<p>PROBLEM TO BE SOLVED: To derive conditions of an optimum club mass distribution while taking club lengths into consideration and to provide a golf club and golf club set embodying the same. SOLUTION: A shaft is basically constant in line density and the line density of part of 0.322 to 0.605 m from the top end of the grip (a range of 30% of the club length around the position of 48% of the club length from the top end of the grip) is set higher by about 20% than other parts.</p> |
