The Dee ring compromises between an eggbutt and a full cheek snaffle, preventing pinching at the corners of the mouth and the dangers posed by the arms of a full cheek . The slow twist mouthpiece creates pressure points on the bars making a stronger bit.
The gag action of this bit provides leverage and poll pressure to the horse. Thicker mouthpiece is softer on the corners and the bars of the mouth and pressure created by the reins is spread over a larger surface area.
The French link in this bit means pressure is applied to both sides of the tongue. Horses with low palates may find this bit more comfortable as the mouthpiece should not contact the palate when the bit is in action.
