This stainless steel bit has a simple jointed mouthpiece. An American, who wished to move the ring-mouthpiece connection as far from the horse’s lips as possible, to reduce any chance of pinching, devised the D-ring. The D-ring has a similar action to that of an eggbutt cheek. As it is fixed to the mouthpiece, it creates a more stable feel for the horse. This often helps a fidgety mouthed horse to settle. Alternatively it can encourage a steadier head to start leaning. Most commonly used in racing, it can also be worn by showjumpers.
