ZIPP 303 XPLR S CARBON DISC TUBELESS CL REAR WHEEL

The Zipp 303 XPLR S is big upgrade in speed for gravel riders without a big price tag. 

This wheelset borrows key innovations from Zipp's premium wide gravel wheelset, it is affordable and robust for discerning gravel riders. This wheelset is the fastest on gravel, thanks to its mega-wide rim that integrates seamlessly with approved gravel racing tyres.

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 tyre 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 tyre, the tyre-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 wheel is optimized for use with the Goodyear XPLR Slick and Goodyear XPLR Inter, both tyres designed in partnership with Zipp.
