I just bought a campy super record pista crankset (nos and dirty cheap)... well, half of it, the drive side. the only problem is that the length is 177.5 (??). so I've been looking for a crank arm but can only find a 175 or a 180. if I used the 175 would my leg fall off or something? would I drift to the left when I pedal?
has anyone tried this? how did it work out?
