The loose rings provide gentle contact to the mouth. They allow to have a slight indirect contact compared to fixed rings, which makes it easier to play in the fingers and limit the taking of excessive tension. 

The Harcour brand double-jointed loose ring bite is a double-broken bite that offers simple contact. It allows a better relaxation of the mouth of your horse by a transmission of your aids more smoothly. Unlike the simple break bite that acts on the palate, the double break bite acts on the tongue without causing pain. It is important to know that the horse’s palate is a sensitive place not to be neglected.
