Zipp 404 Firecrest Carbon Tubeless Clincher Wheelset

The Zipp 404 Firecrest Carbon Tubeless Clincher Wheelset partners the brand's exhaustive aerodynamic know-how with state of the art carbon materials to elicit a versatile performance across any topography. When dancing up sharp inclines, sprinting for the line or putting out a solo effort in any distance of triathlon the 404 Firecrest infuses enthusiasm and vigour into any rider.

The finest carbon materials and resins are blended within the structure of the rims to provide an optimum ratio of lateral stiffness, strength and low weight. This sophisticated carbon composition is formed into a 58mm deep rim profile that has been gleaned from hours of meticulous testing to realise markedly lower drag numbers and increased crosswind stability. The ABLC dimple pattern complements this by encouraging the air particles to flow cleanly and crisply across the rim's surface, thus further reducing drag across the full sweep of yaw angles.

A wide internal rim width coerces the tyre into a superior cross-sectional silhouette and this, in turn, leads to lower rolling resistance, increased comfort and enhanced cornering grip. This internal format combines perfectly with the advanced traits of tubeless-ready tyres but is also compatible with standard clinchers should preference, or riding style dictate their use.

Confidence-inspiring braking performance, even in the wet, is bestowed by the Showstopper brake track and its friction enhancing scalloped surface. Meanwhile, the German-engineered ZR1 hubs add smooth bearings and a sharp reacting, 66 point engagement freehub into the build.

Everything is comprehensively brought together via the use of the esteemed Sapim CX-Ray spokes and evenly tensioned lacing patterns to award optimal amounts of reliability and robustness.


  • QR end caps
  • Quick release skewers


  • A wheelset that combines aerodynamics, low rolling resistance, lateral stiffness, strength and comfort to excel over rolling climbs, across wind-swept plains, when sprinting for the line and in valiant solo efforts
  • The full carbon rims are realised from the finest materials to promote a high stiffness to weight ratio
  • 58mm deep, AeroBalance derived rim profiles are honed via CFD computer simulations, wind tunnel testing and pro rider feedback to simultaneously lower drag and improves crosswind stability
