303 S Carbon Disc Brake Wheel - Tubeless

What Our Gearhead® Experts Are Saying:

“The 303 S is the ultimate do-it-all carbon wheelset—fast on the road, stable in crosswinds, and perfect for wider tubeless tires. It’s one of the best performance-to-value upgrades out there.”

Zipp’s 303 S Carbon Disc Brake Wheelset redefines what an all-road carbon wheel can do. With a 45mm rim depth and 23mm internal width, it balances aerodynamic efficiency and crosswind stability with the comfort and traction of modern high-volume tires.

The hookless rim design not only saves weight but also enhances tire profile for reduced rolling resistance and more predictable handling in corners. Tubeless compatibility allows for lower pressures and fewer flats, while the 76/176 DB hubs and Sapim CX-Sprint spokes deliver a confident, responsive ride feel under power.

Engineered for everything from crits to gravel grinders, the 303 S is as efficient climbing switchbacks as it is blasting through wind-swept straights. It’s Zipp’s next chapter of speed—optimized for real-world performance, not just the podium.
