Abstract

A titanium bodied driver that utilizes a lightweight receiving back cap, which is designed to be non-removable from the club head but can be loosened to allow its interior to be accessed to reposition one or more movable weights into alternative receiving locations, is disclosed herein. The back cap may also be designed to be completely removable from the driver body to gain access to the one or more weights that can be re-positioned in alternative receiving areas within the back cap's interior.
