Zipp 303 Firecrest Carbon Tubeless Disc Brake Shimano Rear Wheel

The Zipp 303 Firecrest Carbon Tubeless Disc Brake Front Wheel is an adaptable performer that is completely capable of excelling across the gamut of riding scenarios thanks to its thoroughly meticulous design and advanced materials. Whether climbing steep Pyrenean mountain passes, powering along in a solo break or dabbling with the gravel the 303 will work with consummate ease.

The finest of carbon material is used within the rim structure to grant a blend of lateral stiffness, strength and low weight. This material is formed into a sophisticated, wide and bulbous cross-sectional profile that is tuned via Zipp's AeroBalance concept which utilises the wind tunnel, CFD computer simulations and real-world rider testing to elicit the lowest amounts of drag and exceptional crosswind stability. The dimpled rim surface pattern complements this by smoothing the airflow around the rim body to improve aerodynamic performance further.

The internal rim structure features a hookless design and Tubeless Made Easy technology to glean the most from tubeless-ready tyres whether on the road or during installation. The broad inner rim width helps by spreading the tyre beads further apart to promote a superior tyre profile and an increased air volume that, in turn, drastically reduces rolling resistance, improves comfort and enhances cornering grip.

The disc brake specific hub is Center Lock compatible and encases super smooth stainless bearings with improved seals for increased weather protection. Sapim CX-Sprint spokes bring everything together via a 2-cross lacing pattern to bestow admirable amounts of stiffness and resilience.
