<p>PROBLEM TO BE SOLVED: To eliminate a problem of the stabilization/orientation in a change of the gravity center of a golf club head. SOLUTION: For this golf club set, a weight adjustment is optimally performed for each number of golf clubs from a long to a middle and to a short by a weight and a push-out rotating effect of the gravity center. In this case, the weight changes the gravity center of the golf club head from the depth side to the upper side, and from the upper side to the front side.</p> |
