This near-levitation ability is owned to their unique Carbon Fiber Tubular Rims with a super-slim 32mm profile, which combine the best VCLC technology with our very own refinements to Inversion Composite Technology.

For 2008 we have redesigned the shape, increased the rim depth for additional aerodynamics, added dimples, increased the tire bed width, added internal nipples and improved the impact resistance by 28% through our Carbon Bridge™ technology.

With our proprietary resin formulation and construction methods developed just for the demands of climbing, we've been able to reduce the number of spokes (and their weight) without sacrificing strength. Accelerates and climbs like a fighter jet, lasers through cross winds, and descends just as shockingly fast.

Note: this wheel model is only available as a tubular and has a recommended maximum rider weight of 185lbs (85Kg). We offer PowerTap® and ceramic versions of this climbing wheelset. if you are looking for additional options consider the Zed2
