Golf club head with improved inertia performance and removable aft body coupled by snap fit connection

A golf club comprised of a golf club head, a shaft having a shaft axis coupled to said golf club head at a first end of said shaft and a grip coupled to said shaft at a second end of said shaft, wherein said golf club head comprises:

• a frontal portion comprised of a first material having a first density, said frontal portion comprising:
• a striking face having a face center located at a forward portion of said frontal portion;
• a crown return at an upper portion of said frontal portion;
• a sole return at a lower portion of said frontal portion;
• and
• a rear circumferential attachment edge,
• wherein said rear circumferential attachment edge of said frontal portion comprises at least one frontal cantilevered extension and at least one frontal elongate protrusion,
• wherein said at least one frontal cantilevered extension has a first height, and wherein at least one end of said at least one frontal cantilevered extension tapers to a second height that is less than said first height;
• and
• a rear portion comprised of a second material having a second density, said rear portion located aft of said striking face and comprising:
• a crown at an upper portion of said rear portion;
• a sole at a bottom portion of said rear portion;
• and
• a front circumferential attachment edge,
• wherein said front circumferential attachment edge of said rear portion comprises at least one rear cantilevered extension and at least one rear elongate protrusion,
• wherein said at least one rear cantilevered extension has said first height,
• wherein at least one end of said at least one rear cantilevered extension tapers to said second height that is less than said first height,
• wherein said rear portion is positionable in at least an unlocked configuration and a locked configuration relative to said frontal portion,
• wherein when said rear portion is in said unlocked configuration, said rear portion is freely movably relative to said frontal portion and offset from said frontal portion,
• wherein when said rear portion is in said locked configuration, said rear portion is removably coupled to said frontal portion and aligned with said frontal portion,
• wherein an x-axis is defined as a horizontal axis tangent to said face center with a positive x direction towards a heel of said golf club head, a y-axis is a vertical axis orthogonal to said x-axis with a positive x direction towards said crown, and a z-axis being orthogonal to both said x-axis and said y-axis with a positive z direction extending forward;
• and
• at least one first weighting member located near a central portion of said golf club head in a heel-to-toe orientation, substantially in line along said z-axis with said face center,
• wherein said at least one frontal cantilevered extension is configured to mate with said at least one rear elongate protrusion,
• wherein said at least one rear cantilevered extension is configured to mate with said at least one frontal elongate protrusion.

A golf club assembly comprised of a plurality of frontal portions each characterized by differences in geometry and/or inertial properties, a plurality of rear portions each characterized by differences in geometry and/or inertial properties, a golf club head constituted by one of said plurality of frontal portions coupled to one of said plurality of rear portions, a shaft having a shaft axis coupled to said golf club head at a first end of said shaft and a grip coupled to said shaft at a second end of said shaft,

• each frontal portion of said plurality of frontal portions is comprised of a first material having a first density, a striking face having a face center located at a forward portion of each said frontal portion, a crown return at an upper portion of each said frontal portion, and a sole return at a lower portion of each said frontal portion;
• and
• each rear portion of said plurality of rear portions is comprised of a second material having a second density, each said rear portion located aft of said striking face and comprising a crown at an upper portion of each said rear portion and a sole at a bottom portion of each said rear portion,
• wherein each said rear portion is positionable in at least an unlocked configuration and a locked configuration relative to each said frontal portion,
• wherein when each said rear portion is in said unlocked configuration, each said rear portion is freely movable relative to each said frontal portion,
• wherein when one rear portion of said plurality of rear portions is in said locked configuration with one frontal portion of said plurality of frontal portions, said one rear portion is removably coupled to said one frontal portion,
• wherein an x-axis is defined as a horizontal axis tangent to said face center with a positive x direction towards a heel of said golf club head, a y-axis is a vertical axis orthogonal to said x-axis with a positive x direction towards said crown, and a z-axis being orthogonal to both said x-axis and said y-axis with a positive z direction extending forward;
• and
• at least one first weighting member located near a central portion of said golf club head in a heel-to-toe orientation, substantially in line along said z-axis with said face center.
