The design fuses two of Zipp’s most advanced approaches; the Sawtooth rim profile and TSE, for an all-encompassing approach to performance. At the center of the 454 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. Tubeless and hookless rim profile, optimized tire bed for easy tire installation. 58-mm deep rim shape provides speed on every terrain with best-in-class aerodynamic efficiency and crosswind stability. 23mm internal width maximizes performance when used with 28mm tires. Total System Efficiency (TSE) for greater efficiency and reduced rolling resistance. Sawtooth rim with Hyperfoil nodes and HexFin ABLC dimple pattern for top aero and crosswind-stability performance with an undulating rim depth. Cognition V2 hubset rolls efficiently, with Axial ClutchV2 technology to reduce drag and lowers friction. Ships with 12mm front and rear end caps. Center locking rotor interface, lockring included.
