I don't know if it is too big...it might be. My last road bike, a Bianchi Volpe, was 6 cm smaller. The bars were never level with the seat (I have a 36" inseam, so my seat is really high) but it was much closer. Funny thing, a professional bike fitter told me that bike was too small. All of the frames I've test ridden lately are 60+cm, which doesn't give a lot of standover but does raise the bar relative to the seat. I have long legs and arms, but a short torso. I have pics of the bike at home, I'll post them tomorrow morning.
