The Zipp 303 XPLR S rear wheel delivers a big gravel upgrade without the big price tag, pairing a mega-wide, fast-rolling rim with the drive-side stiffness to put power down on rough, loose ground. It applies Zipp's Total System Efficiency thinking to the specific demands of gravel riding.

The ultra-wide 32mm internal rim boosts tyre air volume so you can run pressures under 30psi without squirm — cutting the surface vibrations that slow you down, while adding grip and climbing traction. The wide, 54mm-deep profile blends smoothly into approved gravel tyres for real aero efficiency, and despite being built big it stays light to keep you fresh on long days.

It's a hookless, tubeless carbon rim laced to Zipp's 176 rear hub with 36 points of engagement, available with a SRAM/Shimano HG or SRAM XDR freehub. Please note the 303 XPLR is compatible only with Zipp-approved tyres. Available in Dark Grey or White, with Zipp's lifetime warranty.
