I like my 303 FC tubies. Use them for racing primarily. Stiff enough, they are very stable when the winds blow compared to regular deep v wheels, and the ride quality is really good when hitting some bumps they way the side flexes.
The C35 are great wheels also. Many big pro teams using them.
If you want the stiffest wheel possibl, that would likely be the Mavic Cosmic Carbone Ultimate. All carbon. Same weight as 303FCs. Liquigas uses them. Sagan surely can put a beat down on those wheels, as proof they are versatile and stiff.
Fitment, have no idea. But, Specialized Venge frames have issues with rubbing on the chain stays due to the wider rim being produced after they did their design/molds. Haven't heard of Cervelo having any issues. That was the 303FC specifically, the 404 FC, due to a slightly taller/different profile, didn't have that issue on the Venge.
Can't recall if I've seen people with FCs on any Cervelos...surely people are running them??
What do you want specifically out of a wheel? Aero? Stiff? The new HED Stingers, Bontrager D3, Zipp FC are all in the new Aero category/toroidal (sp?) shape.
Stiffness, not as aero, I would get the Cosmic Carbone Ultimate personally. But for my needs, the 303FCs can really do it all. And the price of the 303FC tubies you can get for $1700-1800.
I happened to find a good deal, not retail mind you, on brand new 303 FCs off the bay with Vittoria Corsa CX 320tpi tubies mounted. $1800 shipped to my door. Will Zipp warranty them? Who knows. I didn't buy them retail, but then again, don't care about a warranty. Nobody is going to cover a crashed frame/wheel, only flaws/manufacturing defects.
