Feeling Pelham Single Jointed - Rubber

Description of (baby) pelham:

The pelham is delivered with short and long shanks. A bit with short shanks is called a baby pelham. A pelham with long shanks is a normal pelham. This bit can be used with one or two reins.
You can also use a pelham strap, this connects the bit ring with the ring a the bottom of the shank. A pelham strap connects the two rings, so just one rein is needed. The effect is a bit softer than riding with two reins.
The pelham is used in combination with a curb chain.
The pelham is often used with strong horses. Because of the leverage effect created by the sides, the bit is pretty sharp. By using this bit it’s easier to ride a horse rounder in the neck. The longer the sides, the sharper it is.
The pelham is not suitable for inexperienced riders or horses.

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.

Single Jointed mouthpiece features:

A single jointed bit has a hinge point in the middle that puts pressure on the layers, lips and sides of the tongue. A single jointed bit squeezes the tongue slightly under pressure and puts less pressure on the tongue.
The hinge point 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.
