My DH and I just finished our quest for the new tri bike. Looked at Kuota, QR, Felt and Cervelo. Getting rid of the low end QR Tequilo (to kill your back) and into the P2C with minor upgrades. The technology in the cervelos now is grade A. My LBS guy who we love actually took one into a wind tunnel. His words were it almost actually has negative resistance(makes you FASTER!!!!!). The ROO is a very aggressive, stiff frame and the cervelo has many fit and adjustment options. We are taking the DA P2C, red is DA and $500 more. Boys have to have red. New DA crank to replace the kind of crappy FSA crank. Zipp 404 wheels, and T2 bar ends. That is the machine! Really impressed with cervelo. Take a look at their website and read all the fit options and research. They are into the aerodynamics of it all.
