Patent ID: 11040257

Abstract:
A golf club includes a head; a shaft; and a grip. The head has a weight Wh of greater than or equal to 195 g. The golf club has a club length Lc of greater than or equal to 45.0 inches. The golf club has a club weight Wc of greater than or equal to 295 g. The golf club has a swing moment of inertia Isw of less than or equal to 5470×103 (g·cm2). The swing moment of inertia Isw (g·cm2) is calculated by the following formula (1): Isw=Wc×(Lg+40)2+Ic  (1), where Wc represents the club weight (g), Lg represents a distance (cm) in an axial direction between a butt end of the grip and a center of gravity of the golf club, and Ic represents a moment of inertia (g·cm2) of the golf club about the center of gravity of the golf club.
