The Soft Rubber Mullen Mouth Pelham bit has a mouthpiece that is a straight bar of rubber, without any joints or
ports. In the mullen mouth, the bar has a slight bow to it, curving
gently to allow some room for the tongue. It is gentle enough for a beginner rider.The rubber covered mouthpiece is softer and provides an alternative taste to steel or copper. Comes in a 5" mouthpiece with 4 1/4" cheeks.
**Action: The mullen mouth and straight bar are fairly similar
in action, placing pressure on the tongue, lips, and bars. The mullen
provides extra space for the tongue, instead of constantly pushing into
it, resulting in more tongue relief, and making it more comfortable,
but the mullen does not have as high of a port as a curb, thus does not
offer full tongue relief. This bit is generally considered a very mild
mouthpiece, although this varies according to the type of bit leverage
(snaffle, pelham or curb), and improper use may make it harsh, since
the majority of the bit pressure will be applied on the sensitive
tongue.
