As above: My much loved old hybrid commuter bike has now gone to the big scrapyard in the sky and I'm thinking of dabbling with single-speed for its replacement. Does anyone have experience of these? (either fixie or freewheel). I've read the pros and cons on the cycling boards and am not entirely convinced that I could do without gears to take the pain away when a bastard of a hill approaches but know that others swear by them. Just wondered if anyone had ditched the gears and either never looked back or hated it utterly?
