A pelham is a type of horse bit that combines the actions of a snaffle and a curb bit into a single mouthpiece. It is fitted with two sets of rings — one at the mouthpiece and one at the end of a shank — allowing either two separate reins or a rounding leather (also called a pelham converter) to be used. The pelham acts on the corners of the mouth, the bars, the tongue, and through a curb chain, on the chin groove.
How the Pelham Works
The pelham’s action depends on which rein is used and with how much pressure. The top rein (attached to the snaffle ring at the mouthpiece) produces a more direct, lifting action similar to a snaffle. The bottom rein (attached to the shank ring) engages the shank and curb chain, creating a nutcracker-like downward pressure on the poll combined with chin groove pressure — characteristic of a curb bit.
A skilled rider uses the two reins independently: the top rein for normal steering and contact, and the lower rein for collection, downward transitions, or asking for flexion at the poll. Used correctly, the pelham is a refined and sympathetic bit. Used clumsily with equal pressure on both reins, or with a heavy hand, it creates confusion and discomfort for the horse.
The curb chain must be correctly fitted — it should lie flat in the chin groove and come into contact when the shanks reach approximately 45 degrees of rotation. A chain that is too loose allows the bit to rotate too far before engaging, creating a sudden jerk rather than a gradual signal. Too tight, and the horse is constantly under curb pressure regardless of rein contact.
Pelham Mouthpiece Variations
Pelhams are available in a wide range of mouthpiece shapes, each altering the action and severity of the bit. Common options include:
Straight bar: Even pressure across the tongue and bars. Simple and generally mild when the mouth is closed.
Port: A raised central section that creates space for the tongue and concentrates pressure on the bars. Higher ports increase severity.
Mullen mouth: A slightly curved mouthpiece that distributes pressure more evenly across the tongue. Often considered one of the more comfortable options and popular for horses that dislike tongue pressure.
Jointed: A jointed pelham creates a nutcracker action through the snaffle ring as well as curb action, making it more complex and potentially less predictable. Often associated with a harsher overall feel.
Shank Length and Leverage
Shank length directly affects severity. A longer shank creates more leverage from a smaller rein movement, amplifying the curb and poll action. Short-shanked pelhams are gentler and more suitable for horses new to curb action. Long-shanked versions are more common in showing and require a correspondingly light and experienced hand.
When a Pelham Is Used
Pelhams are popular in showing, hunting, polo, and some showjumping contexts. They are particularly common with heavier breeds or horses that are strong in a snaffle but not ready for a full double bridle. They offer the approximate effect of a double bridle in a single mouthpiece, making them practical where a double is not permitted or appropriate.
In showing, native breeds are frequently exhibited in a pelham with a rounding, giving the handler a single rein while still accessing both snaffle and curb action. The British Horse Society provides guidance on appropriate bit use across different disciplines and levels.
Fitting a Pelham
The bit should sit comfortably in the horse’s mouth at the correct height — just wrinkling the corner of the lips for a standard fit, or slightly higher depending on the mouthpiece type. The curb chain should be twisted clockwise until flat, then hooked at the appropriate link to give the correct tightness. Lip straps are recommended to keep the curb chain in place and prevent it from riding up.
Frequently Asked Questions
Is a pelham suitable for a novice rider?
A pelham in inexperienced hands carries a real risk of causing discomfort or confusion. The leverage and curb action it creates should only be used by riders with an established independent seat and soft, consistent hands. For novice riders or those still developing their feel, a well-fitted snaffle is a far better choice. If a horse genuinely needs more control, the problem is better addressed through training and fitness rather than escalating bit severity.
What is a pelham converter or rounding?
A pelham converter (rounding) is a short leather loop that connects the snaffle ring and the shank ring on each side of the bit, allowing a single rein to be used rather than two. It engages both actions simultaneously in a fixed ratio and limits the rider’s ability to use the two rings independently. Widely used in showing and for riders who prefer or require one rein, it is less precise than two separate reins but entirely acceptable in many disciplines.
How does a pelham differ from a kimblewick?
Both are single-mouthpiece bits with curb chain action, but a kimblewick has a different ring configuration and typically a D-ring shape with slots that allow some degree of rein position choice. The pelham has a dedicated shank and a clear distinction between its two rings. A kimblewick generally produces a milder and less variable curb action than a full pelham with a long shank, making it a common choice for children’s ponies and general hacking.
