摘要 A golf club having a value of L not less than 45.5 inches, with L representing a club length measured with a 60-degree method, includes a shaft, a grip attached to one end of the shaft, and a head attached to the other end of the shaft. A value of r/L is equal to or not smaller than 0.658 and equal to or not greater than 0.732, where r represents a distance from an upper end of the grip to the center of gravity of the golf club.
