The Zipp 303 S Tubeless Disc Brake Wheelset is engineered to meet the needs of modern cyclists who demand a balance of versatility and speed. Building on its rich legacy of dominating the Spring Classics, the 303 S retains its all-terrain 45mm rim depth while introducing a wider internal width for enhanced performance and ride quality across various surfaces.
As road bikes evolve to tackle mixed terrain without sacrificing speed, the 303 S emerges as the ideal companion. Its new rim profile and design are tailored for disc-brake bikes, allowing riders to enjoy race-ready performance on smooth roads, gravel trails, and everything in between. The tubeless setup enables wide tyre compatibility and lower pressures, improving efficiency, comfort, and grip.
Among Zipp's lightest wheelsets, the 303 S is optimised for aerodynamics with 28mm tyres but is also capable of supporting gravel tyres up to 50mm wide. Borrowing advanced features from the high-end 303 Firecrest wheelset, the 303 S achieves speed gains by reducing wind resistance, rolling resistance, rider fatigue, and overall weight.
Key Innovations and Design
The heart of the 303 S is its innovative rim design. While maintaining the 45mm rim depth of its predecessor, the 302 Disc Brake, the 303 S features a 2mm wider rim width (27mm external) and a 7mm wider tyre bed (23mm internal). This design ensures optimal performance with a 28mm tyre, allowing for lower tyre pressures to reduce rolling resistance and improve comfort. According to Zipp’s testing, the 303 S achieves a 10% watt savings compared to top competitors when riding at 40kph on smooth roads with 28mm tyres.
