god, i hate pointing people to this site, because i'm worried these'll run out before i can afford to snatch up a pair, but, oh well....you gotta help a brotha out. i just used these to "fix" my girlfriend's bike, and i have nothing bad to say about these. http://www.bicyclewheels.com

the only "track" wheelset on there is what i'm talking about, and it's actually a flip-flop hub. fixed/free.
