Zipp 858 NSW - 00.1918.772.000

Zipp 858 NSW ZR1 SL 82/85mm 12/100mm Disc Tubeless Ready 2025 Carbon Cycling Front Wheel

Introducing the Zipp 858 NSW 00.1918.772.000 wheel, Zipp 's most aerodynamic front wheel ever. Designed for pure performance, this tubeless carbon disc brake wheel strikes the perfect balance between lightness, stiffness, and aerodynamics. It's designed for triathletes, time trialists, and anyone looking for maximum speed.

With exclusive Total System Efficiency (TSE) technology, the Zipp 858 NSW optimizes every detail of the wheel-tire system to reduce the four major speed constraints: wind resistance, gravity, rolling resistance, and vibration losses. The result: exceptional efficiency, even on demanding courses.

Its carbon rim features a unique 82-85mm deep wave profile, Zipp 's famous patented Sawtooth design, ensuring remarkable stability in crosswinds while maximizing air penetration. Light as a 60mm wheel, but as fast as an 85mm, the 858 NSW offers a decisive advantage over the competition.

Technology and design

Total System Efficiency (TSE)

This Zipp technology aims to improve overall speed by simultaneously reducing wind resistance, gravity, rolling resistance, and vibration losses. The tire/rim interface is optimized thanks to the tubeless and hookless design, allowing the use of lower pressures for increased comfort and better efficiency.

Sawtooth Profile

The "sawtooth" rim profile (82 to 85 mm) provides superior aerodynamics and exceptional stability in the face of side wind gusts. This unique wave shape allows for smoother airflow around the wheel, reducing turbulence and improving control at high speeds.

Tire and brake compatibility

Optimized for 28mm tubeless tires, the 858 NSW can also accommodate tubeless-ready tires with inner tubes. CenterLock disc braking ensures precise modulation and consistent power in all weather conditions.

ZR1 SL hub

The premium Zipp ZR1 SL hub, equipped with ceramic bearings and 66 points of engagement, guarantees instant power transmission and optimal durability.
