Zipp 858 NSW Carbon Clincher Rear

Write a Review
Zipp 858 NSW Carbon Clincher Rear SRAM/Shimano sport factory

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 rim 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’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 NSW also delivers the best braking available thanks to our NSW-exclusive Showstopper® brake track.

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

Faster than an 808. Rides Like a 404.
