Does anybody know of any good brand road bikes for around $300. I've looked around at my LBS and haven't had much luck. The only used bikes I've found have been 60cm + and I need around a 54cm. I don't want a Wal-mart special though. And another question, whats the difference between the cheap Schwinns at wal-mart and stores like that and the ones like the Le Tour you see at bike shops?
