I have a Cannondale CAAD9 with Tiagra. I also have the triple crank which is good for the hills in Western PA. I am 6' 2" 230lbs. I have about 500 miles on it, and no problem with wheels. I ride a 63cm because I have a long upper body. As everyone else says make sure it fits. I have a montain bike that doesn't fit, and it hurts to ride it for any lenght of time.
