ZIPP 303 XPLR S DB CL WHEELSET

The Zipp 303 XPLR S gravel wheel is born for those who seek speed on mixed terrain without sacrificing robustness and control. The carbon rim with a tubeless ready hookless profile and ultra-wide internal channel is designed to work with very low pressures (even below 2.1 bar / 30 psi), reducing rolling resistance and improving comfort, traction, and stability on rough surfaces.

The rim's wide and deep profile integrates optimally with high-volume gravel tires, also improving aerodynamic efficiency at high speeds. This wheel applies Zipp's Total System Efficiency concept to gravel performance: less energy dispersion, greater smoothness, and more control, even on long and demanding routes.

The 76 / 176 DB hubs with Center Lock brake interface guarantee reliability and smoothness, while the construction with CX-Sprint spokes and brass nipples ensures stiffness, resistance, and durability over time. It is a solution designed for fast gravel, endurance races, and off-road adventures where performance and solidity must go hand in hand.
