Jump'In Full cheek Swales bitComposition: German Silver (65% copper, 23% zinc, 12% nickel), a relaxing and solid alloy. Effect: the Swales bit has some similarities with the Pelham bit, but the horse doesn't feel any pressure on the neck because there is no action on the bridle cheek pieces. It is the only bit with a lever action that doesn't put any pressure on the horse's neck. It is used with a single pair of reins and a curb chain, and it is less restricting than a Pelham bit
