ZippÕs 353 NSW Tubeless Disc-brake wheelset is the pinnacle of our pursuit of versatility and speed. This wheelset fuses ZippÕs two most advanced approaches, Sawtoothª rim profile and TSEª, for an all-encompassing approach to performance. With its undulating 45-mm deep rim shape, the 353 NSW provides speed on every terrain with best-in-class aerodynamic efficiency and crosswind stability. The 353 NSW is ZippÕs lightest tubeless wheelset yet, making it a fast-puncher ready to fight its way into the breakaway. ZippÕs use of hookless (straight side) rims in the 353 NSW is integral to achieving our mission of Making You Faster. With hookless, the transition between the tire and the rim is more seamless and aero. ZippÕs hookless rims have more efficient resin distribution, which means lighter wheels. They also are highly durable. ZippÕs 353 NSWÕs Sawtoothª rim shape with Hyperfoilsª optimizes aerodynamic efficiency and crosswind stability. The Sawtoothª design also allows the rim to be structurally strong but light. That will help you snap out of corners and maintain that speed no matter the terrain, especially the steep, punchy stuff. The 353 NSW utilizes ZippÕs Total System Efficiencyª, or TSEª, approach to wheel design: overcoming specific barriers to speed: wind resistance, gravity, rolling resistance, and vibration losses. The wheelsetÕs 25mm internal width is ideal for running wider tubeless tires at reduced air pressure for a more efficient ride. At the center of the 353 NSW is the Cognition V2 Hubset re-engineered with an updated Axial Clutch V2ª mechanism for quicker engagement and lower friction as well as improved durability.
