Quick question for you Frenchie-philes.
I have an early 1970's PX-10 with Simplex dropout, from which I just removed the original (?) Simplex derailleur. The derailleurs will clean up nicely but I'm not in love with them.
I am wondering what alternatives would be appropriate. What would racers and racer-wannabes have hung on their PX-10s in 1974, if they didn't want the original Simplex for some reason?
I was kind of thinking Huret mechs might have found their way onto some of these bikes? Would that be too unoriginal? And - maybe more problematic - will Huret mechs fit on a Simplex dropout?
And about the shifters - I was thinking about starting the search for some Simplex retrofriction bar end shifters. Will those work with Huret changers? Will I need the demultiplicator, that I'll probably never find for an affordable price? And, same worry about appropriateness - in the early/mid 1970s, would bar ends ever have been used by racers?
