Zipp 303 S Tubeless Carbon Disc-Brake Wheels

What Makes the Zipp 303 S the Versatile Speed Wheel?

The Zipp 303 S Tubeless Carbon Disc Brake Wheels bring the legendary 303 platform into the modern era of wider rims, tubeless capability, and disc brakes, built for today's versatile road bikes that perform equally well on pavement and rough surfaces. With a 45mm rim depth and a significantly wider internal width than previous 303 iterations, these wheels provide improved tire integration, lower rolling resistance, and better ride quality in every measurable way. The UD Carbon Hookless Rim with its smooth matte finish is tubeless-only, engineered to work specifically with tubeless tires for the aerodynamic and ride quality benefits that clinchers cannot match.

Laced to the proven 176D hub, the 303 S delivers smooth, durable performance for road cyclists who want race-ready speed across varied terrain. Compatible with 12x100mm front and 12x142mm rear thru-axle standards, and available in SRAM XDR and Shimano/SRAM 10/11-speed rear freehub options, these wheels cover the broadest range of modern disc road drivetrains. Sold individually as front or rear, they build cleanly into a complete race or training wheelset for riders who want Zipp carbon without moving to the NSW tier.
