Abstract: A system for fitting golf clubs to golfers that enables an overall club length to be varied without varying the length of the golf club shaft. The system enables a greater number of combinations of club characteristics, such as shaft flex, brand, and length, to be contained within a club fitting cart and/or for a same number of combinations of club characteristics to be contained within a smaller cart.

Abstract: A golf club head includes a primary component and a secondary component, wherein the secondary component is rotatably or pivotally associated with the rear surface of the primary component. The secondary component is adjustable between a first orientation and a second orientation relative to the primary component such that the golf club head has a first sole contour when the secondary component is in the first orientation and a second sole contour when the secondary component is in the second orientation, the first sole contour being different from the second sole contour.
