For decades, the golf industry has confined a golfer’s swing within a few simple alphabet letters such as R (Regular) and S (Stiff).
However, this is a fundamentally irresponsible approach from a physics standpoint. Even within the same “S” flex category, standards vary by manufacturer, and the overall bend profile of the shaft differs dramatically.
Conventional methods that merely measure frequency (CPM) or overall stiffness fail to explain how the shaft responds at each phase of the swing.
KGST rejects such illusory classifications and traces the precise physical metrics hidden behind the golfer’s vague perception of “stiffness,” exposing the limitations of traditional fitting systems.
Within the boundaries of regulation, golfers remain trapped in stagnant performance.
