The Zipp 303 Firecrest Carbon Clincher has become a default choice for those seeking a truly top-end wheel because it does so many things well. By now everybody is familiar with the Firecrest rim shape that increases aerodynamics, stability in crosswinds, brake performance, tire performance and strength all at the same time. Black rim decals are borderless, thinner and lighter. But the most compelling reason to get the Zipp 303 is its incredibly low 685 gram weight for the front or 1540 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, Zipp has refined its venerable 88 hub set with a reshaped hub body and super smooth Swiss bearings.
The Zipp 303 Firecrest has a 250 pound rider weight limit and a 125psi tire pressure limit
