Some riders, not adept at handling two sets of reins, prefer to use rein connectors, leather loops which connect from one ring to the other on the bit shank. The rein is then attached to this rounding.
The Pelham 55 has the shortest shank (55 mm) out of our range, this will soften poll pressure and leverage on the mouthpiece and curb.
The Segundo alleviates tongue pressure while keeping an even pressure on the bars of the mouth, encouraging the horse to stay light to the contact. Horses find it difficult to lean on this mouthpiece or put their tongue over the bit.
