Jump'in Pelham Bit with RollersWe love this bit because the mouthpiece helps encourage even the fussiest of horses to relax. The short shank pelham design adds a small amount of leverage without being too harsh. Featuring 45 mm long shanks and standard 22 mm thick mouthpiece made of German Silver (65% copper, 23% zinc, 12% nickel). The Pelham bit is a great compromise between the bridle and the double bridle. It offers a lever action more or less strong depending on the cheeks
