  • GOLF CLUB GRIP WITH REMINDER RIB
    Publication number: 20230191212
    Abstract: A golf club grip with reminder rib is provide that has a hollow main body having an inner diameter configured to fit to a shaft, wherein the hollow main body comprises a protruding feature that extends along a length of the hollow main body. The protruding feature protrudes from an outer surface of the hollow main body without requiring the shaft to be inserted in the hollow main body. By not requiring the golf grip to be on the shaft in order to cause a protrusion above the outer surface of the main body, the reminder rib formed by the protruding feature can be ensured to be about 0.
