oh, i get it now -- 0.1mm shaved off both sides of a straight (diameter) line results in a difference of 0.2mm. i made a 'd' in geometry in the 9th grade too. since, my actions often define the term 'obtuse.'

Yeah well you guys know what i mean.

I have done the sanding trick a few times but once i gave a cinelli stem to my dad and he took it down on a lathe but it was just a little bit too small which resulted in some really irritating creaking coming from the headset area on my Austro-Daimler bike.

Maybe i'll just leave it how it is now. but i'd really like to have some of those bars suggested on my peugeot.

I've bought Cinelli stems off ebay where the seller didn't realize they were French 22.0mm. Look for a countersink drilled just above the slot on the quill. That's Cinelli's French marking. I think the last one I bought was about $20 that way.
