Rubber

Rubber

Features rubber or plastic bit:

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 (Beris, Happy Mouth) is smoother and doesn’t have this problem.
