Leather Pelham roundings are used to convert the Pelham or double rein bridle to a single rein.
One strap attaches to the snaffle bit and the other strap attaches to the curb, or weymouth bit. The rider then only needs to hold one pair of reins, making this a popular choice for young riders where the stronger action of a pelham bit is required.
Because the rein doesn’t attach directly to the curb bit, the normal curb action of the pelham is reduced greatly.
