  • Cycling aero foil system
    Patent number: 11198323
    Abstract: The coefficient cycling aero foil system is designed to reduce drag and turbulence from a tire and spokes used to support a bicycle wheel. The system is integrated into a rim on a bicycle wheel which allows for increased forward momentum by cutting drag and reducing wheel turbulence that occurs during the rotation of a bicycle wheel. The foils may be strategically placed for optimum aerodynamic wind flow and are precisely angled to force wind past the foil creating increased forward momentum.
