Zipp 858 NSW 23mm Hookless Disc Brake Carbon XDR Rear Wheel

Zipp's ultimate aero weapon is now faster than ever.

Thanks to new Total System Efficiency technology, the 858 NSW Carbon Tubeless Disc wheel features a tubeless and hookless rim profile for seamless tyre interface and a huge drop in weight. This gives the benefit of deep rims at a weight associated iwth rims that are 20mm shallower! The wheek;s internal width is 23mm, ideal for running wider tyres with lower pressures for decreased rolling resistance. The result is a lighter faster wheel designed for triathletes, time trial specialists, and any other speed freak. What's more, while the 858 NSW is optimised for tubeless tyres, there is still the option to run tubeless ready tyres with tubes.
