This. The stock wheels aren't bad but they're far front great. I have Fulcrum racing 5 + Conti GP 4 seasons on my CAAD8 and it's a noticeably better ride. CAAD10/Supersix has racier geometry, great bikes I'm sure but you may find it's not for you.

I have just put some Fulcrum 3's with Conti 4000's on my Specialized Comp/Race and that has made a load of difference too..
We are in the process of moving back to the UK so at the time of my next bike purchase (Septembe-rish) I will book a ride at evancycles perhaps a different model as well just to compare.
I did have trouble with my first road bike so may be a ride on a few might help sort a bike out..
