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 lower portion, and a bolt, and preferably is formed of a metal material co-molded with a polymeric material such as rubber. The channel has an opening with a width that is less than the width of both an inner part of the channel and the weight, such that the weight 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.
