Abstract
A golf club shaft is provided with increased torsional stiffness by making the outside diameter of the tip end larger. The torsional stiffness per unit weight of the shaft is greater than the torsional stiffness per unit weight of prior shafts. The shaft can be attached to a clubhead by inserting the tip end over a male hosel or over a shaft adapter which is attached to a female hosel.
