SawTooth? is the name given to Zipp NSW?s patented variable depth 53/58mm rims. Developed utilizing the principles of the emerging science of biomimicry, Zipp engineers began the rigorous aero development process of SawTooth? utilizing the wind tunnel, CFD, and real-world testing. The result is a rim shape that takes nature?s most elegant design solutions and combines engineering precision to deliver a wheel that performs unlike any made before. This patented new rim shape achieves something conventional aero wheels cannot; it simultaneously reduces both aerodynamic drag and side force for the ultimate in AeroBalance?. Sawtooth? accomplishes this with a series of patented fin-shaped Hyperfoil? nodes along the inner diameter of the rim that work together with our new HexFin? ABLC dimples for improved airflow. The result is Zipp?s highest performing wheelset ever realized with both aero-drag reduction and reduced side force at all wind yaw angles. This is important because higher wind yaw angles are where bike handling is most affected by the wind.
Hyperfoil? is the name given to the individual nodes on Zipp NSW variable depth Sawtooth? rims. Each of these patented structures features our HexFin? ABLC dimples that help to stabilize handling in gusting wind by increasing wind vortex shedding frequency. The higher frequency vortex shedding produced by Sawtooth? creates a greater number of smaller, less powerful, yet more predictable vortices leading to greater wheel stability. This added stability translates into greater rider control, thereby saving energy that is typically expended trying to hold a line in gusting wind. The result is a faster, more confident riding experience whether you are laying down power or descending sinuous mountain roads.
HexFin? ABLC dimples are the hexagonally shaped depressions found at each Hyperfoil? of our Sawtooth? shaped NSW rims. The angular shape of each dimple increases boundary layer mixing to help keep airflow attached to the rim for reduced aerodynamic drag and improved stability in crosswinds. To further improve the effectiveness of the hexagonal dimples, they are arranged in fin-shaped clusters made up of variable sized dimples that work in concert with each Hyperfoil? of a Sawtooth? rim.
Zipp has employed the ImPress? graphics technology, which prints graphics directly on the wheel, to help allow the dimples to do what they were design to do ? help control vortex shedding, the rate at which air sheds off the wheel. Managing this is crucial to stability. ImPress graphics also give NSW a distinctive stealthy look. Zipp 454 NSW Carbon Clincher Zipp Cognition Hubset with Axial Clutch Technology Zipp NSW
