Zipp 808 NSW Carbon Clincher Wheel - Rear
The 808 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 808 Firecrest rim shape. 3-4 watts might not sound like much, but over a 112 mile Ironman distance, that adds up to over 90 seconds, and means you'll have more energy left over for your run. 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.
