I love commuting on the fixed gear. I have several to choose from. One thing I found that helped with the change back to a road bike is a different cassette. I was riding a standard cassette, I think it is like a 12 x28 or something like that, I replaced it with a 12x21 and man can I flat out fly now, and I'm not waiting for the bike to slow down to be able to engage, it's right there all the time. I still love the fixies, now I can ride the roadie and on the flats get 30+ miles and hour.
