A golf club head has a face portion, a crown portion, and a sole portion. The golf club head includes a weight member that is configured to be wound, a first wound portion around which a first part of the weight member is to be wound, and a second wound portion that is disposed apart from the first wound portion and around which a second part of the weight member is to be wound. In the golf club head, a position of a center of gravity of the golf club head is adjusted by changing a weight ratio of the first part to the second part. At least either the first wound portion or the second wound portion may be rotatable in a reel-in direction and a reel-out direction.

Embodiments of golf club heads with apertures and methods to manufacture golf club heads are generally described herein. In some embodiments, a golf club head comprises a face portion, a back portion generally opposite the face portion, a heel portion extending between the face portion and the back portion, a toe portion opposite the heel portion and extending between the face portion and the back portion, and a crown portion extending between the face portion, the back portion, the heel portion, and the toe portion, the crown portion comprising a plurality of crown aperture. The crown portion comprises a first region and a second region, wherein the first region is nearer to the face portion than the second region, the first region and the second region are separated by a bell-shaped curve. The bell-shaped curve is located a distance D1 from the face portion and the second region comprises a recess portion. The plurality of crown apertures is defined within the recessed portion. In some embodiments, the golf club head comprises both metal and fiber-based composite portions. In other embodiments, the golf club head comprises a plurality of sole apertures. Other embodiments may be described and claimed.

A golf club head includes a club body having a crown opposite a sole, a toe end opposite a heel end, a back end, and a hosel. A first magnet is coupled to the club body. A second magnet selectively engages the first magnet, such that in a first configuration the first and second magnets attract, and in a second configuration the first and second magnets do not attract, wherein the second magnet is configured to rotate relative to the first magnet between the first configuration and the second configuration.

A golf club head having a golf club head body and an inner wall structure. The club head body includes a back portion, a striking face, a sole, and a topline. The inner wall structure is at least partially in contact with a rear surface of the striking face. The inner wall structure also has a fixed end and an unfixed end. The golf club head is also configured such that the portion of the inner wall structure in contact with the rear surface of the striking face may slide against one another. The golf club head may also include a sole channel, and the fixed end of the inner wall structure may be attached to either a front edge or back edge of the sole channel.

A carbon-fiber composite golf club head comprises a carbon-fiber composite body, at least one carbon-fiber composite component and at least one weight component. The carbon-fiber composite body comprises a hollow body portion, one-piece formed by stacking carbon fiber prepreg materials, and a striking face portion disposed at a front end of the body portion. The at least one carbon-fiber composite component is mounted to at least one opening of one or both of a crown and a sole of the body portion. The at least one weight component is mounted at a rear end of the carbon-fiber composite body. By combining the carbon-fiber composite body, one-piece formed by carbon fiber composite material and comprising the body portion and the striking face portion, with the at least one carbon-fiber composite component, a weight of a main part of a club head is significantly reduced to increase a weight of counterweight.
