Zipp Wheels

• The 808 Firecrest Tubeless Disc-wheels are all about science to achieve speed. That’s the perfect approach for Zipp’s stiff deep-rim choice for criteriums, road racing, or any kind of hammer-fest. At 80mm deep, its rim is designed to make you faster in every way. Zipp’s Total System Efficiency design approach, or TSE, infuses the 808 Firecrest with new features, including a huge drop in weight from its previous iteration, well more than 280 grams. Also, the wheel is designed with a hookless and tubeless rim profile and 23mm internal width. That’s ideal for running wider tires at lower pressure for reduced rolling resistance and greater cornering grip.
  • TSE attacks the four primary barriers to speed: Wind Resistance, Gravity, Rolling Resistance, and Vibration Losses
  • Full Carbon Firecrest rim shape provides high aero efficiency and crosswind stability
  • ABLC Technology uses a complex dimpling pattern to improve aero efficiency
  • Optimized for tubeless tires, with the option to run Tubeless or tubeless ready tires with tubes
  • ZR1 Disc Brake hub features a better seal design for improved durability
  • Built with Sapim CX Sprint J-bend spokes

Built for speed on any surface, the Zipp 303 SW is your go-to wheelset for road, gravel, cobbles, and cyclocross. It features Zipp’s integrated AXS Wheel Sensor, letting you monitor tire pressure in real time—no valve-mounted devices needed. Check before you ride (green means go) and stay dialed in as conditions change. Inspired by the 303 XPLR, the 40mm-deep rim uses a wide design for better aerodynamics and lower rolling resistance with wider tires. The result? A smoother, faster ride with less fatigue. The improved carbon layup increases impact strength by nearly 10%, while keeping weight low. Optimized for 30–35mm tires (best with 35mm), the rim shape helps prevent pinch flats and improves tire-rim integration. At the core is the updated ZR1 hubset with stainless steel bearings for smoother, longer-lasting performance.
