The Zipp 303 XPLR S Gravel Rear Wheel is a top-tier performance upgrade built specifically for gravel riders seeking speed, durability, and value. Borrowing innovations from Zipp’s premium gravel line, this wheel delivers race-ready performance at a more accessible price. Engineered for speed across mixed terrain, it features a mega-wide 32mm internal rim width and a 54mm depth, offering increased air volume for reduced rolling resistance and improved tire stability. The hookless carbon rim seamlessly integrates with approved tubeless gravel tires, such as the Goodyear XPLR Slick and Inter, for maximum aerodynamic efficiency and a smoother ride.

Zipp’s Total System Efficiency (TSE) is the driving philosophy behind the 303 XPLR S, specifically addressing the challenges of gravel riding—rough surfaces, rolling resistance, and traction loss. The wide rim profile enables the use of lower tire pressures (under 30 psi), which minimizes vibration and maximizes grip in corners and climbs. Despite its bold dimensions, the wheel remains lightweight, helping riders maintain speed and reduce fatigue over long distances. The symmetrical rim design and UD fiber finish combine strength and aesthetics, while brass Sapim Secure-Loc nipples add long-term durability to this high-performance package.

At the hub, the 303 XPLR S Rear Wheel features a 176 DB hub with Center Lock disc compatibility and ships with 12x142mm thru-axle end caps. It’s available with SRAM XDR or SRAM/Shimano Road driver bodies, and its 24 CX-Sprint spokes in a 2-cross pattern ensure consistent power transfer and stability. With a maximum tire pressure of 50 psi and a system weight limit of 298 lbs, it’s built to handle your toughest gravel adventures—backed by a lifetime warranty.
