This bit features a beautiful copper medallion welded into each no-pinch ball hinge mouth connection. The 3-piece ergonomic mouthpiece results in soft, even pressure across the tongue, bars and lips. The combination of the sweet and sour mouthpiece, increases salivation to lead to a more relaxed jaw and supple mouth and the copper roller acts as a pacifier. Are You Riding with Both Hands?
