Zipp’s legendary speed weapon, the
In developing the original 303 wheels, Zipp discovered that a wider rim increases lateral stiffness for sprinting and cornering while also providing greater vertical compliance for greater control, comfort and durability. That wider rim profile led ZIPP to develop our Firecrest technology, which revolutionized aerodynamic efficiency and stability for carbon wheels. The proprietary Firecrest rim shape optimizes the aerodynamic profile of the front half and - here's the revolutionary part - the back half of the wheel. Firecrest moves the wheel's center of pressure to be more in line with the steering axis for stability in even the stiffest crosswinds. All of that innovation along with the precision control of disc braking gives you a wheel that's as smooth as it is tough.
Zipp’s Sawtooth dimple design consists of 12 nodes that are specifically clocked to start aerodynamic shearing at a rate of 50hz at a rider speed of 20mph. Sawtooth accomplishes this by inducing small sheet vortices that shed at a low magnitude, but at a higher natural frequency, thus decreasing the laminar bubble effect on the aerodynamically shielded side of the rim’s profile to further reduce high yaw drag and improve crosswind stability.
The industry leading silicon carbide Showstopper brake track continues to evolve and improve, providing unmatched stopping power and modulation regardless of weather conditions or the length of the descent.
