Zipp 858 NSW Carbon Road Wheelset

Unleash the ultimate aerodynamic weapon with the Zipp 858 NSW Tubeless Disc Brake Wheelset. Engineered for pure, unadulterated speed, the 858 NSW is Zipp’s premier deep-rim choice for triathlons, time trials, and flat-out road racing. Featuring a radical undulating 82mm-85mm rim depth, it utilizes biomimicry to deliver the aero benefits of a deep section wheel while maintaining the handling and crosswind stability of a much shallower rim. This wheelset doesn't just cut through the wind; it tames it, allowing you to stay in your aero tuck longer and crush your personal bests with absolute confidence.

Key Features:

Biomimetic Sawtooth Rim Profile: The undulating rim depth aggressively optimizes aerodynamic drag while the Hyperfoil nodes provide unmatched stability in unpredictable crosswinds.

Cognition V2 Hubset: Built with Axial Clutch V2 technology, this hubset disengages the ratchet mechanism when coasting to eliminate mechanical drag and preserve every watt of momentum.

Total System Efficiency (TSE): A high-performance hookless rim design that reduces weight and creates a seamless tire-to-rim transition for lower rolling resistance and increased speed.

HexFin ABLC Dimple Pattern: A complex, hexagonal dimple surface that manages airflow across the rim to minimize drag and keep you aerodynamically slippery at all yaw angles.
