Zipp 303 S Tubeless Disc Brake Carbon Wheel Front

The Zipp 303 S Tubeless Disc Brake wheelset is built for cyclists who demand all-surface capability without sacrificing speed. Carrying on Zipps legendary Spring Classics performance, the 303 S combines a 45mm rim depth with a newly designed, wider profileperfect for todays fast, capable road and gravel bikes.

Wide Rim Innovation for Real-World Gains: With a 27mm external and 23mm internal rim width, the 303 S is optimized for 28mm tires but can handle widths up to 50mm. This allows for lower tire pressures, reducing rolling resistance and rider fatigue while enhancing grip and comfort across mixed terrain.

Aerodynamic and Tubeless-Ready Efficiency: Designed to be run tubeless, the 303 S improves aerodynamic performance and rolling efficiency. The wider rim shape boosts tire stability and minimizes drag, delivering a measurable power savings of up to 10% at 40kph compared to leading competitors.

Lightweight Strength with Proven Durability: Despite its aero-focused 45mm depth, the 303 S remains one of Zipps lightest wheelsets, making it suitable for climbing, racing, or fast gravel adventures. Its carbon construction ensures long-term strength without excess weight.

Available in front (12x100mm) and rear (12x142mm XDR) with center lock disc mounts, the 303 S is ready for modern drivetrains. Finished with Zipps updated graphics, this wheelset combines performance and aesthetics in one standout package.
