A golf club comprises a shaft, a club head, and a connection assembly that allows the shaft to be easily disconnected from the club head. In particular embodiments, the connection assembly includes a removable hosel sleeve that allows a shaft to be supported a desired predetermined orientation relative to the club head. In this manner, the shaft loft and/or lie angle of the club can be adjusted without resorting to traditional bending of the shaft. In another embodiment, the club head has an adjustable sole that can be adjusted upwardly and downwardly relative to the strike face of the club head, which is effective to adjust the face angle of the club head.
