Just saw these on Zipp's website. They're out of stock right now so I've got some Vittoria Corsa Evo CX's coming for the new wheels, but I was curious if anyone had used these. They claim an additional 1-3 watt aerodynamic benefit with the dimpled tread, and they're pretty freakishly light at 232g.
Anyone tried them? There's a clincher version too that weighs in at 178g.
