Abstract
Embodiments of golf club heads having adjustable weighting systems with a plurality of discrete attachment locations capable of receiving one or more weights are described herein. The golf club heads described herein provide user adjustability of club head center of gravity to adjust ball flight while maintaining a high moment of inertia and low and back center of gravity position.
Claims20
A golf club head comprising:
- a club head body having a toe end, a heel end located opposite the toe end, a crown, a sole located opposite the crown, a strike face, and a perimeter positioned at a junction between the crown and the sole extending from near the heel end to near the toe end;
- and
- an adjustable weighting system positioned on the sole, the perimeter, or a combination thereof, the adjustable weighting system including:
- a plurality of discrete attachment locations;
- and
- one or more weights, each having a weight center of gravity, wherein each weight is configured to be coupled to one of the plurality of discrete attachment locations, and each weight is configured to be moveable between the plurality of discrete attachment locations to shift a center of gravity of the club head;
- wherein:
- the one or more weights are positioned such that the weight center of gravity of each weight is positioned within 0.50 inch of the perimeter of the club head when the weight is coupled to at least one of the discrete attachment locations;
- the one or more weights are positioned such that the weight center of gravity of each weight protrudes from an external contour of the sole, or is inset from the external contour of the sole by a distance less than 0.125 inch;
- and
- a combined moment of inertia of the club head about the club head center of gravity, defined as the sum of a crown-to-sole moment of inertia and a heel-to-toe moment of inertia, is greater than 8,000 g·cm2.
