Here's a lurker type question. If the inside chainring lips of a mid '70s Campy strada (144 bcd) crankarm were removed, would it have the same dimensions as an equivalent pista crankarm? i.e. could you use a pista bb and get appropriate alignment with a 120mm fixed rear hub mounted on a '70s era road bike with Campagnolo horizontal dropouts?
