The R11 Irons feature an ultra-thin face construction which promotes faster ball speed and distance in middle and long irons. The thinner clubface also results in an increased COR (Coefficient of Restitution, which has become a commonplace term amongst golfers when manufacturers began thinning out clubfaces to create a trampoline effect when the ball makes contact resulting in greater distance) assist in greater distances and control. Ping G20 Irons the R11's short irons have a shallow undercut channel between the face and rear to control feel and CG location, the mid-irons have a moderate undercut, and the long irons have a progressively larger undercut that pulls weight farther back from the face for added forgiveness.

This assures each R11 iron in the set is of uniform swingweight while also ensuring that the center of gravity location is precisely and optimally positioned in the center of the face between the toe and heel, also known as the “sweet spot.” The result is optimal consistency in feel and performance from one club to the next.
