Incidentally, my retro project is a Peugeot CFX-10 frame (frame only model of Peugeots PX-10) built in 1980 - all the advice is against going with a french bike as your first project, but I'm not good at taking (some) advice. I'm enjoying the mental challenge presented by french standards (derailleur hanger, stem/headset, the BB shell (is it french threaded or swiss threaded?), turns out it is french threaded (hurrah) but someone before me machined a bevelled edge to take an old threadless which messed of the first few threads on either side. I'm shortly moving onto the physical challenges of building (cannot start until after Christmas as the frame is a Christmas present from my wife - she thinks a project will slow me down with buying more bikes)
