If perfection is the standard, then the 303 Firecrest wheelset 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 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® platform, and now the revolution continues with the inclusion of the 77/177 hubset - best-in-class durability and improved bearing protection with no pre-load adjustment needed.
Zipp's Carbon Clincher technology preserves the aerodynamic advantages of the 303 Firecrest's tubular brother, while adding the convenience of a clincher tire. And at just 1,645g, 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 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.
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.
Newly designed quick-release skewers with a wider more ergonomic handle to provide more leverage for opening and closing. When closed, lever contours neatly with the frame.
The wide profile of the 303 Firecrest is crucial to Zipp's revolutionary Firecrest technology used to create wheels with superior aerodynamics as well as improved stability and handling.
The rear 303 Firecrest, however, may present some fitment issues for a small number of road and triathlon frames. The clearance between the chainstay and the rim may not be adequate to avoid contact between each other when ridden under load.
Below is a list of known frames that may present this issue.
- 2012 Specialized Tarmac SL4
- Specialized S-Works McLaren Venge
