Description
This wheelset is the fastest on gravel, thanks to its mega-wide rim that integrates seamlessly with approved gravel racing tires. In gravel, resistance and vibrations from bumpy surfaces create a barrier that slows riders down. To combat this, Zipp applied Total System Efficiency specifically to the challenges of gravel. The wide profile increases air volume, allowing for lower tire pressures without squirm.
The 303 XPLR’s deeper and wider rim design means better aero performance. Ultra-wide internal profile for decreased rolling resistance.
