ZIPP 303 Firecrest® Carbon Tubeless Wheelset

The Zipp 303 Firecrest® Carbon Tubeless wheelset is an all-round wheelset with 19 mm wide and 45 mm deep rims that allow for tubeless and are designed for minimal drag.

Through the pioneering use of software to analyse numerical fluid mechanics and the power of a supercomputer, Zipp is able to understand exactly what makes wheels go fast. Zipp then tests the most promising rim shapes in the wind tunnel and on the road. This process led to the creation of Firecrest rim technology, which allows the wheel’s airflow and centre of gravity to be controlled more effectively, resulting in better aerodynamics, better handling in crosswinds and an overall better cycling experience.

ABLC SawTooth™
This patented rim shape achieves what conventional aero wheels cannot: it simultaneously reduces aerodynamic drag and lateral wind forces, providing the ultimate AeroBalance™. In addition, the ABLC recesses ensure improved air flow. The result is lower aerodynamic drag and reduced lateral wind forces at any angle of attack. This is important because the steeper the wind angle, the larger the influence on the handling of the bike.

Showstopper™
Showstopper technology uses an encapsulated brake track with silicone carbide (SiC) surface for maximum braking performance when wet. The result is a braking performance that is in no way inferior to an aluminium rim, even in torrential rain. Showstopper technology offers more braking power when wet than any other carbon wheel.
