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.

A golf club head comprising:
- a primary component comprising:
- a strike face having a front surface;
- and
- a rear surface behind the front surface;
- and
- a secondary component pivotally associated with the rear surface of the primary component, the secondary component adjustable between a first orientation and a second orientation relative to the primary component, wherein 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.
