Jointed

Jointed Pelhams are a common variety in this family of bits, though they are a mixed bag in terms of advantages and disadvantages. Just like a jointed snaffle, the mouthpiece has two arms that are linked together in the center, allowing them to move independently from each other, thus affording more lateral control. When used on the snaffle ring, this action is basically the same as a full-cheek jointed snaffle. However, when used with a curb rein, the nutcracker effect of the jointed mouthpiece, which happens to a lesser extent with a snaffle, is magnified by the leverage of the curb shanks. This can lead to severe squeezing of the tongue and cheeks, as well as possibly pushing upwards on the palate, potentially causing the horse to open its mouth against the bit.

Of all the Pelham bits, this one is perhaps most at the extremes, having the greatest comfort and flexibility on the snaffle setting, and potentially the greatest discomfort on the curb setting. This makes it most ideal for situations where the horse is primarily ridden on the snaffle rein, but may need the occasional curb action to maintain control.
