1. A shaft assembly comprising:
a shaft comprising an inner diameter and an outer diameter;
a grip;
an adhesive configured to permanently couple the shaft and the 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;
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;
wherein the adhesive extends between the shaft and the grip along a majority of the length of the internal bore;
wherein an amount of adhesive decreases from proximate the open first end to proximate the capped second end; and
the outer diameter including the adhesive remains constant across a portion of the shaft received by the internal bore.
