best rebuild for this late 70s Olmo
this Olmo arrived with a mishmash of bits - Campagnolo GS derailleurs, Mafac brakes, nifty Campagnolo "FM (Moser)" pantoed shifters (see attached)...
I'd like to build it back up with something period appropriate and of best quality.
I was going to swap over some what I think are Nuovo Record bits from another bike except that those shifters are clamp-on whereas this Olmo requires braise-ons.
Q1. in the same era, would one have the choice, in the same gruppo, of clamp-on versus braise-on shifters, depending on how the frame was built?
Q2. in an ideal world, what would make best sense for this frame (I have quite a range of spare Campagnolo bits to work from.) if it was a recreational frame, maybe the GS setup would be most suitable and so I just have to find Campagnono brakes and brake levers.
Q3. I have a heck of a time distinguishing the various Campagolo models of that era. Would there have been a GS brake and lever different from a NR brake and lever? or would they have used the same Brakes and levers and just used different derailleurs?
