Jump'in Twisted Short Shank Pelham BitWe love this bit for the high quality materials that are meant to last. Featuring 45 mm long shanks and standard 17 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 length, the curb chain adjustment and how it is assembled. The twisted thin cannons give more action to this bit
