A golf club including a grip, shaft and clubhead is modified by a variable flexure mechanism so that the flexibility of the shaft can be changed. The flexure mechanism increases or decreases the shaft flexibility by varying the tension in a wire extending between the club handle and the club head. The wire is held at a spaced relationship from a shaft of the club by a bridge which maximizes the effect of the small changes in tension in the wire, according to movement of a threaded connection between the wire and the club head. Increasing the tension in the flexure adjustment mechanism decreases the flexibility of the shaft and decreasing the tension increases the flexibility of the shaft. The golf club is used in a method to customize golf clubs for a given golfer by first establishing the golfer's clubhead speed and then correlating that clubhead speed to required club flexibility. The adjustable flex club is adjusted to the flexibility required and then used as a basis upon which other golf club shafts are matched to an individual golfer.
