You could make an argument that the 303 Firecrest is the most successful wheel Zipp has ever made. With wins at Paris-Roubaix, the Tour de France, and other big time races, it's tough to see how Zipp could improve on such a wheel. But the engineers at Zipp have never been ones to rest on their laurels, so they went back to the lab and came out with the Zipp 303 NSW. First things first: What does NSW mean? NSW is the name of Zipp's super-secret speed lab. According to our SRAM rep, there's only a handful of people in the entire company that have access to the facility, and it's where their most exciting developments happen. So what makes the 303 so fast? Glad you asked.

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.
