ABSTRACT:
A golf club shaft having a spar, a tube, and a skin is formed which reduces shaft aerodynamic drag. The skin transforms in cross-sectional shape from a circular one at the grip, to a streamlined shape at the shaft tip. The spar introduces stiffness in the plane generally perpendicular to the direction of swing, thereby offsetting the effect of unequal sectional moments of inertia of the streamlined skin. Manufacturing methods are also disclosed.
