A Pelham is a type of bit that features shanks and a curb chain, which apply pressure behind the ears, creating leverage. The length of the shanks and the chin strap or curb chain determine the severity of the bit. A short-shanked Pelham is sometimes referred to as a Baby Pelham, while a long-shanked Pelham is more commonly used. When used with two reins, the top ring provides a softer grip, while the bottom ring offers Pelham leverage. Alternatively, a connecting strap (bridge) can be used with a single rein.
The Pelham bit is commonly used with stronger horses as it allows for deeper flexion, but it is not suitable for inexperienced riders or horses due to the potential for strong effects. It is important to note that the use of a Pelham requires proper technique and education on the part of the rider. Pelhams should only be used with experienced hands and with careful consideration given to the horse's comfort and safety.
