... besides fixed bb cups and left crank arm pedal threads.

did campagnolo ever use reverse threading in bb spindles for crank bolts?

i remember reading something ...

anyway, i can't remove a right (ds) crank bolt from a late '70s campy bb spindle, and am hoping i'm not overlooking the obvious. the bolt takes a 6mm allen wrench, which makes even more difficult.

maybe pb blaster?
