If you need confirmation that technology is changing road bikes for the better, the 404 NSW Carbon Clincher Tubeless Disc-brake wheelset leaves no doubt. Zipp’s 404 wheels – with their 58mm rim depth – are synonymous with all-around high performance. NSW technology adds to this legacy enhanced aero performance and tubeless compatibility, all with the benefits of disc brakes.
The NSW Tubeless Disc-brake wheels are aerodynamically optimized for wide tires to meet the performance needs of modern riders in search of low rolling resistance and high comfort. Throughout the development process our engineers carefully considered the rim-to-tire interface and how specific tire and rim widths affect aerodynamic performance.
Rim depth and shape along with tire selection were all carefully considered throughout the development process. The 404 NSW, with an internal width of 19mm, is optimized for smoother pavement and are aerodynamically optimized for 25mm tires. By extending our patented ABLC™ Sawtooth™ dimples all the way to the rim’s edge on each of the wheels, NSW disc brake rims deliver higher frequency wind vortex shedding for best-in-class crosswind stability.
Tubeless compatible, the 404 NSW Tubeless Disc brake features a rim bed made with internal ridges to lock the tire’s bead in place. A tubeless setup allows riders to select lower tire pressure for more comfort while reducing the risk of pinch flats. Tires such as the Zipp Tangente RT28 or RT25 Road Tubeless are a perfect match for the new wheels and deliver exceptionally low rolling resistance and high cornering grip.
All NSW rims are handmade in Indianapolis, where Zipp's engineering, manufacturing, and testing are conducted and includes "The Nest" advanced development lab where NSW was born.
