3 Ring French Link Gag should be worn with 2 reins preferably; the first rein should be used on the snaffle ring, which is the first ring adjacent to the mouthpiece. When the first rein is attached to the snaffle rein it is used just like a loose ring hanging cheek bit, which uses poll pressure and lip pressure due to the sliding loose ring also applies various pressures in the mouth depending on the mouthpiece it is in conjunction with. When the second rein is attached to the ring below, the pressures are increased as the lower rings produce more leverage. In the instance of using 2 reins then this bit can be used as a hanging cheek bit and then when more help is required, the second rein can be brought into play. If the bit is only used with one rein on the lower ring, then the pressure in applied constantly and no pressure release is available for the horse. The gag produces a head raising action and is often used for cross country and/or jumping where the head needs to be raised quickly in order to gain control and so to get ready for the next jump. The French link has proven one of the most popular mouthpieces; it has 2 joints, which means the pressure of the bit is distributed over both the tongue and bars of the mouth. Because the mouthpiece has two joints, it shouldn’t cause any interference with the roof of the mouth. The French link uses tongue pressure to encourage the horse to go on the bit and has bar and lip pressure but not a squeezing action like that of a bit with a single joint. The more joints a bit has the less likely the horse is to lean as the bit becomes more mobile.
