2021 ZIPP 454 NSW THRU ROAD BIKE WHEELSET SRAM XDR 12 SPEED

The ultimate all-around speed weapon from Zipp is now tubeless ready. That means you get all of the aero advantages of the 454 NSW Tubeless Disc-brake wheelset with the added benefit of increased cornering grip and compliance with reduced rolling resistance.

The wheelset has a 19mm internal width, which is optimized for running wider tubeless tires at reduced air pressure. The 454 NSW's undulating 53/58mm-deep rim shape, Zipp's proprietary Sawtoothâ„¢ profile, takes design cues from nature for the highest performing wheel when it comes to aero efficiency and crosswind stability. A humpback whale's fast and graceful movements are aided by tubercles on its pectoral fins.

These structures inspired Zipp advanced development engineers to, for the first time, systematically apply biomimicry to solve the complex challenge of designing a wheel, with the undulating Hyperfoilâ„¢ nodes, that reduces both aerodynamic drag and side force. Combined that with tubeless compatibility and the power of disc brakes, and you are set for the ultimate in Zipp performance.

Features:
New Zipp graphics and cosmetic identity that screams speed, applied using Zipp's ImPress direct-print technology.
19mm internal width and tubeless compatibility for optimization of wider tires with lower tire pressure
Cognition DB hubset rolls efficiently whether you are pedaling or coasting. Its Axial Clutch technology allows the freehub's ratcheting mechanism to deliver half the mechanical drag of conventional three-pawl hubs.
Sawtooth rim with Hyperfoil nodes and HexFin ABLC dimple pattern for top aero and crosswind-stability performance with an undulating 53/58mm rim depth
Center locking rotor interface.
Lockring is NOT included
Ships with 12mm front and rear end caps (Disc-brake)
XDR freehub only
