Abstract
A golf club head system and a golf club head for inclusion into a golf club are provided. The golf club head includes a main body member and a secondary body member. The main body member has a striking surface, a sole portion, a crown portion, and a rear face substantially opposed to the striking surface. The main body member defines an at least substantially enclosed main body cavity. The secondary body member is attached to the main body member and extends at least substantially over the entire rear face of the main body member. The golf club head system includes two or more secondary body members, each configured for interchangeable attachment to a main body member. Each secondary body member defines an internal concavity, has a different external shape, and has a different combination of center-of-gravity and moment-of-inertia characteristics.
