The Zipp 303 Firecrest Carbon Clincher Front Wheel delivers everything you could ask for, including a heritage forged in the Spring Classics. At the center of the 303 Firecrest Carbon Clincher is the 77/177 hubset, an innovation that results in improved stiffness, durability, simplicity and versatility.
Zipp's Carbon Clincher technology preserves the aerodynamic advantages while adding thenience of a clincher tire. And it's light enough to climb up the steepest gradients with ease as a go-to all-around wheelset.
The Firecrest shaping optimizes the aerodynamic profile of bothont half and the back half of the wheel. In addition, Firecrest moves the center of pressure of the wheel backwards, giving the 45 mm-deep rim the crosswind stability a box-section rim. At the same time, the 26.4 mm-wide brake track (at center) allows the clincher tire to take on a wider, more stable shape without compromising rolling resistance. It's faster, simpler, and more stable.
Theheels 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 signature ABLC™ rim dimples squeeze every last second of performance possible.
