The 303 SW represents Zipp's contemporary approach to versatile road and multi-surface performance, engineered for modern riders demanding capability across tarmac, gravel, cobbles, and cyclocross terrain.
The defining innovation is the integrated Zipp AXS Wheel Sensor embedded within the rim, enabling real-time tyre-pressure monitoring without external valve-stem devices, allowing pre-ride verification and dynamic pressure optimisation during riding.
The 40mm carbon hookless rim features a generous 25mm internal width, drawing design principles from the gravel-focused 303 XPLR to enhance aerodynamic efficiency and reduce rolling resistance whilst supporting wider tyres at lower pressures for improved compliance.
Enhanced carbon layup delivers approximately 10% greater impact resistance whilst maintaining lightweight construction, with optimised geometry for 30–35mm tyres and pinch-flat protection. The updated ZR1 hubset incorporates stainless steel cartridge bearings for extended durability and refined engagement.
