All JP bit feature curved bars that prevent the bit from hitting the roof of the horse's mouth and eliminate the nutcracker-like action that can pinch the horse's tongue. Gently twisting bars encourage heavy-mouthed horses to soften. Curved mouthpiece encourages relaxation. 14mm dia. Sizes: 4 3/4", 5", 5 1/2", 6".
