Description of baby pelham: A baby pelham is a bit with a curb chain and short shanks, which gives pressure behind the ears and creates leverage. A short-shanked pelham is also called baby pelham, and a long-shanked pelham is a common pelham. The length of the shanks and the chin strap or curb chain determine the strength of the impact. The longer the shanks, the sharper the effect. A pelham can be used with 2 reins; The one rein on the top ring for a soft grip and the other rein on the bottom ring for pelham leverage. You can also use one rein by means of a connecting strap (Bridge), to which the rein is attached. The use of a pelham makes it easier to set a horse deeply and is often used with stronger horses. The pelham is not suitable for inexperienced riders or horses, this bit can work quite strongly. Straight mouthpiece features: A straight mouthpiece consists of 1 piece and gives pressure on the tongue, layers and lips. The shape and thickness of the mouthpiece determine where the pressure will be in the mouth. A straight mouthpiece with a tongue port gives more pressure on the layers and keeps the tongue free. The straighter and thicker the mouthpiece, the more pressure on the tongue.
