A cue for billiard sports that has a butt section, a joint collar, and a shaft section that has a kinetic energy absorbing insert located in the shaft section of the cue. A shaft section that has a kinetic energy absorbing insert that may be connected to an existing joint collar and butt section of a cue to improve the kinetic energy absorbing characteristics of the cue. A kinetic energy absorbing insert that is to be received by an existing shaft section of a cue in order to increase the kinetic energy absorbing characteristics of the cue is also disclosed.

A pool cue includes a butt having: an elongate central butt core, extending uninterrupted from a rearmost end of the butt to a foremost end of the butt; one or more oversleeves arranged about the central butt core and abutting one another; and a forward threaded butt connector positioned on the foremost end of the butt, the forward threaded butt connector operable to mate with a corresponding threaded shaft connector of a cue shaft. A shaft has: an elongate shaft sleeve, extending from a rearmost end of the shaft to a foremost end of the shaft; an elongate central shaft core, extending uninterrupted from the rearmost end of the shaft to the foremost end of the shaft; and a rearward threaded shaft connector positioned on the rearmost end of the shaft, the rearward threaded shaft connector operable to mate with the threaded butt connector.

A cue includes a shaft and an end piece. The shaft has a cavity at the position of a striking end of the cue, and the cavity extends along a longitudinal axis of the cue. The end piece includes a core situated in the cavity. The end piece includes at least two ribs which extend from the core in a direction radially of the longitudinal axis. The shaft includes at least two notches at the position of the cavity, each of which includes two opposite inner walls through which the at least two ribs extend at least partially. The side walls of the at least two ribs lie against the opposite inner walls so as to connect the end piece to the shaft.

An adapter assembly for use in the cue/billiards sports. The adapter assembly includes a first part, also referred to as a sleeve, and a second part, referred to as an adapter. The adapter assembly inserts into a hollow cue shaft. When the first end of the adapter assembly is inserted into the hollow cue shaft, the adapter of the adapter assembly is configured to receive an insertion pin of a cue handle and to hold the cue handle in position relative to the cue shaft.

A cue tip for a billiard cue is provided that includes multiple chemically bonded layers formed of a polyurethane material. Each layer is formed of a different polyurethane material with a different hardness than any adjacent layer. The defined layers include at least a proximal layer and a distal layer of polyurethane and at least one intermediary layer. Additional aspects presented include a leather-infused polyurethane layer and a compressed leather layer.
