4210456 Sprenger Rubber Pelham Single Jointed Stainless Steel 18mm

Rubber bits from Sprenger are made of soft but tough rubber that has a
Stainless steel cable inside to reinforce the mouthpiece. Rubber
generally has an “eraser-effect”. It is therefore important that horses
are salivating and chewing well when using these bits. If the horse does
not produce enough salivation the rubber bit will be uncomfortable.
Different from pure metal bits there is the danger of the rubber being
easily bitten through when the bit is not attached correctly and gets
into contact with the teeth.The Pelham is a bit that provides additional lever action on the poll.
Pressure is applied to the lower jaw bones by the use of a curb chain.
In a way the Pelham is a combination of a Weymouth and a bradoon.
Pelhams can be used with one or two reins, which enables different rein
options. Direct pressure is applied to the horses tongue and bars if
the rider only uses the snaffle rein.

If horses tend to toss the head it makes sense to attach a second rein
to the lower cheek piece ring to apply pressure on the horses poll. The
horse will try to dodge this pressure by lowering the head. The curb
chain should come into play at maximum angle of 45 (lower cheek to
horses mouth) to avoid the horse lowering its head too much.

It is very common to use a double rein as it enables the ability to
apply pressure on the horses poll if necessary. Pelhams are also widely
used with Pelham straps. This strap is attached to the upper and lower
cheek piece ring and the rein is fixed to this strap.
