1. A golf club head comprising:

  • a body having a face, a crown, a hosel, and a sole together defining an interior cavity;

    the body having a channel located on the sole;

    first and second opposing ledges extending within the channel;

    at least one weight member movably positioned within the channel such that a position of the at least one weight member within the channel is able to be adjusted, thereby adjusting a location of a center of gravity of the club head;

    the at least one weight member comprises an outer member engaging an outward-facing surface of the first and second ledges, an inner member engaging an inward-facing surface of the first and second ledges, and a separate fastening bolt comprising an enlarged head portion and a threaded shaft extending from the head portion, the inner member includes a threaded bore for receiving the shaft, and the outer member comprises a non-threaded bore for receiving the shaft and a counter-bore in communication with the non-threaded bore for receiving the enlarged head portion;

    wherein the shaft of the fastening bolt is configured to be inserted through the non-threaded bore of the outer member and tightened into the threaded bore of the inner member to cause the inner member and the outer member to clamp onto opposite sides of the first and second ledges;

    wherein the outer member comprises a central protrusion that extends into a space between the first and second ledges, the outer member further comprising first and second recessed surfaces on opposite sides of the central protrusion, the first recessed surface being configured to contact the first ledge and the second recessed surface being configured to contact the second ledge;

    wherein the first and second ledges extend within the channel from a heel end of the body to a toe end of the body;

    wherein the face includes a center face location that defines the origin of a coordinate system in which an x-axis is tangential to the face at the center face location and is parallel to a ground plane when the body is in a normal address position, a y-axis extends perpendicular to the x-axis and is also parallel to the ground plane, and a z-axis extends perpendicular to the ground plane, wherein a positive x-axis extends toward the heel end of the body from the origin, a positive y-axis extends rearwardly from the origin toward the interior cavity, and a positive z-axis extends upwardly from the origin toward the crown;

    wherein adjustment of the at least one weight member provides a maximum x-axis adjustment range of the position of the center of gravity (Max Δ

    CGx) that is greater than 2 mm;

    wherein the weight member has a mass (MWA) and wherein the product of MWA*Max Δ

    x is between 250 g·

    mm and 4950 g·

    mm;

    wherein the product of MWA*Max Δ

    y is between 0 g·

    mm and 1800 g·

    mm; and

    wherein the center of gravity of the club head has a z-axis coordinate (CGz) that is less than 0 mm.
