A golf club head having a hosel, a hollow interior, and a support structure disposed within the hollow interior proximate a flange region is disclosed herein. In particular, the present invention is directed to a fairway wood head comprising a body with a front wall, an upper opening, a return portion between the front wall and the upper opening, a hosel, an interface between the hosel and the heel side of the body, and a hosel support ring or support rod, and a composite crown affixed to the body to close the upper opening and define a hollow interior. The support structure reduces the stresses placed on, for example, the crown during hosel bending processes.

A golf club head having a hosel, a hollow interior, and a support ring disposed within the hollow interior and at least partially encircling the hosel is disclosed herein. In particular, the present invention is directed to a fairway wood head comprising a body with a front wall, an upper opening, a return portion between the front wall and the upper opening, a hosel, an interface between the hosel and the heel side of the body, and a support ring, and a composite crown affixed to the body to close the upper opening and define a hollow interior, the support ring contained within the hollow interior and extending along the interface from a heel-most side of the body to the return portion and making contact with an inner surface of the front wall. The support ring reduces the stresses placed on, for example, the crown during hosel bending processes.

A golf club head comprising a channel or a pair of parallel rails and a slidable weight assembly that can be removably fixed at any point within the channel or to the rails is disclosed herein. The slidable weight assembly preferably comprises a weight portion and base that can be turned 45 to 90 degrees to reversibly fix the slidable weight assembly within the channel or to the rails.
