This study compared and evaluated the characteristics of golf driver shafts 60R products, manufactured by the most-usedthree companies and a domestic company adopting a new material process technology in the world. The characteristics ofdriver shafts were evaluated by observing the variations in golf shafts at an impact, which is known to influence drivingdistance and directional nature, by using a strain gage and a swing machine. Experiment results on four driver shafts showedthat each shaft had different degree of deformation at an impact and formed different pattern at each position. Shafts ofAutopower, Tour AD MT, and Fujikura showed an arch shape at an impact in overall. However, those of Attas revealed letterS shape. Under the test condition, Autopower shafts showed relatively higher bending stiffness and had the largest impulseon a ball. So it was expected that they would increase the ball speed after an impact.
