Zipp 858 NSW Rear Tubeless Rim Brake Carbon Wheel (SRAM/Shimano)

Radical by Design, Evolutionary by Nature
Zipp’s ultimate aero weapon is now tubeless ready. That means you get the many aero advantages of the 858 NSW Tubeless Rim-brake wheelset with the added benefit of increased cornering grip and compliance with reduced rolling resistance. The wheelset’s 18mm internal width is optimized for running wider tyres at reduced air pressure. The 858 NSW’s undulating 77/82mm-deep rim shape, our proprietary Sawtooth profile, takes design cues from nature for our highest performing wheel when it comes to aero efficiency and crosswind stability. These structures inspired Zipp advanced development engineers to, for the first time, systematically apply biomimicry to solve the complex challenge of designing a wheel, with the undulating Hyperfoil nodes, that reduces both aerodynamic drag and side force. When it comes time to scrub off speed or stop, disc brakes will give you the confidence and stopping power you need.
