Zipp 454 NSW Rear Wheel – 700, 12 x 142mm, Center-Lock, XDR, Tubeless, Carbon, B1

454 NSW Tubeless Disc-brake wheels are the ultimate choice for road racing, delivering everything the performance cyclist demands. 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 installation58-mm deep rim shape provides speed on every terrain with best-in-class aerodynamic efficiency and crosswind stability23mm internal width maximizes performance when used with 28mm tiresTotal System Efficiency (TSE) for greater efficiency and reduced rolling resistanceSawtooth rim with Hyperfoil nodes and HexFin ABLC dimple pattern for top aero and crosswind-stability performance with an undulating rim depthCognition V2 hubset rolls efficiently, with Axial ClutchV2 technology to reduce drag and lowers frictionShips with 12mm front and rear end capsCenter locking rotor interface, lockring includedItem SpecificationsRear Axle12mm Thru x 142mmRim Width (Internal)23Cassette Body TypeSRAM XDRValvePrestaColorCarbonWheel Size700cDefined ColorCarbonISO Diameter622 / Road / 29″Tire TypeTubeless ReadyRim MaterialCarbonHub/Brake CompatibilityCenter-Lock Disc
