[Problem] To provide a golf club grip having excellent anti-slipping performance, and feeling when the grip is wet, and further to provide a golf club grip having excellent durability and an improved head speed. [Solution] The golf club grip comprises a cylindrical portion for inserting a shaft, wherein the golf club grip has a narrow groove region comprising narrow grooves in an occupation ratio of 35% or more per 25 mm.sup.2 at at least a part of a surface of the cylindrical portion, and the narrow groove has a width (w) of from 0.1 mm to 0.7 mm and a depth (h) of from 0.1 mm to 1.0 mm. In addition, an interval (d) between the narrow grooves are preferably 1.5 mm or less.

The inventive fiber manufacturing process is particularly adapted for demanding applications such as sports racquets, including tennis racquets, badminton racquets and other sports applications. Because of the improved strength to weight ratio of components formed using the inventive method, a wide range of flexibility is achieved, allowing use of the inventive process to manufacture, for example, a fiber reinforced (for example, graphite) modular sports racquet, optionally provided with user-selectable weights and/or handle replacements. From the standpoint of the player, this allows a racquet frame featuring self customization. From the standpoint of a retailer, the benefit provided is reduction of inventory. The inventive fiber, for example graphite fiber) racquet frame is filled with a plastic foam and is formed using, for example, microencapsulation technology to time, generate and apply the pressure used to form the graphite composite material of which the racquet is comprised. Advantageously, inner and outer tubular members may be used to form the racquet frame, with the inner tubular member extending around the head of the racquet frame. This compares to the standard industry technique of air injection. The racquet is thus not hollow like conventional graphite racquets, and the walls therefore can be made thinner than those of existing graphite racquets still being of the same strength or being stronger, which gives the racquet exceptional performance. In addition, the overall dimensions of, for example the cross-section, of the racquet can also be reduced while still maintaining performance characteristics.

A golf club tracking assembly includes a plurality of golf clubs and a golf bag for storing the golf clubs. A personal electronic device is provided that has wireless communication capabilities. A plurality of tracking units is each attached to a respective one of the golf clubs. A base unit is integrated into the golf bag and the base unit is in remote communication with the personal electronic device thereby facilitating the personal electronic device to download the number of tracking units that is assigned to the golf bag. The base unit is in remote communication with each of the tracking units and the base unit generates an alert when the base unit ceases communicating with any of the tracking units. In this way a user is alerted that one or more golf clubs is missing from the golf bag to inhibit the golf clubs from being lost or misplaced.

Examples of golf club shafts and methods to manufacture golf club shafts are generally described herein. In one example, a golf club shaft includes a first tubular portion formed from a first material and coupled to a second tubular portion having a plurality of layers formed from a second material and a third material. A reinforcing member is disposed in at least one of the plurality of layers and is formed from a fourth material. The reinforcing member extends a length that is less than or equal to a length of the second tubular portion. The first, second, third, and fourth materials are different from one another. Other examples and examples may be described and claimed.

There is herein described a range of sporting products comprising sucker elements, which can be used in various uses such as on products which require, for example, hand or any other type of grip contact. The grip contact may be with the feet or hands (or any other part of the body). The sporting products that the grips may be used on may comprise rackets (e.g. for tennis/badminton/squash etc.), bats (e.g. cricket/baseball/table-tennis etc.), bicycles, motorcycles, golf clubs, water sports (surfing, windsurfing) etc. The sucker elements may also be included with other sporting product such as on the inside and/or outside of running sock or shoes for example. There is also described a range of industrial products comprising sucker elements which can be used in a range of applications such as on a range of vehicle parts (e.g. bus rails, train rails, boat rails, steering wheels, motorbike handles and foot pegs etc.), industrial machinery (e.g. handles for tools such as drills, pneumatic drills etc.), flooring (e.g. decking on boats and in industrial environments), crockery, bathroom and shower flooring, and surfaces to aid disabled people.

A golf club grip may include a docking tube and an elongated handle. The docking tube may be configured to couple to a golf club shaft and may include a docking tube sidewall. The elongated handle may be detachably couplable to the docking tube. The elongated handle may include an elongated handle sidewall defining an axial opening configured to receive the docking tube. At least one of the docking tube sidewall and the elongated handle sidewall may include a projection and the other of the docking tube sidewall and the elongated handle sidewall may include a channel. The channel may be configured to receive the projection to prevent rotation of the elongated handle relative to the docking tube when the elongated handle is coupled to the docking tube.
