Abstract:
1. A golf club comprising: a shaft; a body comprising a hosel having an upper bearing surface and a hosel bore defining a hosel bore axis; an adjustable sleeve comprising a plurality of engaging surfaces that engage with the body to restrict rotation of the sleeve relative to the body such that the sleeve is configured to be secured within the hosel bore in a plurality of discrete rotational positions relative to the hosel bore axis, the sleeve further comprising a shaft bore defining a shaft bore axis that forms a sleeve angle of at least 1.5° with the hosel bore axis when the sleeve is secured within the hosel bore, the shaft bore being secured to a distal end portion of the shaft such that the shaft extends along the shaft bore axis; and a retainer configured to releasably secure a distal end portion of the sleeve to the body in one of the rotational positions; an adjustable sole piece that can be secured to a sole of the club head at six or more different discrete rotational and axial positions with respect to an axis extending through sole piece, wherein the face angle of the club head is different at each position of the sole piece; wherein the sole piece comprises an outer wall that includes a plurality of notches that are configured to engage with corresponding ridges on the sole of the club head body to prevent the sole piece from rotating when the sole piece is secured to the sole; wherein the square loft angle of the golf club head can be adjusted to a plurality of different values by changing the rotational position of the sleeve within the hosel bore; and wherein, when the sleeve is secured to the body via the retainer in one of the rotational positions, an intermediate portion of the sleeve extending axially from a lower shoulder of the sleeve to a distal end of a uniform diameter portion of the shaft bore is under a tension that is constant along the axial length of the intermediate portion of the sleeve.
