<p><P>PROBLEM TO BE SOLVED: To adjust the carry and the controlability with a smooth rotation force by optimizing the position of each center of gravity by heightening the center of gravity of the head of the long golf club and adjusting the sole, lowering the center of gravity to the top of the shaft of the golf club, and combination with lowering of the center of gravity to the top of the grip of the golf club. <P>SOLUTION: The center of gravity is heightened by increasing the weight of a crown part and a weight in a sole part is minutely adjusted for the stabilization of a lateral shaft optimal for the head of the long golf club and the optimal adjustment of the loft angle at the time of impact. The balance of the position of the center of gravity and the total weight is adjusted by heightening the center of gravity of a hosel part, adjusting the weight, and adjusting the angle of the sole. Further, synergic effects on the carry are achieved by adding the tendency to the lowered center of gravity to the top of the shaft and the grip of the golf club. <P>COPYRIGHT: (C)2004,JPO</p> |
