Zipp Rear wheel 858 NSW Disc Centerlock, 12 x 142 mm - SRAM XDR

The ultimate aero wheelset from Zipp is faster than ever before 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 a seamless tire transition and significant weight reduction. The 858 offers you the advantages of our high-profile rims at a weight typically achieved by rims 20 mm lower. The wheelset's internal width is 23 mm, ideal for riding wider tires at lower pressures to reduce rolling resistance. Thus, TSE technology helps you overcome the four barriers to speed: aerodynamic drag, gravity, rolling resistance, and vibration losses.

The wave-shaped rim of the 858 NSW, ranging from 82 mm to 85 mm in height, our patented Sawtooth profile, is our most powerful design for aero efficiency and crosswind stability. The result is pure speed, especially for triathletes, time trial specialists, and all serious speed enthusiasts. Although this wheelset is optimized for tubeless tires, you still have the option to ride 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 provide a smoother ride, keeping your body fresher for the run segment. Disc brakes also offer more reliable speed control and braking power in all weather conditions. The 858 NSW is equipped with the ZR1 SL Premium hubset with ceramic bearings and 66 points of engagement.
