Abstract

The present invention relates to golf club heads having an optimized ball speed vs. CT relationship. A golf club head is disclosed that includes a body and a plurality of stiffening members and satisfies the equation V ballnorm ≥0.0356x+140.82. The body includes a face section, a bottom section, and a crown or turn section, and defines a hollow interior. Each of the plurality of stiffening members extends within the hollow interior from the crown or transition section to the sole section to reduce stress exerted on the face section during impact with a golf ball. The stiffening members are all positioned within 1 inch of the back surface of the face section as measured in a plane perpendicular to the center of the face, and are spaced apart from each other within the hollow interior by a distance of 0.500 to 2.00 inches.
