Zipp 303 SW Carbon Front Wheel The Zipp 303 SW Carbon Front Wheel delivers all-road performance with SRAM AXS in-wheel tyre pressure monitoring. Designed for road, gravel, cobbles and cyclocross, this modern classic continues Zipp’s legacy of innovation. At its core, the 303 SW features an internal Zipp AXS Wheel Sensor that enables real-time tyre pressure analysis without the need for an external device. Riders can check pressure before setting off; a green light means ready to ride. Pressure can also be monitored during the ride to optimise performance and detect issues early. The 40mm deep rim takes inspiration from the gravel-focused 303 XPLR, using a wide internal profile that enhances aerodynamic efficiency and lowers rolling resistance with wider tyres. The refined rim shape provides a smoother transition between rim and tyre, improving airflow and increasing speed. This wider stance reduces tyre deflection and contributes to a more comfortable ride by absorbing vibrations over rough terrain. A revised carbon layup increases impact strength by nearly 10 percent without adding weight. Designed for tyres between 30 and 35mm wide, the rim shape helps protect against pinch flats. At the centre is the upgraded ZR1 hub with stainless steel bearings for improved durability and smoother rolling performance.
