Borrowing key innovations from Zipps premium gravel wheelset, it remains affordable and robust for discerning gravel riders. The 303 XPLR S is fast on gravel thanks to its mega-wide rim profile and utilizes Zipps Total System Efficiency specifically to the challenges of gravel. The wide profile rim increases air volume, allowing for lower tire pressures without squirm. That means riders can mitigate surface vibrations while maintaining grip when cornering or traction while climbing. The rim profile also creates a seamless transition with gravel tires for unsurpassed aero efficiency on gravel. And while the 303 XPLR S is built big, its light to keep you fast and fresh for those long, fulfilling days in the saddle.
