Greetings Folks,
I'm just going to add to the "data base" for Peugeot geometry: I no longer have my 1974 but it measured 23" (58cm with my tape measure) seat tube, with a top tube just slightly shorter (57cm); the seat tube angle was 72o and the head tube angle was 74o.
I also have a late 60's PX-10 as well as a '77 PY-10 and an early 80's Super Competition, none of which have been measured (by me). I'll do that sometime in the near future........
Cheers,
