Not a bad deal. The weels area GREAT upgrade and worth some cash in their own right. Does it fit is the biggest question you need to ask yourself. I have the CAAD10-3 (ultegra) and it cost me $1700, so that is a bit of a discount for the 9, and some will say it's a better bike (made in usa
).
I am 5'10"ish and ride the 54, but size is all about where your height is (legs, torso, etc.)
