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.
