Tyre Type:

The Firecrest 303 Tubeless Disc is approved for the use with tubeless and Tubeless Ready tyres only, due to the hookless rims. Please make sure that the tyre manufacturer’s approval is given for hookless rims. An inner tube can be used with a tubeless/tubeless-ready tyre which is compatible with hookless rims. Follow the installation recommendations of the tyre manufacturer.

Features:

• new Zipp graphics for a speedy look
• versatile long distance wheelset for modern road bikes with tubeless and hookless rim profile

• ultra-wide 25 mm rim profile creates a better transition to the tyre for fast on and off-road performance
• 40 mm depth makes the wheel light and aerodynamic in every situation
• ZR1 DB hub (manufactured in Germany) with revised seal design for improved durability and faster response
• aluminium axles
• front can be converted to 9 x 100 mm quick release or 15 x 100 mm thru-axle (end caps sold separately)
• rear can be converted to 10 x 135 mm quick release (end caps sold separately)
• TyreWiz tyre pressure sensor sold separately

Technology:

Firecrest®
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.
