I have a track bike with 1983 vintage 165mm campy cranks and BB. I want to replace the crank arms with 170mm cranks and I was thinking of Sugino 75 because they are readily available, use 144 chainrings, and cheap. Plus doing so would allow me to keep the BB in place. Are these compatible? I have read the various threads here on BikeForums and I confess I am simply not able to extract an answer from them although I am sure it is there. So can somebody answer this question?
