I would be surprised if a single speed were faster than a geared bike on mixed terrain. The net weight differences will be small, percwntage wise, whereas the gain in efficiency (maybe not the right word) when changing gearing needs will be large. Don't ask me for specific numbers!
Either way, it will be fun. Edwin -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
