As for the Zipp website, I didn't see anything about the torroidal shape itself contributing to ride quality? Only that their VCLC technology in the carbon laminate is supposed to reduce vibrations. Of course that website also claims that "champions everywhere ride Zipp". I'm sure that there are champions out there somewhere who don't. ;)[/reply]

Actually, I couldn't find anything on Zipp's website to back me up on this either. I just knew that I felt it. But Josh at Zipp has a good post in this thread on the issue, along with some other interesting stuff.
