Abstract
A golf club comprises a shaft, a club head, and a connection assembly that allows the shaft to be easily disconnected from the club head. In particular embodiments, a sleeve including a top portion, a middle portion connected to the top portion is described. The middle portion includes a thin wall thickness. A bottom portion is connected to the middle portion including a plurality of engaging surfaces. A central longitudinal axis and an offset angle offset from the central longitudinal axis is described. The offset angle allows a maximum loft change of about 0.5 degrees to about 4.0 degrees. The total weight of the sleeve is less than 9 g.
Claims21
A golf club head comprising:
- a body comprising a face plate, a crown, a hosel, and a sole;
- an adjustable head-shaft connection system configured to allow the golf club head to be adjustably attachable to a golf club shaft in a plurality of different positions resulting in different combinations of loft angle, face angle, and lie angle;
- and
- at least two weights attachable to and removable from the body at a plurality of different positions relative to the body;
- wherein at least a portion of the crown has an areal weight of less than about 0.36 g/cm2.
A golf club head comprising:
- a body comprising a striking face and a hosel;
- an adjustable head-shaft connection system configured to allow the golf club head to be adjustably attachable to a golf club shaft in a plurality of different positions wherein a longitudinal center axis of the hosel is offset from a longitudinal center axis of the shaft;
- and
- at least two weights attachable to and removable from the body at a plurality of different positions relative to the body;
- wherein the center of gravity of the golf club head has a Z-axis coordinate of less than or equal to about 0 mm.
A golf club head comprising:
- a body comprising a striking face and a hosel;
- an adjustable head-shaft connection system configured to allow the golf club head to be adjustably attachable to a golf club shaft in a plurality of different positions resulting in different combinations of loft angle, face angle, and lie angle;
- and
- at least two weights attachable to and removable from the body at a plurality of different positions relative to the body;
- wherein a golf club head moment of inertia about the head center of gravity X-axis is between 200 kg·mm2 and 500 kg·mm2.
A golf club head comprising:
- a body comprising a striking face and a hosel;
- an adjustable head-shaft connection system configured to allow the golf club head to be adjustably attachable to a golf club shaft in a plurality of different positions wherein a longitudinal center axis of the hosel is offset from a longitudinal center axis of the shaft;
- and
- at least two weights attachable to and removable from the body at a plurality of different positions relative to the body;
- wherein a golf club head moment of inertia about the head center of gravity Z-axis is between 400 kg·mm2 and 500 kg·mm2.
A golf club head comprising:
- a body comprising a striking face and a hosel;
- an adjustable head-shaft connection system configured to allow the golf club head to be adjustably attachable to a golf club shaft in a plurality of different positions resulting in different combinations of loft angle, face angle, and lie angle;
- and
- at least two weights attachable to and removable from the body at a plurality of different positions relative to the body;
- wherein the volumetric displacement of the golf club head is greater than 400 cm3.
