A golf club head includes a metal frame having a sole opening, a composite laminate crown joined to the frame, a composite laminate sole insert joined to the frame and overlying the sole opening, and a thermoplastic composite component overmolded on the sole insert. The composite component may include a weight track, ribs, supports or other features. A method of making the golf club includes the steps of forming a frame having a sole opening, forming a composite laminate sole insert, forming a composite laminate crown insert, injection molding a thermoplastic composite head component over the sole insert to create a sole insert unit, and joining the sole insert unit and crown insert to the frame.

Methods and systems for detecting configuration states of a golf club and adjustment systems of a golf club, such as a shaft connection system. A golf club configuration detection system captures configuration data from the adjustment system of the golf club by a configuration detection device, such as a camera, a barcode scanner, or an RFID scanner. The captured configuration data is compared to reference configuration data to determine a configuration state of the adjustment system. Swing data and ball-flight data are tracked for golf-ball strikes with the golf club in the detected configuration state. Recommendations for configuration states may be generated based on the tracked data.

A golf club head includes a body defining an interior cavity. The body includes a sole positioned at a bottom portion of the golf club head, a crown positioned at a top portion, and a skirt positioned around a periphery between the sole and crown. The body has a forward portion and a rearward portion. The club head includes a face positioned at the forward portion of the body. In some embodiments, the crown includes a lattice-like structure having thin regions surrounded by a web of relatively thicker regions. In some embodiments, the club head includes one or more stiffening tubes attached between the sole and the crown to improve the acoustic performance of the golf club head.

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.

A golf club head includes a metal frame having a sole opening, a composite laminate crown joined to the frame, a composite laminate sole insert joined to the frame and overlying the sole opening, and a thermoplastic composite component overmolded on the sole insert.

A golf club includes a striking face, a top portion, a sole portion opposite the top portion, and a shaft assembly. The shaft assembly can include a shaft having a butt end and a tip end, and a shaft sleeve located at the tip end, the shaft sleeve including indicia. The golf club may further include a hosel extending from the top portion, and the hosel can include a sidewall, a tip end, an internal bore for receiving the shaft assembly, a hosel axis, and an aperture extending through, and circumscribed by, the sidewall such that the indicia of the shaft sleeve corresponds with the aperture. The sidewall circumscribing the aperture may include an inner surface having a first thickness T1 in a radial direction relative the hosel axis and a chamfered edge having a second thickness T2 in the radial direction, T1/T2 being between approximately 3 and 7.33.

Disclosed herein is a golf club head comprising at least one crown opening and at least one crown insert attached to the body and covering the at least one crown opening. The golf club head further comprises at least one sole opening and at least one sole insert attached to the body and covering the at least one sole opening. The golf club head additionally includes at least one weight member configured to clamp first and second ledges at selected locations along a sliding weight track. The golf club head also comprise a coefficient of restitution (COR) feature located on the sole of the golf club head. The at least one crown insert is formed from a composite material having a density between 1 g/cc and 2 g/cc. The at least one sole insert is formed from a composite material having a density between 1 g/cc and 2 g/cc.
