In one embodiment, the rib includes a web portion extending from an internal surface of the club head body and a flange portion coupled to a top surface of the web portion. The inclusion of the flange portion to the web portion increases the overall stiffness of the rib, thereby resulting in an increase in the natural vibration frequency of the club head so as to provide a more appealing sound and/or feel upon ball impact, thereby improving the overall sound characteristics of the club head. | 03-10-2016 |
