Zipp 454 NSW 700c Wheel Race-ready aero meets real-world versatility The bew Zipp 454 NSW Wheelset is engineered for speed, stability, and energy efficiency in real-world racing conditions. With a 58mm deep undulating Sawtooth(TM) rim and Hyperfoil(TM) nodes, it's Zipp's most aerodynamic and stable profile yet. The 454 NSW features Total System Efficiency (TSE) to combat rolling resistance, wind drag, vibration loss, and gravity, resulting in a smoother, faster ride. The hookless rim interface and 23mm internal width optimize tubeless tire performance when run at lower pressures, while smoothing the transition between tire and rim for increased aero efficiency. At the heart of the Zipp 454 NSW is the ZR1 SL hubset, with ceramic bearings and 66 points of engagement delivering smooth, fast engagement that's ready to respond on race day.
