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.

1. A golf club head comprising: a body comprising a striking face, a crown, a sole, and a hosel, with the hosel defining a hosel opening, an annular shoulder, and an upper bearing surface, and the sole defining an opening that is in communication with the hosel opening and an internal bearing surface;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, with the adjustable head-shaft connection system having a sleeve with an upper portion engaging the upper bearing surface of the hosel and a threaded lower opening, and a screw extending through the opening in the sole and having a head defining a bearing surface engaging the internal bearing surface of the body and a threaded region engaging the threaded lower opening of the sleeve; anda hosel insert secured inside the hosel and contacting the annular shoulder, the hosel insert of a height dimension less than a height dimension of the hosel including a rotation prevention portion configured to mate with a rotation prevention portion of the adjustable head-shaft connection system;wherein the center of gravity of the golf club head has a Z-axis coordinate of less than or equal to about 0 mm. 2. The golf club head of claim 1, wherein the center of gravity of the golf club head has a Z-axis coordinate of less than or equal to about −1 mm. 3. The golf club head of claim 1, wherein the center of gravity of the golf club head has a Z-axis coordinate of less than or equal to about −2 mm. 4. The golf club head of claim 1, further comprising at least two weights attachable to and removable from the body at a plurality of different positions relative to the body. 5. A golf club head comprising: a body comprising a striking face, a crown, a sole, and a hosel, with the hosel defining a hosel opening, an annular shoulder, and an upper bearing surface, and the sole defining an opening that is in communication with the hosel opening and an internal bearing surface;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, with the adjustable head-shaft connection system having a sleeve with an upper portion engaging the upper bearing surface of the hosel and a threaded lower opening, and a screw extending through the opening in the sole and having a head defining a bearing surface engaging the internal bearing surface of the body and a threaded region engaging the threaded lower opening of the sleeve; anda hosel insert secured inside the hosel and contacting the annular shoulder, the hosel insert of a height dimension less than a height dimension of the hosel including a rotation prevention portion configured to mate with a rotation prevention portion of the adjustable head-shaft connection system;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. 6. The golf club head of claim 5, wherein the golf club head moment of inertia about a head center of gravity X-axis is between 200 kg·mm2 and 300 kg·mm2. 7. The golf club head of claim 5, further comprising at least two weights attachable to and removable from the body at a plurality of different positions relative to the body. 8. A golf club head comprising: a body comprising a striking face, a crown, a sole, and a hosel, with the hosel defining a hosel opening, an annular shoulder, and an upper bearing surface, and the sole defining an opening that is in communication with the hosel opening and an internal bearing surface;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, with the adjustable head-shaft connection system having a sleeve with an upper portion engaging the upper bearing surface of the hosel and a threaded lower opening, and a screw extending through the opening in the sole and having a head defining a bearing surface engaging the internal bearing surface of the body and a threaded region engaging the threaded lower opening of the sleeve; anda hosel insert secured inside the hosel and contacting the annular shoulder, the hosel insert of a height dimension less than a height dimension of the hosel including a rotation prevention portion configured to mate with a rotation prevention portion of the adjustable head-shaft connection system;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. 9. The golf club head of claim 8, wherein the golf club head moment of inertia about a head center of gravity Z-axis is between 420 kg·mm2 and 450 kg·mm2. 10. The golf club head of claim 8, further comprising at least two weights attachable to and removable from the body at a plurality of different positions relative to the body. 11. A golf club head comprising: a body comprising a striking face, a crown, a sole, and a hosel, with the hosel defining a hosel opening, an annular shoulder, and an upper bearing surface, and the sole defining an opening that is in communication with the hosel opening and an internal bearing surface;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, with the adjustable head-shaft connection system having a sleeve with an upper portion engaging the upper bearing surface of the hosel and a threaded lower opening, and a screw extending through the opening in the sole and having a head defining a bearing surface engaging the internal bearing surface of the body and a threaded region engaging the threaded lower opening of the sleeve; anda hosel insert secured inside the hosel and contacting the annular shoulder, the hosel insert of a height dimension less than a height dimension of the hosel including a rotation prevention portion configured to mate with a rotation prevention portion of the adjustable head-shaft connection system;wherein the volumetric displacement of the golf club head is greater than 400 cm3. 12.
