A golf club comprising: a grip portion including a grip cover and grip shaft; a lower shaft connected with the grip portion; a club head connected with a lower portion of the lower shaft; a first axial direction being co-axial with the lower shaft and extending toward the club head; a second axial direction opposite the first axial direction; an engaging mechanism located within the grip portion and connected with a top collar; a rotational shaft connected with the engaging mechanism and being configured to rotate upon movement by the engaging mechanism; a locking mechanism connected with the rotational shaft, the locking mechanism including a locking insert and a locking collar located on the locking insert, the locking insert being configured to retain the locking collar during axial movement; and the lower shaft having an inner surface that is in frictional contact with the locking collar, wherein the locking insert is movably engaged with the locking collar and a rotational movement by the rotational shaft in a first rotational direction causes the locking collar to move in the second axial direction to create a frictional locking engagement between the locking collar and the inner surface of the lower shaft, wherein the locking collar has at least two finger portions that engage an engaging surface of the locking insert to prevent movement with respect to the lower shaft.
