Zipp 303 Firecrest Carbon Clincher V3 Road Wheel - Rear
The Zipp 303 was the first carbon wheel to win cycling's two most famous Cobbled Classics, Paris-Roubaix and the Tour of Flanders. Now, it's been completely redesigned with Firecrest shaping and a 28.5mm max rim width for extra durability and improved aerodynamics in unforgiving conditions. The Firecrest rim shape improves stability by moving the wheel's center of pressure to sit almost directly over the steering axis, where wind-induced steering torque has a minimal effect. As a result, its 45mm rim profile combines the wind-cheating advantage you'd expect with the crosswind stability of a box-section rim. The Firecrest platform also increases lateral stiffness for sprinting and cornering, while offering greater vertical compliance for more control, comfort and durability on rough surfaces.
The 77/177 hubset brings improved stiffness and durability over the hubset found on the previous generation of hubs, with wider flanges and a bigger axle. There's also no longer a need to set a bearing preload, and the bearings are also better protected from the elements, which means less wear and maintenance. A new improved quick release skewer also improves wheels retention and a more ergonomic lever for easier use.
