Abstract

A golf club incorporating an interchangeable shaft system includes a shaft, a shaft sleeve, a club head. The shaft sleeve is coupled to an end of the shaft and is received in a hosel included in the club head. The shaft sleeve is removably coupled to the club head. Hosel and shaft sleeve alignment features provide discreet orientations between the shaft and club head.
