Zipp s 353 NSW Tubeless Disc-brake wheelset is the pinnacle of our pursuit of versatility and speed. This wheelset fuses Zipp s two most advanced approaches, Sawtooth rim profile and Total System Efficiency for an all-encompassing approach to performance. Zipp's lightest tubeless ready wheelset yet at just 1255g per pairSawtooth rim with Hyperfoil nodes and HexFin ABLC dimple pattern for top aero and crosswind-stability performance with an undulating rim depth25mm internal width and tubeless compatibility for optimization of wider tyres with lower tyre pressureCognition DB hub set with Axial Clutch freehub rolls efficientlySuitable for 100x12mm (front) and 142x12mm (rear) axles - sold individually as front or rear wheelsWith 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 Zipp s lightest tubeless wheelset yet, making it a fast-puncher ready to fight its way into the breakaway. With Zipp s hookless rims, the transition between the tire and the rim is more seamless and aero. Zipp s hookless rims have more efficient resin distribution, which means lighter wheels. They also are highly durable. Zipp s 353 NSW s Sawtooth rim shape with Hyperfoils optimizes aerodynamic efficiency and crosswind stability. The Sawtooth 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 Zipp s Total System Efficiency, or TSE, approach to wheel design: overcoming specific barriers to speed: wind resistance, gravity, rolling resistance, and vibration losses. The wheelset s 25mm internal width is ideal for running wider tubeless tires at reduced air pressure for a more efficient ride. At the centre of the 353 NSW is the Cognition V2 Hubset re-engineered with an updated Axial Clutch V2 mechanism for quicker engagement and lower friction as well as improved durability.
