Bicycle rear wheel 303 XPLR SW HG

With its ultra-wide and tall rim, ideally suited for gravel tyres, the 303 XPLR SW wheel is the fastest gravel wheel ever produced by Zipp. Current gravel wheels are slightly modified versions of existing road wheels, focused on stiffness and lightweight. Zipp has taken a different approach by concentrating solely on speed. In gravel riding, the main obstacles to speed are rolling resistance, losses due to vibrations on rough surfaces, and wind. To tackle these, Zipp has applied its Total System Efficiency design philosophy to the challenges of gravel. The 303 XPLR SW is a gravel wheel designed for speed, following a new approach: starting with the ideal gravel tyre and designing a wheel around the tyre.
