Neu gibt es das wohl nicht mehr, franz. Innenlager sind ein schwieriges Thema. Du kannst mal hier bei Sheldon Brown nachlesen:
http://www.sheldonbrown.com/velos.html und dann über seine Linkliste Shops finden, die sich auf klassische Teile spezialisiert haben. Die meisten kommen aus den USA, aber es gibt auch einen in England, dessen Namen ich grad nicht parat habe.
Sheldon hat dafür einen guten Trick auf Lager:
"French-thread bottom bracket cups use 35mm x 1mm threads. They are getting hard to find. If you have a French bicycle with sound bottom bracket cups, you may want to re-use them, even if you wind up changing the axle. Since French bottom brackets are normally the usual 68mm width, British/I.S.O. bottom bracket axles will sometimes work.
French bottom bracket cups usually have thinner walls than Japanese ones, so the bearing ridges on the spindles are farther apart. If you use a standard Japanese spindle, the adjustable cup won't be able to screw in far enough to snug up the bearings, or if it does, it will sink into the bottom bracket shell so that you won't be able to install the lockring.
The good news is that a Japanese spindle made for an Italian size (70 mm) bottom bracket will usually fit! In the Sugino marking system, these are the spindles that are marked with a "5" code. Spindles for 68 mm bbs have codes beginning with 3. This trick often makes it possible to upgrade an older bike from cotterd to cotterless cranks at a reasonable cost.
Cartridge bottom brackets are not generally available in French thread, although Phil Wood retaining rings are avaialable in French size. Phil Wood rings work with both Phil Wood bottom brackets and
Shimano UN72 units.
French-thread bottom brackets, like Italian, use regular right threading on both sides. This means that the fixed cup will have a tendency to loosen up in use. The best prevention is to make sure it is really tight. In some cases, a thread adhesive may even be called for.
Some French bicycles, notably many Motobécane models, used Swiss thread bottom brackets. These have the same thread and diameter as French, but use a left thread for the fixed cup. This makes life interesting when you need to remove the fixed cup and don't know which way to turn it. Good luck.
Newer french bicycles commonly use Italian or British/I.S.O. bottom brackets."
