Abstract: A golf club includes a golf club head, a shaft adapter secured within a hosel of the golf club head, and a shaft secured within the shaft adapter. The golf club shaft is formed from a fiber reinforced polymer and extends along a longitudinal axis between a tip end and a grip end. The golf club shaft includes a tip end section, a grip end section, and a tapered section between the tip end section and the grip end section. The tapered section of the shaft includes a reference portion within the upper half that has a frustoconical shape with a near-constant taper rate, and a narrowed portion within the lower half. The narrowed portion is recessed relative to a reference surface extrapolated from the frustoconical shape.

Abstract: Some embodiments include a golf club head. The golf club head includes a front body having a front body front portion with a front body front surface and having a front body rear portion, and includes a rear body having a rear body front portion, a rear body rear portion, and multiple protrusions. The golf club head is configured such that (i) when the front body front surface strikes a golf ball with a first amount of force, the front body deflects toward the rear body with a first amount of deflection, and (ii) when the front body front surface strikes the golf ball with a second amount of force less than the first amount of force, the front body deflects toward the rear body with a second amount of deflection greater than the first amount of deflection. Other embodiments of related club heads and methods are also disclosed.
