1. A golf club head comprising:
- a body having a face, a crown and a sole together defining an interior cavity, the body having a sliding weight track with first and second opposing ledges extending along the sliding weight track, wherein the first and second opposing ledges define a gap between the first and second opposing ledges;
at least one weight member configured to clamp onto the first and second opposing ledges at selected locations along the sliding weight track, wherein the at least one weight member is located entirely external to the interior cavity of the body and comprises an outer member, an inner member, and a threaded fastening bolt that connects the outer member to the inner member;
a weight installation cavity entirely located in a portion of the sliding weight track in which the first and second opposing ledges extend; and
a coefficient of restitution (COR) feature located on the sole of the golf club head;
wherein;
the weight installation cavity is configured to allow insertion of an entirety of the inner member into the weight installation cavity and the sliding weight track, through the gap defined between the first and second opposing ledges, in a direction that is not parallel to a longitudinal axis of the sliding weight track;
the weight installation cavity is defined by a recessed side surface of the sliding weight track to facilitate installation of the at least one weight member in the sliding weight track;
the recessed side surface is on only one side of the sliding weight track and located interiorly adjacent only one of the first and second opposing ledges; and
relative to a middle of the gap defined between the first and second opposing ledges, the sliding weight track is wider on the side of the sliding weight track that comprises the recessed side surface than on a side of the sliding weight track opposite the recessed side surface.

Abstract
A golf club head comprises a body having a face, a crown and a sole together defining an interior cavity. The body having a channel located on the sole and extending generally from a heel end of the body to a toe end of the body. A weight member movably positioned within the channel such that a position of the weight member within the channel is able to be adjusted, thereby adjusting a location of a center of gravity of the body. Additionally, adjustment of the weight member provides a maximum x-axis adjustment range of the position of the center of gravity (Max ΔCGx) that is greater than 2 mm and a maximum z-axis adjustment range of the center of gravity (Max ΔCGz) that is less than 2 mm.

10. A golf club head comprising:
-
a body having a face, a crown and a sole together defining an interior cavity, the body having a sliding weight track with first and second opposing ledges extending along the sliding weight track, wherein the first and second opposing ledges define a gap between the first and second opposing ledges; at least one weight member configured to clamp onto the first and second opposing ledges at three or more selected locations along the sliding weight track, the at least one weight member comprises an outer member, an inner member, and a threaded fastening bolt that connects the outer member to the inner member; a weight installation cavity entirely located in a portion of the sliding weight track in which the first and second opposing ledges extend, wherein the weight installation cavity is configured to allow insertion of an entirety of the inner member into the weight installation cavity and the sliding weight track, through the gap defined between the first and second opposing ledges, in a direction that is not parallel to a longitudinal axis of the sliding weight track and the inner member is noncircular and shaped to prevent rotation within the sliding weight track; a coefficient of restitution (COR) feature located on the sole of the golf club head; a heel opening located on a heel end of the body, the heel opening configured to receive a fastening member; and a head-shaft connection system including a sleeve that is secured by the fastening member in a locked position, the head-shaft connection system configured to allow the golf club head to be adjustably attachable to a golf club shaft in a plurality of different positions resulting in an adjustability range of different combinations of loft angle, face angle, or lie angle wherein; the weight installation cavity is defined by a recessed side surface of the sliding weight track to facilitate installation of the at least one weight member in the sliding weight track; the recessed side surface is on only one side of the sliding weight track and located interiorly adjacent only one of the first and second opposing ledges; and relative to a middle of the gap defined between the first and second opposing ledges, the sliding weight track is wider on the side of the sliding weight track that comprises the recessed side surface than on a side of the sliding weight track opposite the recessed side surface. - View Dependent Claims (11, 12, 13, 14, 15)

16. A golf club head comprising:
-
a body having a face, a crown and a sole together defining an interior cavity, a sliding weight track including first and second opposing ledges extending within the sliding weight track, wherein the first and second opposing ledges define a gap between the first and second opposing ledges; a weight installation cavity entirely located in a portion of the sliding weight track in which the first and second opposing ledges extend; at least one weight member movably positioned within the sliding weight track and configured to clamp onto the first and second opposing ledges at two or more positions along the sliding weight track; a coefficient of restitution (COR) feature located on the sole of the golf club head, wherein the COR feature is a through slot; a heel opening located on a heel end of the body, the heel opening configured to receive a fastening member; and a head-shaft connection system including a sleeve that is secured by the fastening member in a locked position, the head-shaft connection system configured to allow the golf club head to be adjustably attachable to a golf club shaft in a plurality of different positions, wherein an adjustability range of the head-shaft connection system includes different combinations of loft angle, face angle, or lie angle; wherein; at least a portion of the sliding weight track is located on a heel side of the body and at least a portion of the sliding weight track is located on a toe side of the body; movement of the at least one weight member produces a change in a head origin z-axis coordinate of a center of gravity of the golf club head of less than 1.0 mm throughout the adjustability range; the at least one weight member and the head-shaft connection system are configured to be adjustable by a single tool; over at least a portion of the sliding weight track a width of the sliding weight track is between about 8 mm and about 20 mm, and a depth of the sliding weight track is between about 6 mm and about 20 mm; the weight installation cavity is configured to allow insertion of the at least one weight member into the weight installation cavity and sliding weight track, through the gap defined between the first and second opposing ledges, in a direction that is not parallel to a longitudinal axis of the sliding weight track; the weight installation cavity is defined by a recessed side surface of the sliding weight track to facilitate installation of the at least one weight member in the sliding weight track; the recessed side surface is on only one side of the sliding weight track and located interiorly adjacent only one of the first and second opposing ledges; and relative to a middle of the gap defined between the first and second opposing ledges, the sliding weight track is wider on the side of the sliding weight track that comprises the recessed side surface than on a side of the sliding weight track opposite the recessed side surface. - View Dependent Claims (17, 18, 19, 20)
