Oh thanks for the great info. I just got off the phone with my dealer who also offered to build it up with durace for me if I prefer.

Its a cervelo R3. He is having trouble getting rid of the2008 XS frame cuz it has 650c wheels, so is willing to be very accomodating, while that is exactly the frame I have been drooling over, but didn't want to pay full price for.......

As a shimano gal durace will feel more familiar.

I currently ride terrys with the 24" front wheel, and had been looking for a bike with a slack seat tube angle to accomodate my long femurs and 650c wheels to get me good handling without tco (I know this doesn't matter to some of you but it does to me). Soooooooooooooo, I am just sooooooooooooo tempted.
