Abstract

A golf club head comprising a channel and an expandable weight that can be removably fixed at any point within the channel is disclosed herein. The weight comprises at least an upper portion, a middle portion, a lower portion, and a bolt, and the upper portion and lower portion preferably are formed of metal materials while the middle portion preferably is formed of a polymeric material. The weight preferably is trapped within the channel so that it cannot fall out of the channel during use. The channel may also have an end that opens into a port, which can be filled with a plug or weight screw to prevent the weight from falling out of the channel, and also can be removed so that the weight can be removed and replaced with another expandable weight having a different overall mass.
