The original Red Rat grip covers are hand made using high quality, non-porous, autoclavable rubber. Their 1/4” thick walls creates a soft cushion between your hand and your grip, that also effectively absorbs vibration, creating less hand strain. Covers add 1/2” in size to your grip. Please order the same size Red Rat cover as the grip you will be using it on. Available in Original style and Tapered for more control. A great innovation available in three sizes 5/8″, 3/4″ and 1″. Black Only.
