I'm 6'1.5" and am on a 58cm bike. My Madone's seat mast barely goes high enough for my legs though. I was also pro-fitted to the bike, and I'm confident with the guy who fitted me. Just as a heads up though, even though a bike may feel comfortable, it still may be the wrong size. I managed to ride across the country on a 62cm bike with a 130mm stem. I was setup for a guy who was 6'4", but it felt fine to me.
