Pelham Max Control double jointed lock up

The max control bit is an educational bit, a classic double bit in appearance. However, when the horse opposes the rider's hand, the bit locks (self-locking effect) at the breaks. This bit can be used to correct the horse if he doesn't listen to the rider. It's soft and hard at the same time. If the horse is listening to his rider, the bit will have the action of a classic pelham double break, whereas if he is against his rider, the bit becomes hard through its self-locking effect.
