I've got a Peugeot Super Competition, and just realized that the stock spindle is probably ISO tapered, while my Sugino RD crank set is designed for a JIS taper. As far as I can determine, this frame is probably French or Swiss threaded, which means that, if it's Swiss threaded, I'm basically screwed. If it's French threaded, I have to buy a new French threaded bottom bracket with a JIS taper. Do Sugino or other companies make such a product?
