Zipp considers their 454 NSW wheelset to be ultimate road racing wheelset. This speed and versatility oriented set balances speed, weight, and aerodynamics for the rider who wants to thrive in all areas. It is aerodynamically efficient and stable in all wind conditions, accounting for all possible wind angles. An undulating 58mm Sawtooth rim shape with Hyperfoils makes it the most aerodynamic and stable wheel on the market. It also includes Zipp Total System Efficiency which combats any enemies of speed. This includes wind resistance, rolling resistance, gravity, and body vibration losses. Mitigating all of these limiting factors leads to higher speeds with less effort and the fastest ride on the road.

INCLUDES

12mm hub end caps

Center Lock lock rings

HIGHLIGHTS

The range-topping 454 NSW is the racer's favourite as it is fast in a vast range of road riding scenarios

Conceived via Zipp’s “Total System Efficiency” (TSE) design concept that equally factors aerodynamics, weight, rolling resistance and vibration losses (comfort)

A special tool that measures aerodynamic drag, rolling resistance, wind speed and wind yaw angle while on the road, was key in the development of these wheels 

The TSE holistic design approach equals more speed in real-world riding conditions rather than just wind tunnels

The rims use the highest grade of carbon fibre to lower weight, increase strength and improve lateral stiffness

The hookless internal rim design is for tubeless-ready tyres only, promotes a more aerodynamic tyre to rim interface and lowers weight via more even resin distribution

A 23mm internal rim width works optimally with wider tubeless-ready tyres, lowering rolling resistance and improving comfort

Undulating 53/58mm deep, SawTooth rim shape with Hyperfoil nodes optimises aerodynamic efficiency and crosswind stability

The SawTooth rim profile increases lateral stiffness for faster climbing and snappier acceleration

HexFin ABLC rim surface dimple pattern further lowers drag

Cognition V2 hubset with an Axial Clutch V2 freehub for decreased resistance when freewheeling and almost instant pedalling engagement
