I think the first generation Competitions you describe first began to appear on PX-10's and equivalent French bikes in the US market in the early/mid 70's, probably sometime from 1973 to 1975. They did look a lot like Racers, except I think even the first Competitions had a different straddle cable from Racers. Not really a good change in my opinion, as one could cut off a frayed brake cable and use it as a replacement for a Racer straddle cable, which I always found rather handy.

I do not mean the later Competitions with the different little trapezoid sticker saying Competition but the ones that look exactly like racers except they say Competition. Both my blue PXs have Dural Forged. One is a steel crank model and the other has the Stronglight 57(?)
Am I correct that Lambert Carnaksets have a 22mm pullong thread rather than the 223mm found on true TAs?
Thank you as always,
