Perfect fit? No problem! The bits of the ""Dynamic RS"" series are ergonomically shaped: Their joints are always tilted forward by 45°. This way they allow for an even distribution of pressure. Because all Dynamic RS bits fit anatomically correctly between the tongue and the palatal arch, they are mouth-friendly, allow effective aiding and are also suitable for horses with a small mouth. The fixed sides of this bit allow the bit to be applied directly to the horse's tongue and lower jaw. They also protect the sensitive corners of the mouth and frame the horse slightly at the sides. The bit lies very quiet in the mouth.
