I have reviewed the Campy timeline and am still looking for some insight on when the thicker walled, crud reversal rifling BB cups where introduced. And were these also used on Pista BB sets?
Last question, sort of OT, but not. Has anyone tried to use a newer Campy cartridge BB (early mid 90's) with a on topic Pista crank arms? As I line things up it looks like the spindle length might work (using a road cartridge BB for a Pista application) but I haven't tried it on a frame and haven't tested the flat angles.
