Zipp Am 303 Xplr Sw Cl Disc Tubeless Gravel Rear Wheel Silver 12 x 142 mm / Shimano/Sram HG

The Zipp 303 XPLR Disc Center Lock 12x142 mm front wheel is the fastest in gravel, thanks to its mega-wide rim that integrates perfectly with tyres approved for gravel racing.* Most gravel wheels are modified versions of existing road wheels, focusing on stiffness and lightness. Zipp takes a different approach. On gravel, resistance and vibrations from bumpy surfaces create a barrier that slows cyclists down. To combat this, Zipp applied Total System Efficiency specifically to the challenges of gravel. The wide profile increases air volume, allowing for lower tyre pressures without twisting. This means surface vibrations are mitigated while maintaining grip in corners or traction on climbs. The rim profile also creates a seamless transition with gravel tyres for unparalleled aerodynamic efficiency on gravel. And although the 303 XPLR SW is built large, it remains lightweight to keep you fast and fresh during those long and satisfying days in the saddle.
