This mullen mouth bit with D-ring side pieces made of hard carbon allows direct transmission of the rein aid to the horse's tongue and lower jaw thanks to the fixed side pieces. The smooth surface of the material ensures a pleasant feel, while the fixed side pieces also protect the sensitive corners of the mouth. The bit lies particularly calmly in the mouth and, thanks to the lateral limitation of the D-rings, offers valuable support when riding turns – especially for horses that tend to break out over the shoulder.

The mullen mouth acts evenly on the entire surface of the tongue and the lower jaw. The continuous bar without a joint ensures that the pressure distribution remains constant and even, making it particularly suitable for horses with sensitive mouths or for riders who are looking for a calm and even contact. The D-shape of the side pieces frames the horse's mouth and provides additional guidance without exerting too much pressure.
