ZIPP 303 S Tubeless Carbon Rear Wheel with Shimano Driver

The ZIPP 303 S Tubeless Carbon Rear Wheel has been designed to offer the same speed and efficiency you've come to love from ZIPP Wheels with the versatility of all-road capability. Sharing its design with ZIPP's Firecrest models, the 303 S has been designed and constructed to conquer the Spring Classics and rides over imperfect surfaces and through all conditions while retaining its efficiency and speed. The result is a wider rim profile than its' predecessor which ensures it's more capable over varied terrain, while also reducing the drag profile for lower rolling resistance.

As is the trend with modern road bike design, the ZIPP 303 S wheels have been designed for use with wider tyres - ZIPP mandates a minimum 25mm wide tyre and it has been aerodynamically optimised for 28mm tyres. However, with the growing demand from riders for versatile, multi-function wheels, you'll find the ZIPP 303 S can accommodate up to 50mm wide tyres for gravel and bike packing adventures! Of course, the reason for the wider profile of the ZIPP 303 S is the fact that it increases rider comfort significantly all while reducing the rider's rolling resistance. This is achieved through wider, higher volume tyres which allow you to ride on lower pressure, saving precious watts and absorbing road feedback.   

With the ZIPP 303 S wheels, you can expect a more comfortable ride than you've ever experienced. Of course, it wouldn't be a ZIPP wheel without a highly efficient and durable hubset! The 303 S features ZIPP's ever-reliable 76/176DB hubset that balances durability and efficiency alongside a highly responsive ride thanks to its 3 PAWL engagement system.

If you're looking to save watts, increase comfort and explore further and faster than ever before, then you'd find it difficult to find a more versatile wheel than the ZIPP 303 S Tubeless Carbon Rear Wheel. It has all the features you could ever want in a tyre that balances the fine line of efficiency, weight and off-road ability!
