Zipp 303 XPLR SW wheels

The Zipp 303 XPLR SW wheels are big enough for your biggest off-road goals. How big? This wheel is one of the fastest on rough surfaces thanks to its extra-wide rim, which pairs perfectly with race-approved tires*. Most gravel wheels are modified versions of existing road wheels, focusing on stiffness and lightweight. Zipp takes a different approach. In gravel, resistance and vibrations from uneven surfaces create a barrier that slows cyclists down. To combat this issue, Zipp has applied Total System Efficiency specifically to the challenges of gravel. The wide profile increases air volume, allowing for lower tire pressure without vibrations occurring. This means that surface vibrations are dampened while maintaining cornering grip and climbing traction. The rim profile also creates a seamless transition with gravel tires, for unmatched aerodynamic efficiency on rough terrain. Although the 303 XPLR SW is built big, it is lightweight to keep you fast and fresh on long, rewarding days in the saddle.
