ZIPP Coppia Ruote 303 XPLR S Tubeless Ready XDR B1 12mm

The Zipp 303 XPLR S is a carbon wheelset specifically designed for high-performance gravel riding. The wide 54 mm-deep rim, with a 32 mm internal width, is designed to work with wider gravel tires, improving aerodynamic efficiency, comfort and rolling performance on unpaved surfaces.

The Hookless / Tubeless Straight Side (TSS) rim design is intended for use with approved tubeless tires, while the carbon construction and Zipp 76D/176D hubs provide an excellent balance of weight, durability and performance.

The wheelset includes front and rear wheels, both featuring 24 Sapim CX-Sprint spokes and 12 mm thru-axle compatibility.
