Zipp 303 XPLR SW Carbon Wheelset

Zipp’s fastest gravel race wheel. The 303 XPLR SW was built around modern gravel tyres (38–50 mm) to reduce rolling resistance, vibration losses and drag at real race speeds. A 54 mm-deep rim pairs with an ultra-wide 32 mm internal bed to support low pressures (often <30 psi) without tyre squirm, while a 77% thicker hookless rim edge helps ward off pinch flats. According to Zipp testing, the tyre–rim system delivers ~5 W of aero advantage vs a leading competitor. Total System Efficiency meets gravel—go faster with more control.

Why you’ll love it
