Zipp Rear Wheel 858 NSW Disc Centerlock, 12 x 142 mm - Shimano/Sram

The ultimate aero wheelset from Zipp is faster than ever thanks to our Total System Efficiency technology. The 858 NSW Carbon Tubeless Disc Brake Wheelset with TSE features a tubeless and hookless rim profile for seamless tire integration and significant weight reduction. The 858 offers you the benefits of our deep rims at a weight typically achieved by rims that are 20 mm shallower. The internal rim width is 23 mm, ideal for running wider tires at lower pressure to reduce rolling resistance. This is how TSE technology helps you overcome the four barriers to speed: aerodynamic drag, gravity, rolling resistance, and vibration losses.

The undulating rim shape of the 858 NSW, ranging from 82 mm to 85 mm in depth, our patented Sawtooth profile, is our highest-performing design for aero efficiency and crosswind stability. The result is pure speed, especially for triathletes, time trial specialists, and all serious speed enthusiasts. And even though this wheelset is optimized for tubeless tires, you still have the option to use tubeless-ready tires with tubes. The 858 NSW is fastest with a 28 mm tire. In triathlon, wider tubeless tires at lower pressures are faster and offer a smoother ride, leaving your body fresher for the run. Disc brakes also provide more reliable speed modulation and braking power in all weather conditions. The 858 NSW is equipped with the ZR1 SL Premium hub set featuring ceramic bearings and 66 points of engagement.
