Zipp 858 NSW Carbon Tubeless Disc Brake Rear Wheel

Featuring the most refined of aerodynamic traits and advanced materials, the Zipp 858 NSW Carbon Tubeless Disc Brake Rear Wheel elicits an industry-leading performance when competing solo against the clock in time trials or triathlon events.

A sophisticated carbon lay up bestows high lateral stiffness, robustness and low weight into the rim structure. This state of the art composite material is moulded into an undulating, Sawtooth rim profile that features a series of Hyperfoil nodes throughout its inner circumference. This innovatory and radical-looking silhouette promises the lowest possible drag with optimum amounts of stability across a huge scope of yaw angles. The HexFin ABLC surface dimples and ridges complement this by reducing air turbulence across the rim's surface to further enhance aero prowess even during crosswinds.

A wider internal rim format is compatible with tubeless-ready or standard clincher tyres and forces these to take an improved cross-sectional profile by spreading their beads further apart. This refined tyre outline results in lowered rolling resistance, decreased drag numbers, improved comfort and maximised cornering grip.

The Cognition disc brake specific hub encases super smooth, sealed bearings for long-lasting performance. The Axial Clutch freehub disengages when coasting to save energy before the Centre Lock disc brake rotor attachment is reassuringly stable. Sapim CX-Ray spokes comprehensively complete the build via an evenly tensioned 2-cross lacing pattern.
