ABSTRACT:
In a fibre-reinforced plastic golf club shaft, which has at the bottom an end portion for attaching a club head and at the top an end portion for attaching a grip and which is constructed in the form of a hollow profile. The cross-section of the profile is not constant over the shaft length and is provided with a shape, which is symmetrical to a median plane passing through the longitudinal axis of the shaft in the driving direction. The flex point of the shaft is in the area between the two end portions.
Over the shaft length, the shaft has a cross-sectional configuration such that, starting from the flex point and passing towards each of the two end portions, the resisting moment of the cross-sectional surface of the shaft at right angles to the median longitudinal axis relative to the axis passing through the median longitudinal axis of the shaft and at right angles to the golf club driving direction decreases with increasing distance from the flex point (F) until reaching a minimum resisting moment on entering the particular end portion or close to the latter.
