French dilemma

I'm just finishing up a build on my Peugeot Super Competition and decided to ditch the drop bars and go with some kind of upright bar. Well easier said than done I'm finding out since it's impossible to find an upright bar that fits the French stem clamp dimensions which is 25mm. Everything nowadays is 25.4mm I'm finding out. Don't really want to try and shave off .4mm from the bar or stem clamp the idea kind of scares me even though the bike is just an around town single speed. I'm kind of an old guy with some back issues and really don't want to put back those drop bars. Any suggestions out there? Thanks for any input.

I have seen some French stems (22.0 quill) with 25.4 clamp size. That would be your best option. You can also sand down a 22.2 quill stem to fit in the steerer.

Sanding down a 22.2mm stem quill to fit a French 22.0 steerer is no big deal. I would do that with a stem that has the clamp size to fit your bars of choice.

I have confirmed that these Origin 8 stems do fit in French headsets and have a 25.4 clamp size. I used on a build for a friend a while back.

This is another option if you wish to use a threadless stem. I picked one up a while back but haven't used it yet. It does fit though!

+3 on sanding down a 22.2 stem to fit done it a few times no big deal then you have many bar options -Velo Orange has some very nice city bars and brake levers and thumbie shifter mounts if you want to go whole hog

I can second this — I have two bikes with French-size steerers on which these stems work. I think this stem is also available with a 26.0 clamp, which widens options.

Nitto Technomic stems are often actually 21.9 mm and will fit French steerers without sanding. You may have to open up the headset locknut on some headsets. They come with 24.4 and 26 mm bar clamps.

Philippe and Milremo stems @25.4. I have reamed a Pivo (which had lots of metal) to 25.4.

Actually no, they are marked 22.2mm but measure 22.1mm. Reason, you can't fit a 22.2mm stem into an accurately sized 22.2mm steerer.

The French standard was a 22.0mm steerer which took a 21.9mm stem. When Cinelli and 3ttt started producing "French" stems in the early 70's they were 22.0mm.

How's that work? Most steerers are not accurately sized and frequently a 22.1mm Nitto stem will fit in a 22.0mm French steerer without any modification.

Clean out all the gunk and rust out of the steerer. Run a hone through the upper half. Rolled up 100 grit emery cloth or sand paper will work too. Take a fine round or half round file an make a slight chamfer inside the top of the steerer. It will remove any burrs and make insertion smoother. Note, remove the top nut before doing any work inside the steerer. When you insert the stem don't tighten the top lock until you've tightened the stem. In some cases you may need to enlarge the hole in the top lock nut.

Nitto used to make 22.0mm (21.9mm) stems for French, Spanish and some Swiss bikes too. They've been discontinued for years.

French eBay has a lot of options for bars at 25 mm, and also has lots of stems that fit both the old 22 mm steerer tubes and 25.4 mm bars. I’ve bought a few on there and had them shipped to Seattle.
