What Our Gearhead® Experts Are Saying:"The 303 SW wheels deliver a ride that's crazy fast on the road and surprisingly smooth when the pavement ends. I love not having to second-guess tire pressure thanks to the AXS Sensor, and the wide rims make every ride feel more comfortable and controlled."We ride fast and smooth no matter the surface with the Zipp 303 SW Tubeless Disc-brake wheels. Born from Zipp’s obsession with innovation, the 303 SW combines lightweight carbon construction, integrated tire pressure monitoring, and wide-profile aero design to create the ultimate modern wheel for road, gravel, and cyclocross rides. The AXS Wheel Sensor makes dialing in tire pressure a breeze, offering real-time feedback and eliminating the need for external devices. A 40mm rim depth paired with a 25mm internal width optimizes performance for today’s wider tubeless tires, delivering aerodynamic speed with added compliance for rough roads and loose gravel. Whether we’re chasing PRs or tackling backroads, the 303 SW wheels bring unmatched confidence, durability, and versatility to every ride.
