Description
The Zipp 303 XPLR S B1 Rear Wheel is designed for gravel riders seeking a robust and affordable upgrade. It features a 700C (622 ISO) carbon rim with a 32mm internal width and 54mm depth, optimized for tubeless-ready gravel tires. The wheel’s wide profile increases air volume, allowing lower tire pressures to reduce vibrations and improve grip on rough terrain while maintaining aerodynamic efficiency.
This rear wheel includes a 12mm thru-axle with 142mm hub spacing and is compatible with SRAM XD-R cassettes. It uses Zipp 76D hubs with sealed cartridge carbon steel bearings and Sapim CX-Sprint spokes with aluminum nipples. The rim has a double-wall carbon construction and is designed for use with Zipp-approved tires, supporting maximum tire pressures up to 50 psi and the ability to run pressures below 30 psi.
Additional features include a Center-Lock disc brake interface and a Presta valve. The wheel has 24 spoke holes and comes in a dark gray and black carbon color scheme. No skewer is included.
