The Korsteel Stainless Steel Cambridge Mouth Slotted Ring Kimblewick Bit is a fixed cheek bit that offers a stronger alternative to snaffle bits. The slotted rings give two options for rein positioning for different strength/leverage requirements. The Cambridge mouth piece is a non-jointed fixed mouthpiece with low port to allow room for the horses tongue and to reduce pressure on the horse's mouth. The Cambridge mouth Kimblewick bit offers similar benefits to the Pelham due to the curb action, but with the benefit of being able to be use with a single rein.
