Converting a Double Chain-ring to a Single - Please Help
I have an old double-chainring crank set (Sugino Super Custom) that I want to use for my fixed-gear bike. I will be using the smaller chainring (42T), but I want to bring it from the inside of the spider arms to the outside. How can I do this and still retain a straight chain line?
So far, I don't have a bottom bracket installed in the frame, but should I bring the crank set (with the small chain ring on the outside of the spider arms) in to an LBS and let them figure which bottom bracket would be appropriate? Can the length of the bottom bracket be chosen to allow a straight chain line?
Any help will be appreciated, since I'm not familiar in this area!
