The 1307 Fine Line Flex Pelham`s mouthpiece is made from flexible, food-grade PU, offering a warmer feel in the mouth even at lower temperatures. A concealed metal core ensures break-resistance and security. The anatomically shaped mouthpiece follows the natural line of the horse’s mouth, lying evenly across the tongue and bars while a slight tongue relief reduces pressure. The Pelham design allows combined influence on the tongue, bars and poll, with the curb chain adding an additional level of control when engaged.
