  • Publication number: 20040229713
    Abstract: A golf club (40) having a club head (42) with a face component (60) and an interchangeable aft body (61) is disclosed herein. The face component (60) has a striking plate portion (72) and a return portion (74). The aft-body (61), which is attached to the return portion (74) of the face component (60), is selected from a plurality of aft-bodies, each having a different center of gravity location. Each of the aft-bodies (61) is composed of a crown portion (62), a sole portion (64), and at least one weight member (122) for adjusting location of the center of gravity. An aft-body (61) is selected from the plurality of aft-bodies (61) based on its center of gravity location, so as to provide the club head (40) with a center of gravity location suited to a particular golfer.
