I'm messing around with my first fixed-gear project and I want some vintage cranks. I found a set of Dura Ace 10-Pitch Track cranks and bottom bracket. They have no chain and no chain ring (I hear these are hot comodities). Could I put a different chain ring on them and run a different chain? Could I sub the bottom bracket for a current shimano bottom bracket with Italian threading and still get an ok chainline? Any help would be great! Thanks!
