Zipp 303 SW Carbon Wheelset

Versatile carbon performance for road, gravel, and beyond

The Zipp 303 SW wheelset is designed as a true do-it-all performance wheel, built to handle everything from fast road riding to rougher surfaces like cobbles and light gravel. Combining modern wide rim design with Zipp’s efficiency-focused engineering, it delivers speed, comfort, and durability in equal measure.

At the heart of the 303 SW is its wide, shallow rim profile, optimised for real-world riding rather than wind tunnel numbers alone. The 40mm depth improves stability in crosswinds, while the increased internal width supports wider tyres at lower pressures—enhancing grip, comfort, and rolling efficiency across mixed terrain.

The hookless tubeless carbon rim creates a seamless tyre interface, reducing rolling resistance and improving impact strength. Paired with Zipp’s Total System Efficiency (TSE™) philosophy, the 303 SW is built to minimise energy loss from vibration and road buzz—keeping you fresher for longer rides and rougher routes.

A standout feature is the integrated AXS tyre pressure monitoring system, allowing you to track pressure in real time for optimal performance and safety.

The wheelset is built around Zipp’s ZR1 hubset with stainless steel bearings, delivering smooth rolling and dependable engagement for both racing and all-day riding.
