Following the success of the 808 NSW, which was ridden to victory at the Pro Men’s Ironman® World Championships and the Elite Women’s UCI Team Time Trial World Championships, Zipp is proud to launch our second wheelset in the NSW Series, the Zipp 404 NSW Carbon Clincher. Our advanced development engineers in our top-secret lab, known as The Nest, have delivered a wheelset with improved braking performance, exceptional aerodynamic efficiency, and unparalleled crosswind stability for our most popular and best-selling rim depth. Like the 808 NSW, the 404 NSW also makes use of our Cognition hubset for increased durability and exceptionally low freehub drag.

No matter where you ride, the 404 NSW is engineered to make that ride faster. With a rim depth of 58mm, the 404 NSW is designed as a do-everything wheelset that is adept at climbing and maintaining speed on the flats; a wheel strong enough to handle the Spring Classics, but light enough to inspire sprints out of corners.
With its advanced aerodynamics, developed using 42 different CFD (Computational Fluid Dynamics) concept studies and months in the wind tunnel; the 404 NSW’s unrivaled crosswind stability saves watts that would have been spent keeping the bike straight, and provides unequivocal confidence for high speed descending.
When it comes time to slow for a corner, our NSW exclusive Showstopper™ brake track stands ready to deliver the best modulation and shortest stopping distances available, regardless of weather conditions or the length of the descent.
