Zipp 858 NSW Carbon Clincher Disc Brake Front

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 Carbon Clincher Disc Brake 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 minimizing concerns over control, the 858 NSW ushers in a new era where aerodynamically efficient deep-section wheels are no longer reserved only for ideal racing conditions—the 858 NSW is an every-condition race wheelset.

Adding to the 858 NSW Disc brake’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; while it’s disc-specific rim design features our patented NSW-exclusive HexFin ABLC dimples extending all the way to the rim’s edge for maximum aero efficiency and crosswind stability.

Designed for road or triathlon applications, the 858 Carbon Clincher NSW Disc brake’s advanced aero efficiency, crosswind stability, responsive handling, and unrivalled braking are engineered to make what was once impossible… possible.
