I guess this topic would be better in some other forum.
Up for a DIY project? Check out this from that guy from Harris cyclery.
http://sheldonbrown.com/hercules.html I've never seen anyone else with a setup like this, either on the FGG or here in the photos thread. I was going to try it once when I had a real flip/flop hub, but the bike got jacked before I had a chance to get into it. Looks like a sick setup, would be fun to try if you like tinkering, and who doesn't have extra 5 or 6 speed freewheels around from old conversions? ANyway, just an idea.
