Is this the 2008 bike?
I have a Roubaix RC 2008, which is identical apart from the drivetrain (ultegra) and wheels - which I've upgraded anyway.
They have the same frame and fork, which is comfy and pretty solid when you're pushing it. My only niggle is fork could be a bit more forgiving (in road buzz terms). Climbing is okay (there are lighter bikes out there - though probably at a higher price), as is descending. But it feels most at home going fast on flat roads, much better than other bikes I've tried.
Saddle is cr@p though!
BTW: I got mine from
