Continental 3 Ring French Link Dutch Gag Bit applies increased poll pressure when the reins are placed on the lower rings. The French Link eliminates the nutcracker and palate action of a single jointed bit and instead applies pressure to the horses tongue. Some horses with low palates may find this bit more comfortable as the mouthpiece should not come into contact with the palate when the bit is in action.
The three lower rings offer leverage options to increase the angle of the upper ring, controlling the amount of pressure being put on the poll and how much the bit is raised in the mouth.
