I'm trying to confirm required BB length for my 70's Dura Ace track cranks to give me a 42mm chainline. I fitted the cranks to a BB of known length (103mm on my Fuji - both JIS tapers?) and amazingly this gave a 42mm chainline. So, i'm assuming I can go with say a Sugino 103mm on the other bike I intend fitting the cranks to. I see from the transmission database most DA cranks are running 107mm BB's so I am assuming this applies to later cranks?
If anyone can sense check what I've done please ...........
