PURPOSE: A golf club is provided to restrain the excessive flection of a shaft, thereby raising the speed of a head. CONSTITUTION: A golf club includes a shaft(3), a head(2) at the front end of the shaft, and a grip(4) at the rear end of the shaft. The weight of the club is 290 g or less, and the weight ratio of the head to the club is 0.67 to 0.72. When the inertia moment of the club at the end of the grip is MI, the range of the MI is 2700 kg·cm^2<=MI<=3000 kg·cm^2. When the frequency of the flexural vibration of the club is F, the range of the F is 190 cpm<=F<=230 cpm. |
