Golf club head with adjustable center of gravity
A golf club head comprising multiple means of adjusting the location of the center of gravity, and the bias, is disclosed herein. In a preferred embodiment, the golf club head comprises a non-metal medallion comprising a channel that is affixed to one of the crown and the sole, a slidable weight sized to fit within the channel, and a cover that attaches to the medallion and locks the slidable weight within the channel at a location selected by a user. The cover preferably includes at least one cutout so that the slidable weight is at least partially visible to the user when it is locked within the channel. The cover also includes additional cutouts that receive protrusions extending from the medallion to more securely attach the cover to the medallion.
