autoFlex Original
A new-concept shaft that changes what you know about shafts
Shaft type: driver / wood, utility / hybrid, iron
The birth of an astonishing, never-before-imagined shaft – autoFlex is the real thing. A new-concept shaft that changes conventional wisdom about shafts, built on Korean technology (Korea Hidden Technology).
autoFlex features
- A fusion of new materials makes it 20–30 g lighter than conventional shafts, reducing strain on the body.
- autoFlex shafts automatically adjust their stiffness to the golfer’s swing.
- Paradoxically, lightness and softness become the driving force for hitting stronger and farther.
- Swing with the feeling of pushing through the ball and experience autoFlex’s unique performance: maximum contact between ball and clubhead.
