Zipp 858 NSW
Zipp’s ultimate aero weapon is faster than ever, thanks to our 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 gives you the benefits of our deep 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 our 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 the pure speed, especially for triathletes, time trial specialist, and any other speed freak. What’s more, while this wheelset is optimized for tubeless tires, you still have the option to run tubeless ready tires with tubes. The 858 NSW is fastest with a 28mm tire. In triathlon, running wider tubeless tires at lower pressure makes you faster while also smoothing out the ride so your body is fresher for the run. Disc brakes also off er more reliable speed modulation and braking power in all weather conditions. At the center of the 858 NSW is the Cognition V2 Hubset engineered with the Axial Clutch V2 mechanism for quicker engagement and lower friction as well as improved durability.
