A golf club head comprises a sole, a recessed sole port in the sole; and a rotatably adjustable sole piece adapted to be at least partially received within the sole port and comprising a central body having a plurality of contact surfaces adapted to contact the sole port and being offset from each other along a central axis extending through the central body of the sole piece. The sole piece can be positioned at least partially within the sole port at five or more rotational and axial positions with respect to the central axis, wherein at each rotational position, at least one of said contact surfaces of the central body contacts the sole port to set the axial position of the sole piece. The sole port and/or the sole piece can be generally pentagonal in shape.

Metal-wood type golf club heads having improved aerodynamic properties are disclosed. The golf club head includes a striking face; a sole connected to a bottom side of the striking face; a crown connected to a top side of the striking face; and an asymmetric hosel extending from the crown at a heelward side of the golf club head, the hosel including a hosel opening configured to receive a golf club shaft defining a shaft axis. The hosel includes at least one tripping structure on an exterior of the hosel. At the midpoint, a frontmost point of the exterior of the hosel is a distance DHF.sub.1/2 from the shaft axis; and at the midpoint, a rearmost point of the exterior of the hosel is a distance DHR.sub.1/2 from the shaft axis, the distance DHR.sub.1/2 is 25%-70% greater than the distance DHF.sub.1/2.

To obtain a golf club and a connecting member for a golf club shaft and a golf club head that can provide a flexibility in choice of reshafting to a user regardless of types of the golf club shaft and the golf club head and that can also provide excellent strength and/or appearance. A connecting member connects an inner-hosel-type golf club shaft and an over-hosel-type golf club head. The connecting member includes a hybrid structure combining different kinds of material.
