Zipp 303 SW offers performance on all roads with SRAM AXS-connected in-wheel tire pressure monitoring. Zipp’s 303 SW Tubeless Disc-brake wheelset offers superior speed on all roads, no matter the surface. Steeped in Zipp’s legacy of innovation, the 303 SW is a modern classic wheelset, fully capable of road, gravel, cobbles, and cyclocross riding.
Tire pressure under control, performance in focus: The Zipp 303 SW for modern riding demands
The Zipp AXS wheel sensor is integrated into the 303 SW rim and precisely monitors the tire pressure on the wheel. This allows you to monitor and analyze tire pressure in real time without the need to attach an external device to the valve stem. Fine-tuning tire pressure helps riders optimize speed and performance in an ever-changing environment. You should check the pressure immediately before riding; a green light means you’re ready to go. check the pressure while riding to find your ideal setting and detect problems early. The 40 mm high rim design of the 303 SW is based on the design of the 303 XPLR for gravel. The wide rim design ensures high aero efficiency and low rolling resistance on a wide tire platform designed for modern riding with lower tire pressure. The rim profile ensures low drag and an improved transition between rim and tire, which increases aerodynamic efficiency on wider tires.
The wide rim profile also ensures less tire deformation and therefore lower rolling resistance. The combination of the wider tire, increased tire volume and lower tire pressure helps to reduce rider fatigue by balancing the handling in difficult road conditions – the tire and wheel system absorbs the shocks, not the rider. A revised carbon layup and design has given the already super-stable 303 SW an almost 10 percent improvement in impact resistance while keeping weight down. The 303 SW is optimized for tires between 30 and 35 mm wide, with the best performance coming from 35 mm tires. The 303 SW rims have a special shape that protects the tire in the event of an impact that would otherwise cause a puncture. The centerpiece is the ZR1 hubset, now equipped with stainless steel bearings for improved durability and smoother running.
