摘要： Disclosed is a golf club set having harmonized golf club performance among the club numbers. In the golf club set, for at least three golf clubs, a ratio or a sum of a frequency per unit time, the frequency being measured by vibrating a tip portion of a golf club shaft constituting each of the golf clubs, and a frequency per unit time, the frequency being measured by vibrating a rear end portion of the golf club shaft, is determined in relation with order of the club number.

摘要： A golf club is evaluated by measuring a moment of inertia about an axis perpendicular to a face plane of the golf club head through a center of a mass of the golf club head. The golf club has the evaluation imparted by a moment of inertia information relating to a value of the moment of inertia or a value obtained by dividing the moment of inertia by a mass value of the golf club head. A golf club set is composed of at least three golf clubs having different loft angles and each of the golf clubs has the size of the moment of inertia adjusted corresponding to an order of golf club number or an order of a value of the loft angle. The moment of inertia changes linearly corresponding to the order of the golf club number or the loft angle.
