6' 1" and was riding a 56 cervelo. most recently got a 08 Orca and switched to 57 only because Orbea gaps out from 54 to 57cm. I had a 58 specialized and It felt too big. I'm all legs , like a frog. the 57 fits me to perfection. a little more relaxed. the Cervelo was set up very aggressive with steep angle on the stem and had some serious drop from saddle to bars.
