Zipp 303 NSW Carbon Clincher Tubeless Disc Rear Wheel
The 303 NSW features a rim shape that came out of more than 40 concept studies and endless trips to the ARC wind tunnel, and gives a substantial savings over the 303 Firecrest shape. The 303 NSW not only features improved aerodynamics, but is also one of the lightest performance wheelsets Zipp has ever produced. The new ImPress graphics are also printed directly on to the wheel, so they no longer cover up the dimples on the rim, allowing for a smoother airflow across the wheel. And speaking of those dimples, they've been realigned into an ABLC SawTooth design that diminishes the small air vortices that can build up on the rim, saving you even more time.
The 303 NSW Tubeless Disc-brake is optimized for wide tires to meet the performance needs of modern riders in search of low rolling resistance and high comfort. Additionally, Zipp engineers carefully considered the rim-to-tire interface and how specific tire and rim widths affect aerodynamic performance. Designed to be tubeless compatible, the wheel features a rim bed made with internal ridges to lock the tire's bead in place. A tubeless setup allows you to run lower tire pressure for more comfort while reducing the risk of pinch flats.
