Golf club heads with ribs and related methods
Provided herein are embodiments of golf club heads comprising a crown and a ribbed region. The ribbed region of the golf club head can be positioned on a portion of the crown and can further include a ribbed wall, wherein the ribbed wall comprises a ribbed wall interior surface, a ribbed wall exterior surface, and one or more external ribs. The one or more external ribs can protrude from the ribbed region to increase the strength of the crown and beneficially reduce crown thickness. Other embodiments and related methods are disclosed herein.
