Origin-8 brand stems fit into French steerers.
 
I just received several stems and measured their quill diameters. The three ORIGIN-8 stems measure no greater than 22.0mm, slightly less in places, so are sure to be a real time-saver versus filing down stems as I have often resorted.
EDIT; I test-fitted one into both a PX10 and a Urago, both are from the 1960's and so definitely both 22.0mm spec.

Though rather heavy, these very inexpensive stems are sleek and beefy, with notable extra material surrounding the tapped hole that runs up into the bottom of the extension, just behind the clamp. They are otherwise much like a copy of the ubiquitous "SR Custom" stem iir, which was possibly the most mass-produced stem ever.

I found that the logo was very easily removed with wetted, medium steel wool, leaving no blemish to the original, smooth finish.

Also, that the clamp diameter, at my measured 25.56mm, will likely work either with 25.4mm (as intended) or 25.8mm handlebars.
EDIT; I did test-install a pair of TTT bars, but it took much spreading force from an Allen key being wedged in and rotated 30 degrees. So I'm uncomfortable recommending this stem being used with bars larger than 25.4mm.

I am quite pleased with this find. A shiny, sturdy 10cm stem for an old French bike is an oft-needed part(!).
Just don't use it with a 25.0mm French handlebar(!), which are almost always too narrow anyway.

Note that most true 22.0 French stem quills measure at least a tenth of a millimeter smaller than 22.0mm, with many even measuring well under that, so I don't consider these stems at all unsafe to use in the intended 22.2mm ID steer tubes, especially as the slant/wedge design isn't vulnerable to cracks developing from any over-expansion of the quill by a cone-type of wedge.

Hmmmm.....I did not know that they included Russian made, heavy gauge, reusable condoms with VO stems these days....
What will they think of next??:rolleyes:

Apparently there is a long-standing tradition of such. Yes, quite re-usable, contains the grease well enough even on pull-outs.

Ignoring the subsequent details, I do want to thank you for this. Especially on the test to remove that hideous logo. I have two French bikes and could use inconspicuous stem options.

Thanks.

If you care about such things, they're too modern looking for any bike that would require a 22 mm stem.

Thanks for the info. I like it - nice smooth finish. Definitely like the look of this stem vs. the 70's Pivo, etc.

I've just finished installing one of the Origin-8 stems that I also modified to properly fit and grip a 26.0 handlebar.

I had to fashion a sort of reamer to apply the necessarily forceful sanding action that would maintain the straight bore centerline with even stock removal. It worked out great, and I'm just now about to finish wrapping my new, wider, Trek-sourced handlebars with a bit shallower ramp angle than the original, narrow, 25.0mm AVA handlebars.
True, that the original look has not been preserved, but I at least got the clamp and rider-fit dimensions worked out to perfection using an older bar with plain, silver center and with traditional round curves instead of some Ergo-Anatomic style. I did what I could with the parts I had, and now will be riding with a non-death stem and padded tape. I'll post a before and after of the bike in a little while.

Ok, it all done and ready for a ride. It sure will be nice to really climb the very steep ones without my knees hitting the upper level of the handlebar, even though I don't think I was able to raise the bars higher than before at all before reaching the stem's limit line. The "ramp angle" of these (Trek) "System III" 26mmX42cm bars does seem taller at the levers as shown.

This was the third frame with a 22mm steerer ID that one of these new stems went into without effort, and those plastic caps kept grease off of things while I did the many test-fitting routines in getting this stem on board. I'm sure that I will notice the stiffer handlebar mounting versus the hollow, skinny death stem.

Noting that I did have to very slightly relieve the headset locknut ID, using a Dremel, so there was an easy sliding fit.
I used the CycloLinea padded tape from Nashbar, and this tape comes up short unless you keep overlap to about 1/4" in most places. I literally trimmed zero from the ends, except for the angle cut, and that on the first try! Not bad for $5 though.

Also the generous cable lengths now border on too short, but the pro riders used to set them up that way in many cases, probably to save weight and aero drag! I can turn the bars fully with no problem, and the brakes are working great with Jagwire's cheaper pads in back to quiet a buzzy squeal against the serrated rim sidewalls.

As always, the Cane Creek hoods save the day, enabling a good build on a tight budget, while keeping the original levers (these older ones with the much-gentler curve downward, thus a little more reach).

I can also attest to the Origin8 stem purchased last week working with the French steerer of my PX-10.

Great call on the Origin 8 stems. I had been looking for a new, shorter-reach stem for my Grand Jubile, and the Origin 8 fit perfectly; a little steel wool and the hideous logo is a thing of the past. Thanks!

This is great info and very useful info on Russian personal safety products as well, :thumb:

I spent many a day humming and hawing over French eBay stems. They were either not the right size, too expensive or not to my aesthetic liking. These are pretty generic looking stems which is just fine by me and they are replacing some very nice and light but flexy for my size Ava stem and bars.
