I am 6' 7" 250 lbs and I just bought a 2010 63cm CAAD9 5 this spring. I test rode this bike and a Trek 2.something in a compatible (size 64cm I think). I have found my new bike is able to handle anything I can throw at it. I found the Trek frame to be mushy in comparison to the CAAD. I know your post didn't ask to compare to the Trek, but I am just offering my experience. As a clyde, I wouldn't know what more I would want from the CAAD9 except for maybe a 65 or 67cm frame.
