2021 Zipp 454 NSW Tubeless Rim Brake Wheelset — The Pinnacle of Performance
Zipp NSW is the definition of innovation when it comes to forward-thinking, impressively advanced wheelsets.
The 2021 454 NSW Rim Brake Wheelset, Zipp's ultimate all-around speed weapon, is now tubeless ready. That means you get all of the aero advantages of the 454 NSW Tubeless rim-brake wheelset with the added benefit of increased cornering grip and compliance with reduced rolling resistance.
The wheelset's 19mm internal width is optimized for running wider tires at reduced air pressure. The 454 NSW's undulating 53/58mm-deep rim shape, the proprietary Sawtooth™ profile, takes design cues from nature for Zipp's 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 Hyperfoil™ nodes, that reduce both aerodynamic drag and side force.
Combined that with tubeless compatibility, and you are set for the ultimate in Zipp performance.
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
