While every wheel manufacture claims to have the "fastest, lightest, most aero optimized wheel" through advance wind-tunnel testing and so on; Real world riding is by nature, unforgiving. Zipp designed the 303 Firecrest wheelset for the real world with vibration dampening properties that smooth out rough roads, a 40mm rim depth that is both aero and light weight, and a hookless bead profile that reduces pinch-flats and simplifies the tubeless set-up process. When the end goal is to become faster on the road, Zipp has your back.


  • ABLC sawtooth dimple design manages airflow around the wheel creating a faster, more stable wheel
  • 40mm rim depth creates an optimal balance between aero-efficiency and light weight 
  • Wide 25mm internal rim width creates a more efficient tire interface 
  • Hookless rim profile designed to streamline the tubeless set-up process and provide pinch-flat resistance
  • AeroBalance optimizes the relationship between aerodynamic drag and crosswind efficiency
  • Total System Efficiency (TSE) results in greater all-around efficiency- wind resistance, rolling resistance, gravity, and vibration loss
  • ZR1 disc brake hubs with 66 points of engagement for a quicker response
