<p>PROBLEM TO BE SOLVED: To correct a slice neither too much nor too little. SOLUTION: When the bending twist quantity of the shaft of a golf club formed by combining the shaft for the golf club which bends and simultaneously twists and a head is defined as Y ( deg.) and the centroid distance of the head which is the distance between the centroid point of the head and the axis of the shaft is defined as X (mm), the relation of X and Y is so set as to satisfy Y=0.1X-a(1.0<=a<=3.0 30<=X<=46).</p> |
