An inner steel cable runs through the mouthpiece, which is then covered in soft plastic and covered with non-toxic silicon for maximum comfort. This bit is often suitable for horses that struggle to accept a conventional metal bit, and those with light or sensitive mouths that can nevertheless become strong and need a little extra control. The soft, elastic nature of the mouthpiece dissuades the horse from pulling and fighting the contact, as it is so gentle there is little for the horse to object to.
The rings on the Pelham provide a similar action to that offered by a double bridle, but in a less precise manner. When the top rein is used, the bit has a similar action to that of a hanging cheek snaffle, putting pressure on the bars of the mouth as well as a limited amount of poll pressure. The curb rein provides leverage action on the poll and also puts pressure on the curb groove via the curb chain.
The pelham is delivered with short and long sides. A bit with short sides is called baby pelham. A pelham with long sides is a normal pelham. This bit can be used with one or two reins. You can also use a pelham strap, this connects the bit ring with the ring a the bottom of the sides. A pelham strap connects the two reins, so just one rein is needed. The effect is a bit softer than riding with two reins.
The pelham is used in combination with a curb chain. The pelham is often used with strong horses. Because of the leverage effect created by the sides, the bit is pretty sharp. By using this bit it s easier to ride a horse rounder in the neck. The longer the sides, the sharper it is. The pelham is not suitable for inexperienced riders or horses.
