Zipp 454 NSW (B1)

Bio-Inspired Speed.

The 454 NSW is defined by its revolutionary Sawtooth™ rim profile. Ranging between 53mm and 58mm in depth, this undulating shape creates "Hyperfoil™" nodes that reduce both aerodynamic drag and side-force. This means that when the crosswinds pick up on an exposed coastal road or between city buildings, the 454 NSW remains steady, allowing you to stay in your aero tuck longer and ride with more confidence than on any other deep-section wheel.

Why the 454 NSW is the Professional Benchmark:

• Sawtooth™ & Hyperfoils™: The varying rim depth creates vortex shedding that stabilizes the wheel in crosswinds. You get the speed of a 60mm wheel with the handling and stability of a 30mm wheel.

• Cognition™ V2 Hubset: Featuring the Axial Clutch V2™ technology, these hubs decouple the ratcheting mechanism when coasting. This drastically reduces internal mechanical drag, allowing you to maintain higher speeds while freewheeling.

• HexFin™ ABLC Dimples: Specialized hexagonal dimples are molded into the rim to optimize the boundary layer of air. This keeps the airflow "attached" to the rim longer, further reducing drag and improving stability at high yaw angles.

• Impress™ Graphics: Zipp’s Impress graphics technology prints the logos directly onto the carbon rim. This doesn't just look stunning; it allows the dimples to do their job without being covered by heavy decals, and it significantly reduces weight.

• Tubeless Efficiency: The 454 NSW is optimized for tubeless tires, allowing you to run lower pressures for increased grip, improved comfort, and a lower rolling resistance compared to traditional tube-type setups.

• TSE™ Technology: Total System Efficiency. Zipp focuses on the four barriers to speed: Wind Resistance, Gravity, Rolling Resistance, and Vibration Loss. The 454 NSW is designed to conquer all four simultaneously.

The Alegro Perspective: There is no other wheel on the market that looks like, or performs like, the 454 NSW. In our experience, it is the only "deep" wheel that doesn't feel like a sail in the wind. The B1 generation, with the updated Cognition V2 hubs, is incredibly fast and hauntingly quiet. If you want the absolute best that carbon technology has to offer, and you want your bike to look like it belongs in the future; this is the wheelset.
