Korsteel Sweet Iron Loose Ring French Link Snaffle. The Loose Ring French Link is a double jointed bit that acts on the tongue and the bars of the mouth. The French Link eliminates the nutcracker and palete action of a single jointed bit and instead applies pressure to the horse's tongue. The Loose Ring is ideal for horses with a tendency to lean on the rein; the loose rings of the bit provide more movement than a fixed cheek bit and allow the rider to move the bit more in the horse's mouth preventing the horse from leaning and grabbing hold of the bit as easily.
