Speed Gains at Lower Tire Pressures
The 303 XPLR rim design provides measurable speed gains by lowering your tire pressure more than with previous wheels. A rider going 32 kph on gravel riding 40mm wide tires saved about 8 watts at 28 psi (1.9 bar) compared with a more traditional gravel wheel with 40mm tires at 36 psi (2.5 bar).
Greater Aero Efficiency at Higher Speed
The 303 XPLR’s deeper and wider rim design means better aero performance. At average race speeds (about 29-36kph), Zipp internal testing found 2-watt savings from aero efficiency gains compared with a peer wheel. The advantage grew to 10 watts or more when speeds exceeded 53kph on descents and other fast sections.
The Zipp 303 XPLR S is big upgrade for gravel riders without a big price tag. This wheelset borrows key innovations from our premium wide gravel wheelset, it is affordable and robust for discerning gravel riders. 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. That means you 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, it’s light to keep you fast and fresh for those long, fulfilling days in the saddle. The Zipp 303 XPLR S is compatible only with approved tires.
