There are a lot of reason to buy the Zipp 303 Firecrest Carbon Clincher. By now everybody is familiar with the Firecrest rim shape that increases aerodynamics, stability in crosswinds, brake performance and strength all at the same time. The new "Beyond Black" version with a black hub, spokes and graphics take the 303 to the next level style-wise. But the most compelling reason to get the Zipp 303 is its incredibly low 818 gram weight for the rear or 1498 grams per pair helps make the dream of a 15-pound bike with Paris Roubaix strength a reality.

Firecrest's signature shaping is designed to optimize both halves of the wheel and balance the center of pressure. This creates a 45mm sectioned rim that is significantly faster than other deeper rims while handling crosswinds like a box-sectioned rim. Despite its ultra-light weight, the 303 is utterly dependable. In fact, the 303 is the first carbon wheel to win Paris-Roubaix and Tour of Flanders.

The new wheels retain all the small details that make Zipp wheels what they are. Exposed spoke nipples sit in the aerodynamic shadow of the rims, keeping serviceability simple without compromising speed. And Zipp's signature ABLC™ rim dimples squeeze every last second of performance possible. To complete the package, a Zipp 188 hub features a 17mm axle for high strength and super-round Swiss-made, stainless steel cartridge bearing for low friction. Shimano/Sram compatible - call for Campagnolo compatibility.
