Abstract:
The subject golf clubs have a shaft and clubhead. The shaft has a tip-end coupled to the clubhead, a butt-end, a reduced-EI portion located adjacent the tip-end, and a remaining portion extending between the butt-end and the reduced-EI portion. The portions are coupled together at an interface. The remaining portion exhibits a respective rate of stiffness reduction as a function of distance from the butt-end. The reduced-EI portion is typically shorter than and has less stiffness than the remaining portion. The reduced-EI portion exhibits a respective rate (which can be zero) of stiffness reduction as a function of distance toward the tip-end. These rates can be similar or different. The interface can exhibit a greater rate in stiffness reduction than the other portions.
