Introducing the Zipp 303 S Tubeless Disc Brake wheelset - the ultimate choice for today's cyclists seeking unrivaled versatility and unmatched speed. Building upon its illustrious legacy of conquering the Spring Classics, this exceptional wheelset retains the highly sought-after 45mm rim depth while incorporating a significantly wider internal width. The result is a remarkable enhancement in performance and ride quality across all measurable aspects.

In an era where road bikes are more adaptable than ever to varying surfaces, the 303 S revolutionizes rider experience with its innovative rim profile and design tailored to the demands of this new breed of bike. Specifically engineered for tubeless disc-brake bikes, it empowers riders to unleash race-ready speeds on any terrain by allowing the use of wide tires at lower pressures. Astonishingly lightweight, this wheelset is optimized for exceptional aerodynamic performance with a 28mm tire, while remaining capable of accommodating gravel tires up to 50mm wide.

The 303 S draws inspiration from the esteemed 303 Firecrest Tubeless Disc-brake wheelset, adopting design principles that enhance efficiency to maximize speed. By reducing wind resistance, rolling resistance, rider fatigue, and weight, it offers an unparalleled advantage. At the heart of this breakthrough lies the rim design of the 303 S Series. It maintains the 45mm rim depth of its predecessor, the 302 Disc brake, while widening the rim by 2mm to 27mm and expanding the tire bed by a substantial 7mm to 23mm. This unique rim platform delivers optimal performance with a 28mm tire, enabling a lower tire pressure that minimizes rolling resistance and ensures a more comfortable ride.

Internal testing conducted by Zipp reveals that the 303 S achieves an extraordinary 10 percent reduction in power consumption compared to its top competitor, enabling riders to ride at 40kph on a smooth flat road with a 28mm tire. These remarkable gains in watt savings solidify its status as a groundbreaking wheelset. Furthermore, the 303 S boasts all-new cosmetics, setting riders apart from the pack, and is offered at an attractive price point.

In summary, the Zipp 303 S Tubeless Disc Brake wheelset is the epitome of versatility and speed, combining cutting-edge design, exceptional performance, and a striking aesthetic. It empowers riders to conquer any road surface while delivering an exhilarating experience that exceeds expectations.
