Zipp 303 Firecrest® Carbon Clincher Rearwheel

Zipp’s 303 Firecrest Carbon Clincher is an all-around wheelset in every way. It’s rich in heritage yet loaded with innovations. It’s as adept in the mountains as it is on rolling hills, windswept farm lanes, or ferocious field sprints.

Fast, light and versatile wheels: the 303 Firecrest® Carbon Clincher from Zipp

Every Firecrest rim is designed and made by hand in Indianapolis. Zipp’s original 303 Tubular made history by becoming the first carbon wheelset to win cycling’s two most famous Cobbled Classics, Paris-Roubaix and the Tour of Flanders. Its wider rim provided extra durability, and improved aerodynamics. That wider rim also led to the development of our revolutionary Firecrest® technology.

At the center of these wheels is the pro-proven 77/177 hubset. Its optimized flange geometry and spoke hole attachment pattern is paired with Sapim® CX Sprint spokes to optimize torsional and lateral stiffness and robustness. Each wheel includes a quick-release skewer with a wide, more ergonomic handle to provide more leverage for opening and closing. When closed, the lever contours neatly with the frame. And at just 1,480grams, it’s light enough to dance up the steepest gradients with ease as a go-to all-around wheelset.

The Firecrest rim shape optimizes the aerodynamic profile of both the front 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. Exposed spoke nipples sit in the aerodynamic shadow of the rims, keeping serviceability simple without compromising speed.

Heavy continuous braking on carbon surfaces can cause spikes in rim temperature and tire pressure that impact performance and handling – especially with clincher tires. To solve this challenge, the composites supplier created a heat-resistant resin exclusively for Zipp. This technology improves heat dissipation so substantially that our Carbon Clinchers have never had a heat-related failure.

With the proprietary Firecrest rim shape in our 202, 303, 404 and 808 Firecrest wheels, Zipp wheels make a bigger difference in more ways than ever. Not only is Firecrest more aerodynamic than any other rim design, it improves handling in crosswinds and overall ride quality. 

ABLC™ (Aerodynamic Boundary Layer Control) 
Advanced Boundary Layer Control (ABLC) refers to the patented and instantly recognizable dimpled pattern found on all of our carbon rims. ABLC smoothes airflow across the rim's surface and is tailored to every model from the 202 to the Super-9 Disc. The third-generation of ABLC has up to four times more dimples than before.


Showstopper™ is a complimenting pairing of a directional, molded-in, texture with silicon carbide particles suspended in the surface resin.
