Metal AB Pelham Single jointed Rubber

Pelham:

A pelham is a bit with a curb chain and 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.

Single Jointed

A single jointed bit has a hinge point in the middle that puts pressure on the lips, layers and sides of the tongue. A single jointed bit squeezes the tongue slightly under pressure and puts less pressure on the tongue.
A single jointed bit rises slightly in the middle and can sting the palate. In this case is it better to choose a double-jointed or straight mouthpiece.
A single jointed bit is a good basic bit, suitable for many horses and riders.

Description rubber & plastic bits:

A rubber bit can be flexible, but also can contain a hard core. The flexible rubber bit has a steel wire running through is, so the bit can not break. The flexible bit is softer.
Black rubber has the disadvantage that if a horse has a drier mouth, the bit gets hot by friction and then can burn on the tongue. When a horse produces enough saliva, a rubber bit is the softer variant of a metal bit. The plastic variant is smoother and doesn’t have this problem.
