work on a smooth spin and high rpms and you can go fast. before spending most (or, well...all) of my time on a fixed gear, i spent a lot of time on a geared road bike with a cycle computer. or a speedometer, you could say...that was almost all i used it for. anyway, i chose one gear on that bike and stayed with that. it was 39/17. at first i was either slower or bouncing around in the saddle, but after working on the spin and getting to, i dunno 120 rpm (that's what, 3 turns a second, right?) and doing that smoothly, i could get up to ~25 mph, sometimes up to ~30 mph.

it could be good for you.
