With the introduction of the radical biomimicry-derived 454 NSW Carbon Clincher, Zipp proved that aero efficiency and crosswind stability are not mutually exclusive aero wheel design goals. Using a similar Sawtooth rim design, the 858 NSW wheelset goes 24 millimeters deeper than the 454 and delivers even greater gains in aero efficiency while providing a level of rider control in crosswinds that was previously unthinkable with conventional deep-section wheel designs.

By eliminating concerns over control, the 858 NSW ushers in a new era where aerodynamically efficient deep-section wheels are no longer a race-day-only option—they’re everyday wheels. Adding to the 858’s versatility, its lightweight and laterally stiff rim imparts a level of responsiveness previously only attributed to much shallower wheels, keeping bike handling lively and quick. The 858 delivers the best braking available thanks to Zipp's NSW-exclusive Showstopper brake track found on the rim brake version of the 858 NSW. Designed for road or triathlon applications, the 858 NSW’s advanced aero efficiency, crosswind stability, responsive handling, and unrivaled braking are engineered to make what was once impossible…possible.
