Aerodynamically Superior. For the Winning Athlete — 858 NSW Tubeless
For the rider who demands the look and feel of pure speed, we welcome the Zipp 2021 858 NSW Tubeless Rim Brake Wheelset's new aesthetics featuring Zipp's first-class ImPress direct-print technology.
Now the wheelset with the ultimate aerodynamic advantage is now tubeless-ready. With a range of aero advantages of the 2021 858 NSW, you also receive increased cornering grip and compliance with reduced rolling resistance.
The 19mm internal width of the wheelset allows for wider tires running at reduced air pressure. The 858 NSW's undulating 77/82mm-deep rim shape, proprietary Sawtooth™ profile, takes design cues from nature for the highest performing wheel when it comes to aero efficiency and crosswind stability.
These structures inspired Zipp advanced development engineers to, for the first time, systematically apply biomimicry to solve the complex challenge of designing a wheel, with the undulating Hyperfoil™ nodes, that reduce both aerodynamic drag and side force.
The 858 NSW Tubeless is not designed for every triathlete, time trialist, or aggressive road rider.
Only the athlete ready to break PRs.
