What Our Gearhead® Experts Are Saying:"I’ve ridden a lot of aero wheels, but the 858 NSW is on another level. It holds speed with less effort, feels stable even in gusty crosswinds, and the braking is incredibly responsive thanks to the disc setup. The Sawtooth rim profile looks wild, but it works—it cuts through the air and manages side forces better than anything else I’ve ridden. It’s a race-day weapon that still handles great on everyday training rides."Speed meets stability in the Zipp 858 NSW Carbon Disc Brake Wheel. Designed for riders chasing every marginal gain, this aerodynamic wheelset features Zipp’s unmistakable Sawtooth rim profile with Hyperfoil nodes, engineered to slice through wind and maintain control in gusty conditions. With an 85mm rim depth and wide 23mm internal width, this wheel encourages lower tire pressures for smoother rolling resistance and improved grip. Optimized for tubeless setups, the hookless carbon rims offer weight savings and enhanced ride feel, while the Cognition DB hub system delivers fast engagement and rolling efficiency. Whether you're sprinting for the line or locking into a long solo effort, the 858 NSW gives you the confidence and aerodynamic advantage to stay out front.
