Zipp 858 NSW Tubeless Disc Wheels

Zipp’s ultimate aero weapon is faster than ever, thanks to their proprietary Total System Efficiency technology. With TSE, the 858 NSW Carbon Tubeless Disc-brake wheelset features a tubeless and hookless rim profile for seamless tire interface and huge drop in weight. The 858 NSW gives you the benefits of Zipp's rims at weight typically associated with rims that are 20mm shallower. The wheel’s internal width is 23mm, ideal for running wider tires with lower pressures for decreased rolling resistance. That’s how TSE technology helps you conquer the four barriers to speed: Wind Resistance, Gravity, Rolling Resistance, and Vibration Losses. The 858 NSW’s undulating 82mm-85mm deep rim shape, our patented Sawtooth profile, is their highest performing design for aero efficiency and crosswind stability. The 858 NSW features Zipp’s Carbon Internal Reinforcement (CiR), which creates a rim that is 10% lighter and just as strong as previous wheels. The result is pure speed, especially for triath
