Jump'In Small Check Round Leather Pelham BitImportant note for our customers: Leather bits are not guaranteed against bites, even from the very first use. Effect: The Pelham is a good compromise between the bridle and the snaffle. It provides varying degrees of leverage depending on the length of the shanks, the adjustment of the curb chain, and its setup. It induces poll flexion as well as pressure on the lower jaw. Jump'In leather covered bits are very soft and comfortable for the horse.
