A golf club fitting apparatus and a grip for helping with golf club alignment are provided. The golf club fitting apparatus may be attached to a golf club and provide fitting information including effective lie angle and effective loft angle. An angle indicator is disposed at a predetermined angle relative to a shaft axis of the golf club so as to rest in a neutral position when the golf club is in a normal address position. A grip is provided that may be attached to a golf club shaft such that a butt end and/or distal end of the grip have a surface that helps with golf club alignment. A grip is provided with a front portion having edges that help with golf club alignment.

Methods of manufacturing a golf club head with one or more stiffening members proximate the face, and particularly solid rods or a plate with one or more cutouts, is disclosed herein. One method includes the steps of preparing a wax mold of a golf club head including a plate stiffening member with excess material, casting the golf club head, and machining away the excess material. Another method includes the steps of casting a golf club body, providing a plate stiffening member, providing a face component such as a face cup, tack welding the plate stiffening member and the face component to the golf club body, and welding these parts together.

A golf club head includes a golf club body including a crown, a sole, and a skirt connected between the crown and the sole, the golf club body including a front including a leading edge and a back including a trailing edge, and a hosel connected to the golf club body; a face connected to the front of the golf club body, the face including a geometric center, the golf club head including modifiable boundary conditions.

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.

An interchangeable and weight adjustable golf grip including at least an end cap body having integral receiving ports adapted to receive variable weights, electronic chips, sensors, gauges, lasers, cameras, or biometrics within and wherein the end cap is capable of housing the various weights, chips, sensors, etc. within the end cap so that a player can interchange the weights or sensors without removing the golf grip from the shaft in order to make adjustments and so that the player can play golf without removing any other portions of the grip. Further, the invention includes contemplation of a tip collette with integral receiving ports adapted to also harbor similar weights, or sensors, etc. Data from the sensors may be transmitted by Bluetooth transmission to a smartphone or a ball launch monitor system for analysis.

Articles of sports equipment, such as striking implements (e.g., sticks) and wearable articles (e.g., skates, helmets) for playing hockey or other activities, in which at least one of the characteristics (e.g., stiffness) of the articles of sports equipment is adaptable and can be altered during use of the sports equipment, such as by comprising an alterable component coupled to a controller, by comprising an alterable component that is autonomously alterable, and/or by an alterable component that can be altered in response to a command of a remote device.
