ABSTRACT:
An improved composite golf club shaft and method for its manufacture, and an improved club incorporating the shaft. The shaft includes a first elongate segment for mounting the golf club head and a second elongate frustoconical segment for gripping. The first segment is formed by wrapping sheet material around a substantially cylindrical mandrel, and the second elongate frustoconical segment is formed therearound to produce a smoothly tapering exterior surface of the shaft having an abrupt interior region of joinder between the segments. Such joinder preferably is approximately one-third of the way between the gripping end and the head-mounting end of the shaft. The shaft tapers such that its head-mounting end is less than approximately one-third the diameter of the gripping end. Greatly improved torque and drive distance are achievable with a club made with the shaft. The shaft is also lighter and capable of being used without the addition of a grip. As a result, the balance point of the club is much closer to the head of the club than before possible, further improving the performance characteristics of the club.
