Abstract: A golf club or part thereof may include a ball-strike head 1, a hosel 2 having a shank 5 that extends along at least part of, and that engages with, the head, biasing means (eg a spring 9) that provides a locking force that seeks to move the head 1 and hosel apart 2 and, in doing so, causes the head to remain locked in one or other of a selection of loft settings 4. The club or part thereof being such that hand force can be applied to move the head 1 inwards to overcome the locking force to free the head to be turned into another of the loft settings 4. The arrangement is such that subsequent reverse movement of the head will cause it to be locked in that other setting.
