Zipp 858 NSW Tubeless Disc Brake Rear Wheel

Zipp 858 NSW - for maximum speed and aerodynamic efficiency

Zipp 858 NSW Tubeless Disc Brake – a premium aerodynamic front wheel designed for road cycling, triathlon and time trial. The deep, undulating rim profile is designed to deliver high aerodynamic efficiency and stability in crosswinds.

The 858 NSW uses Zipp’s Total System Efficiency (TSE) concept, designed to improve overall riding efficiency by reducing four key factors that limit speed: aerodynamic drag, weight, rolling resistance and energy loss caused by vibrations.

The Sawtooth rim profile features a variable depth of 82–85 mm. It incorporates Hyperfoil elements and HexFin ABLC dimples designed to improve aerodynamics and wheel stability in crosswinds.

The 23 mm internal-width carbon rim uses a Tubeless Straight Side (TSS) / hookless construction. Zipp states that this model is optimized for 30 mm tires, with a minimum recommended tire width of 28 mm.

The wheel is equipped with the premium ZR1 SL hub and ceramic bearings. The brake rotor uses the Center Lock mounting standard.
