Uncompromising aerodynamics. Exceptional efficiency. World-class racing performance.

The ZIPP 858 NSW D1 Carbon Tubeless Disc Rear Wheel is engineered for cyclists and triathletes seeking maximum aerodynamic efficiency, exceptional speed, and outstanding performance in competitive racing conditions.

Featuring ZIPP's revolutionary Sawtooth rim profile and advanced Total System Efficiency (TSE) technology, this premium carbon rear wheel is designed to reduce aerodynamic drag, rolling resistance, and energy losses while delivering exceptional stability in crosswinds.

The distinctive 82–85 mm undulating rim profile combines the aerodynamic benefits of a deep-section wheel with improved handling characteristics. Its lightweight carbon construction and 23 mm internal rim width provide an ideal platform for modern tubeless road tires.

At the heart of the wheel is the advanced ZIPP ZR1 SL hub with ceramic bearings, engineered for smooth rotation, efficient power transfer, and reliable performance under demanding racing conditions.

The hookless tubeless rim design supports lower tire pressures, improving traction, comfort, and rolling efficiency while maintaining excellent aerodynamic performance.

Available with SRAM XDR or Shimano HG freehub compatibility, the ZIPP 858 NSW D1 is an outstanding upgrade for high-performance road bikes and triathlon machines.
