Abstract

Golf club, golf club shaft and golf club head structures are presented. The golf club may include an adjustable shaft configured to be received in a slot formed in a crown of the golf club head. In some examples, the slot may include a plurality of receivers, such as apertures, configured to receive the shaft in various positions along the length of the slot. The various positions may be progressively closer to a central area of the ball striking surface in order to increase the power transferred to the ball upon striking it.
