Tapered grip and method of installing a tapered grip

A golf club shaft assembly comprising:

• a shaft comprising an inner diameter and an outer diameter;
• a tape layer configured to permanently couple to at least a portion of the shaft and a grip;
• the grip comprising:
• a tubular body including an internal bore extending from an open first end to a capped second end, and a body outer diameter which tapers at a constant rate from the first open end to the capped second end;
• the internal bore defining a length measured from the open first end to the capped second end and a diameter;
• wherein:
• the open first end comprises an internal tapered edge having a greatest diameter at an exterior of the open first end and tapers at an angle between 0.5 degrees and 5 degrees for a distance of up to 0.5 inches towards an interior of the internal bore, and wherein the greatest diameter is spaced from the body outer diameter at the first open end;
• the grip is configured to cover the tape layer, coupling the grip to the shaft;
• wherein the diameter of the internal bore varies linearly along the internal tapered edge;
• wherein the diameter of the internal bore is constant across a remaining portion of the length of the internal bore;
• wherein the tubular body comprises a single layer comprising a synthetic rubber material;
• and
• wherein the tape layer extends between the shaft and the grip along a majority of the length of the internal bore;
• wherein the tape layer comprises multiple wrapped layers that increase in number from proximate the capped second end to proximate the open first end;
• and
• the outer diameter including the tape layer remains constant across the portion of the shaft revied by the internal bore.
