Zipp’s 303 S Carbon Clincher Disc Brake Rear Wheel combines lightweight construction with versatile performance for road and mixed-surface cycling.
Its 45mm rim depth and widened internal profile deliver efficient speed, stable handling, and improved ride quality across a variety of tyre widths and pressures. Tubeless-ready design allows lower pressures for increased grip and comfort on pavement or gravel.
Engineered for riders seeking fast, adaptable wheels, the 303 S performs on smooth roads, rolling terrain, and light gravel. The wider rims optimise tyre shape, creating a larger contact patch that enhances cornering confidence, descending stability, and traction in wet conditions. Reduced rolling resistance and vibration damping improve comfort, while its aerodynamic platform offers measurable power savings at race speeds.
