I have an old Italian track frame for which I'd like to install a Campy pista bottom bracket. While the frame is circa 1950's, I will be using some 70's Nuovo Record bits, such as headset, bottom bracket, hubs and drivetrain.
I have some Italian threaded "thin walled" Nuovo Record cups.
Where the "strada" and "pista" versions identical? Am I correct in thinking that the only difference the bottom brackets of the era was the spindle? Same size bearings?
Assuming that is, in fact, the case I ought to be able to use a 70-P-120 spindle and be on my way, right? Were these always the same length? 109mm? Or should I be looking for something more specific?
