The Pelham bit combines elements of both a snaffle and a curb bit into one mouthpiece. “Snaffle reins” attach to rings on the side of the mouthpiece, while “curb reins” attach to shanks designed to apply pressure to the poll and under the chin via a strap or chain. A pelham encourages the horse to bend at the poll, without the bulk and difficulty of two separate mouthpieces.
