ZIPP 303 XPLR SW Carbon Tubeless Gravel Disc Wheelset

Go BIG. Go Gravel.

The 303 XPLR SW is Zipp's fastest gravel wheel ever, thanks to its mega-wide and deep rim that integrates seamlessly with gravel tires. The 303 XPLR SW is a speed-focused gravel wheel designed with a new approach: Start with the perfect gravel tire and design a wheel around it. 

Current gravel wheels are slightly modified versions of existing road wheels, focusing on high stiffness and low weight. Zipp takes a different approach, solely with speed in mind. In gravel, rolling resistance and vibration loss from rough surfaces, and wind are significant barriers to speed. To combat this, Zipp applied its Total System Efficiency design philosophy specifically to the challenges of gravel.

Typical tire widths for gravel racing range from 38-50mm with varying tread patterns. Current gravel wheels have an external rim width of 28-30mm, which creates an aerodynamic mismatch when you use a 40mm+ gravel tire. With that narrower rim and wider tire, the tire-wheel interface looks more like the bulge of a lightbulb than the ideal seamless airfoil cross-section. According to Zipp testing, the efficient pairing of wheel and gravel tire of the 303 XPLR S design provides a 5-watt aerodynamic advantage over a leading competitor.

Note: This wheelset is optimized for use with the Goodyear XPLR Slick and Goodyear XPLR Inter, both tires designed in partnership with Zipp.
