The 45mm deep rim is constructed from stiff unidirectional carbon and is designed for a tubeless setup, one that'll bring you the benefits of running lower tyre pressures, namely faster smoother rolling, more comfort and a reduced risk of punctures. 24 Sapim CX Sprint spokes and a 176D hub complete the build, and it's available in both Shimano/SRAM and SRAM XDR configurations.



  • Zipp graphics and cosmetic identity that scream speed
  • Fastest with 28mm, also fits wide gravel tyres up to 50mm wide
  • Wide rim optimises tyre profile to allow lower tyre pressure, especially with tubeless. The result is a larger contact patch for increased grip for confident cornering, descending, and handling in wet conditions
  • Lower tyre pressures and larger volume provides a compliant ride with fewer vibrations
  • Significant watt savings when running larger tyres at lower pressure
  • Wide hookless rims create a seamless transition to the tyre, reducing drag
  • 176 DB hub with Centre-Lock interface
  • Only compatible with tubeless specific tyre.
