PROBLEM TO BE SOLVED: To provide a golf club excellent in carry performance.SOLUTION: A club 2 includes a head 4, a shaft 6, and a grip 8. A club length L1 is 43 inches or more and 48 inches or less. A ratio (Wh/Wc) between a head weight Wh and a club weight Wc is equal to or greater than 0.70. The moment of inertia Ix about a swing axis is 6.90×10(kg cm) or more and 7.50×10(kg cm) or less. A static moment Mt (kg cm) of the club is equal to or greater than 16.3 (kg cm). A club frequency is 240 (cpm) or more and 280 (cpm) or less. The moment of inertia Ix (kg cm) is calculated by a formula (1) defined by Ix=Wc×(Lc+60)+Ic. |
