Zipp MY26 858 NSW Hookless Front Wheel

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 a seamless tire transition and significant weight reduction. The 858 offers the advantages of our high rims at a weight typically associated with rims 20 mm lower. The internal width of the wheel is 23 mm, making it ideal for riding wider tires at lower pressures, thereby reducing rolling resistance. This is how TSE technology helps you overcome the four obstacles to speed: aerodynamic drag, gravity, rolling resistance, and vibration losses. The wavy rim shape of the 858 NSW, with a height of 82 mm to 85 mm, 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 other serious speed enthusiasts. And although this wheelset is optimized for tubeless tires, you still have the option to use tubeless-ready tires with a tube. The 858 NSW is fastest with a 28 mm tire. In triathlons, wider tubeless tires at lower pressures are faster and provide a smoother ride, allowing your body to feel fresher for the running 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 engagement points.
