The Mercier Kilo TT is indeed a sweet bike. The only complaint I had was that it came witha bent wheel, but the seller sprtymama (who is also bikechica and associated with bikesdirect.com from what I can tell) took care of it right away and free of charge for me. Couldn't be happier. Nice light bike too. Only things I've changed are the saddle and bars (Arami gel around and nashbar bullhorns). Eventually I'll trade out the ultra durable but heavy 36x spoke wheels it came with for something nicer. But for the $350 I paid, I couldn't be happier. Even looks like a 1/8 track chain on it, although I haven't measured it to be sure.
