The Cambridge Mouth Pelham is a Pelham with a medium height port. The port in this Pelham creates more space for the horses tongue reducing the needFor the Horseto fight the contact.
The Cambridge ported mouthpiece is an alternative to the straight bar for horses with a larger tongue. This mouthpiece is very useful for those horses that have a very soft mouth and don't like complicated mouthpieces, it may also be useful for horses that back off the contact and need that extra bit of confidence in the bit.
The Pelham is an incorporation of the Weymouth and Bradoon, and therefore designed to be used with two reins. The first rein is attached to the larger snaffle ring, and the second rein is attached to the ring at the bottom of the shank. When the first rein is used the Pelham acts like a hanging cheek snaffle, putting slight pressure on the poll and various pressures in the mouth depending on the mouthpiece. When the second rein is brought into play, this increases the leverage and lip pressure, and also the curb chain comes into play.
This bit can be used with double reins or with Pelham Roundings for novice riders.
