ABSTRACT:
A golf club 10 includes a shaft 12 with a grip 18 assembled on a butt end 20 of the shaft. A club head 22 is mounted on a tip end 24 of the shaft 12. The shaft 12 is composed of a non-metallic material, such as fibers in a cured plastic matrix, and is formed with an tapered intermediate section 26. The section 26 includes two segments 28 and 30 which taper at different taper rates. A bulge 32 is formed in the shaft 12 near an inboard extremity of the tip end 24. The bulge 32 is formed with a central cylindrical section 34 and transition sections 36 and 38 on opposite axial ends of the central section. The diameter of the bulge 32 at any cross section thereof is greater than the diameter of the immediately adjacent portions of the shaft 12. Also, the bulge 32 is formed with an axial opening 16, the diameter of which is less than the diameter of the immediately adjacent portions of the shaft 12.
