Abstract
Abstract A golf club comprising a shaft made of a composite material with a head (2) at its lower end and a grip (3) at its upper end. The shaft comprises three distinct sections, namely (a) a first, upper tapered portion (12a) covered by the grip, (b) a second, lower portion (12b) extending to the lower portion (10) of the shaft, and (c) a third connecting portion attaching the first to the second portions. The diameter (d1) of the section of the lower end of the first portion (12a) is smaller than the diameter (d2) of the section of the upper end of the second portion (12b).
