<p>PROBLEM TO BE SOLVED: To provide a shaft set for simply producing a golf club set capable of swinging all the clubs in the same timing by nearly equalizing the inertia moments of the respective clubs. SOLUTION: In this shaft set for golf club set consisting of plural clubs gradually increasing the weight of a head and gradually reducing the length of a shaft as the increase of the numeral figure of a number, the shaft set for a golf club set consisting of iron clubs gradually reduces the inertia moment of the shaft within the range of 5 to 9% according to the increase of the numeral figure of the number by one and a shaft set for a golf club set consisting of wood clubs gradually reduces the inertia moments of the shaft within the range of 2 to 4% according to the increase of the numeral figure of the number by one.</p> |
