Zipp 303 S Carbon Tubeless Disc Brake Center Locking 700

SPEED FOR ALL ROADS AHEAD

The 303 S Series Tubeless Disc Brake wheelset provides today’s cyclists the versatility they demand with the speed they crave. Expanding greatly on its heritage of conquering the Spring Classics, this carbon wheelset maintains an ideal-for-every-terrain 45mm rim depth while adding a significantly wider internal width to provide greater performance and ride quality in almost every measurable way. As road bikes become more versatile than ever, this wheelset offers an entirely new rim profile to optimize performance on any road surface.

Optimized for top aero performance with a 28mm tire but capable of handling gravel tires up to 50mm wide, these wheels are designed to gain speed through increased efficiency. This is achieved by creating a system that reduces wind resistance, rolling resistance, rider fatigue, and weight. The 23mm internal tire bed is designed to be fastest with 28mm tires, allowing for lower pressures that reduce rolling resistance and provide a more compliant ride. According to internal testing, this results in a 10 percent watt savings versus a top peer wheel in total power required to ride 40kph on a smooth flat road.

FEATURES

• New graphics and cosmetic identity that signify speed
• Fastest with 28mm tires, with compatibility for wide gravel tires
• 76 / 176 DB hubs with Center locking interface
• Multiple driver body options for maximum compatibility
• Wide rims optimize tire profile to allow lower tire pressure, especially with tubeless setups
• Larger contact patch increases grip for confident cornering, descending, and handling in wet conditions
• Lower tire pressures and larger volume provide a compliant ride with fewer vibrations
• Significant watt savings when running larger tires at lower pressure
• Wide hookless rims create a seamless transition to the tire, reducing aerodynamic drag
