Zipp | 303 XPLR SW Carbon Wheelset

Go wider, run lower pressures, and keep your speed when the gravel gets rough.

The Zipp 303 XPLR SW is a high-performance carbon gravel wheelset designed for riders pursuing speed across demanding gravel terrain. Its wide 32mm internal rim creates greater tire air volume, allowing lower pressures for improved grip, traction, and vibration control.

The 54mm-deep hookless rim is specifically engineered around approved gravel racing tires, creating a seamless tire-to-rim transition for aerodynamic efficiency. Despite its wide profile, the 303 XPLR SW remains lightweight at an estimated 1,452 g, helping maintain speed and efficiency on long gravel rides.

Tubeless tires only. The Zipp 303 XPLR SW is compatible only with approved tires. Maximum tire pressure is 50 psi / 3.45 bar. Disc brake with Center Lock compatibility. Maximum recommended system weight is 298 lb / 135 kg.
