Zipp 303 NSW Carbon Clincher Wheel - Front
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. And since wheels also need to be able to slow you down too, the new Showstopper silicon carbide brake track provides unmatched stopping power and modulation, in either the wet or dry--a first for carbon wheels.
