French mouth bit thin cannons high port

 loose ring bits are the simplest in terms of action from the rider but also in the horse's mouth. The large rings give a slight lever action and most of all, a better direction. The high port prevents the tongue from going above the bit. This bit can suit horses that don't stay fixed during work and continually want to place their tongue above the bit. The movement of the bit around the one possible axis accentuates its effect.
