Abstract
A golf club head (42) having more than 50% of a volume forward of a center of gravity and more than 50% of a mass rearward of the center of gravity is disclosed herein. The golf club head (42) preferably has a volume ranging from 420 cubic centimeters to 470 cubic centimeters. The golf club head (42) preferably has a moment of inertia about the Izz axis through the center of gravity of the golf club head greater than 4000 grams-centimeters squared, and a moment of inertia about the Ixx axis through the center of gravity of the golf club head greater than 3000 grams-centimeters squared.
Claims20
A golf club head comprising:
- a body having a face wall, a crown wall, a sole wall, a heel wall, a rear wall, and a toe wall;
- wherein the golf club head has a volume ranging from 350 cubic centimeters to 500 cubic centimeters and a mass ranging from 190 grams to 250 grams;
- wherein more than 50% of the volume of the golf club head is forward of the center of gravity of the golf club head and less than 50% of the mass of the golf club head is forward of the center of gravity, wherein forward of the center of gravity is toward the face wall.
A golf club head comprising:
- a face component composed of a first material, the face component comprising a striking plate portion and a return portion;
- and
- an aft-body coupled to the return portion of the face component, the aft-body composed of a second material having a density less than that of the first material, the aft-body comprising a crown portion, a sole portion, the sole portion having a bottom section and a ribbon section, the ribbon section being located between the crown portion and the bottom section of the sole portion;
- wherein the golf club head has a volume ranging from 350 cubic centimeters to 500 cubic centimeters and a mass ranging from 190 grams to 250 grams;
- wherein more than 50% of the volume of the golf club head is forward of the center of gravity of the golf club head and less than 50% of the mass of the golf club head is forward of the center of gravity, wherein forward of the center of gravity is toward the striking plate portion.
