A golf club (10) comprises a shaft (20) formed of a plurality of co-axially disposed tubes (21, 22) connected to one another at a stabilising joint or joints. Shaft (20) has an upper section forming a grip (24) and a lower section connected to club head (50). Tubes (21, 22) are parallel-sided and of differing cross-sectional sizes. The lower section is constituted by the tube of smallest cross section. The relative diameters of the tubes (21, 22) are such that the upper end of a tube is receivable within the bore at the lower end of its neighbour. Preferably, the material from which tubes (21, 22) are formed is selected from: (a) a titanium alloy; (b) a combination of (i) an extruded polymeric matrix reinforced with continuous, straight, pre-stressed and tensioned carbon fibres (26), said fibres (26) being aligned with the longitudinal axis of shaft (20), and (ii) continuous filament windings (27) that are also pre-stressed, tensioned and unbroken, or (c) a combination of materials from categories (a) and (b). |
