Description  

Zipp 303 Firecrest TSE Disc Brake Carbon Clincher A1 Tubeless Rear Wheel (SRAM XDR)

The Zipp 303 Firecrest TSE Rear Wheel delivers speed through efficiency, designed specifically for modern road cycling across variable terrain. By focusing on real-world performance rather than lab simulations alone, it achieves reduced drag, lower rolling resistance, and a smoother ride over imperfect surfaces.

Every detail of the wheel’s construction contributes to performance in practical riding scenarios. The 40mm rim depth balances aerodynamic advantage with low weight, while the 25mm internal rim width supports wider tyres at lower pressures for improved comfort and reduced rider fatigue. Zipp’s TSE (Total System Efficiency) approach addresses the four key energy losses in cycling—wind resistance, rolling resistance, weight and durability, and vibration—bringing them together in one efficient system. At its core, the German-designed ZR1 DB hub ensures fast engagement and long-term durability, enhancing responsiveness and control on demanding rides.
