Not a picture post, but a quick question I'm hoping someone can answer. I'm knee deep in my 53 Schwinn Panther Klunker Build, and I'm hoping to go multi-speed. The best option to me looks like an SA Drum Brake with a 5 or 7 speed freewheel. I'd prefer 5, as I have a schwinn 5 speed freewheel. Does anybody know if a 5 speed freewheel will work on the X-RD? It says for 7 speed, but I vaguely remember 5 and 7 speed freewheels being roughly the same size. Any help is appreciated!
