What Our Gearhead® Experts Are Saying:"The 454 NSWs changed my entire view on aero wheels. They stay steady in gusty winds, feel unbelievably fast on flat roads, and actually climb lighter than most mid-depth wheels. Total race-day confidence."Every ride feels faster and more stable when we roll on the Zipp 454 NSW Tubeless Disc-Brake wheels. Designed for maximum aerodynamic gains without sacrificing stability, the 454 NSW brings serious racing speed to every road and every condition. The Sawtooth rim profile, complete with Hyperfoil nodes and HexFin dimpling, slices through crosswinds and delivers aero benefits without instability. The hookless carbon construction not only saves weight but enhances durability, while the Total System Efficiency (TSE) concept reduces rolling resistance, vibration losses, and aerodynamic drag. With 23mm internal widths optimized for 28mm tubeless tires, premium ZR1 SL hubs with ceramic bearings, and a lightweight build, the 454 NSW transforms every ride into a pure expression of speed and control.
