The Zipp 303 XPLR SW is a big wheelset for your biggest gravel goals. It's the fastest on gravel, thanks to its mega-wide rim that integrates seamlessly with approved gravel racing tires. Unlike most gravel wheels, which are modified versions of existing road wheels, the Zipp 303 XPLR SW is designed to combat the resistance and vibrations from bumpy surfaces that slow riders down. The wide profile increases air volume, allowing for lower tire pressures without squirm, which 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 SW is built big, it's still lightweight to keep you fast and fresh for those long, fulfilling days in the saddle. The Zipp 303 XPLR SW is suitable for both men and women, and is available in a range of sizes. It features a black color and is designed for unisex use.
