SS bikes are easier to maintain which is an advantage and also just kinda cool. I've done a bit of SS MTB in my day which is fun but only fixed on the road. I ride fixed (track and road), free (road and mtb) and have pretty much 0 interest in riding SS freewheel'd on the road like [MENTION=418438]TimothyH[/MENTION]. I'd just take a road bike instead.

You were fast tonight on your bike b/c you pedaled harder. Do you have a power meter? At any rate it doesn't matter, and if riding SS makes you wanna go harder, that's a good thing IMO. Cheers!
