Description
303 FIRECREST | Carbon Clincher
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.
Optimized flange geometry and spoke hole attachment pattern with Sapim® CX Sprint spokes to optimize torsional and lateral stiffness and robustness.
Includes 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.
New robust hub platform with distinctive graphics. For those looking for a wider gear range, or tackling especially extreme terrain, a XD driver body for 177 is sold separately and easily installed to allow for more cassette options including a 10-42. The hubset is designed to swap driver bodies without re-dishing wheel.
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 1,625g, it’s light enough to climb up the steepest gradients with ease as a go-to all-around wheelset.
