Trust Sweet Iron Pelham Locked 16mm
The Pelham is a cheekpiece with combined leverage on the poll, just behind the ears, and the chin. It can be used with one or two reins, but if you choose to ride with one rein, this must be done with a connection between the big and the lower loose ring. The strap used for this is called a Pelham strap. The greater the leverage effect, the bigger the impact. This bit comes with a curb chain, which should be well-fitted.
The Locked mouthpiece is single-jointed, but locks when it is hinged. So when there is counter-pressure, it works like an unjointed mouthpiece. This makes the effect stronger. The bit changes back into a single-joint mouthpiece when there is less counter-pressure on the reins. This makes it an ideal corrective mouthpiece for horses that, for example, push against the hand and/or walk through the hand.
