Some embodiments of the lightweight golf clubs described herein include a thin crown, a thin sole, a mass efficient weight system, and a thin faceplate to maximize performance gains (e.g., ball travel distance, impact efficiency, and ball speed) targeted to individuals with swing speeds less than 85 mph. As will be further described below, in order to achieve a lightweight golf club head (having a thin crown, a thin sole, a mass efficient weight system, and a thin faceplate), the golf club head further comprises a crown-to-faceplate bridge and a sole-to-faceplate bridge to control the characteristic time (CT) properties of the golf club head.
