Many thanks to Raoul and all who answered, for your suggestions. I was looking for French threaded pedals for my Peugeot PX 10 that were wider than the Lyotard 45's that came on the bike. I have a used pair of the Marcel Berthet platform pedals, but they are English threaded. Last night I had a brainstrom that the axles might be the same as the Lyotard 45's . I dissected the pedals, and sure enough they are identical. I switched axles (takes about an hour and a half, including toeclips, straps, etc.), and installed the now French threaded Marcel Berthet's on the Peugeot. When it stops raining in NYC I'll take it out for a ride. This information (interchangeability of the axles on the pedals) might be useful, since French threaded Berthet's are rare. Josh Berger
