I have a '72 Schwinn Super Sport that I recently rescued from a basement where it has sat unused and certainly unloved for the last several decades. I decided that I was going to convert it to a single speed and try to eliminate some of the weight. I know that some of you will find this to be sacriledge but its the path I've chosen. What I need is a crank that looks right with that bike. I'm hoping y'all will have the answer. So what crank fits the bill. I also want to be able to use more modern pedals, clipless on one side and platform on the other.
