Golf club shafts and methods to manufacture golf club shafts

A golf club shaft comprising:

• a first tubular portion comprising a tip end portion and a distal end portion, the first tubular portion configured to attach to a golf club head;
• and
• a second tubular portion coupled to the distal end portion of the first tubular portion, the second tubular portion formed from a plurality of materials, each material of the plurality of materials being different from a material of the first tubular portion, the second tubular portion comprising:
• a butt end portion located distal from the distal end portion of the first tubular portion, the butt end portion comprising an outer diameter that is constant over a length of the butt end portion;
• an intermediate portion extending from the butt end portion toward the first tubular portion, the intermediate portion comprising an outer diameter that tapers over a length of the intermediate portion in a direction toward the first tubular portion;
• a neck portion extending from the intermediate portion toward the first tubular portion, the neck portion comprising an outer diameter that tapers over a length of the neck portion in a direction toward the first tubular portion;
• and
• an insert portion extending from the neck portion toward the first tubular portion, the insert portion comprising an outer diameter that is constant over a length of the insert portion, the insert portion received inside the first tubular portion via the distal end portion,
• wherein an outer diameter taper rate of the intermediate portion is different from an outer diameter taper rate of the neck portion.

A golf club shaft comprising:

• a first tubular portion comprising a tip end portion and a distal end portion;
• and
• a second tubular portion coupled to the distal end portion of the first tubular portion, the second tubular portion comprising a plurality of materials and defined by:
• a first length comprising a first uniform outer diameter;
• a second length comprising a variable outer diameter;
• and
• a third length comprising a second uniform outer diameter different from the first uniform outer diameter, the third length defining a portion of the second tubular portion that is received inside the first tubular portion via the distal end portion,
• wherein the second length is located between the first length and the third length, and
• wherein a total length of the second tubular portion is greater than a total length of the first tubular portion.
