Jointed Pelham Bit

A Pelham bit is a leverage bit designed to combine the actions of a snaffle and a curb (traditionally achieved separately by a double bridle) into a single mouthpiece, giving the rider both direct rein aids and additional leverage when needed.

Design

• The Pelham has a shank extending below the mouthpiece, with the mouthpiece ring at the top and a lower ring at the end of the shank.
• Two rein attachment points: The upper ring attaches to the cheekpiece of the bridle and also takes the snaffle rein, applying direct pressure similar to a plain snaffle. The lower ring is used for the curb rein (or a converter), engaging the shank's leverage action.
• It is used with a curb chain, which sits in the chin groove and engages when the curb rein is used.
• The mouthpiece can vary widely — mullen mouth, jointed, low-port, or even a "Rugby" style with a roller — depending on the desired feel and severity.
• Some riders use a "bit converter," "roundings," or a delta rein — connecting the two rings — allowing a single rein to be used instead of two, at the cost of losing the ability to apply snaffle and curb pressure independently.

Function

• Dual action, single mouthpiece: The snaffle rein (top ring) applies direct pressure on the bars and corners of the mouth. The curb rein (bottom ring) engages the shank, creating leverage that applies pressure simultaneously to the poll, the mouth, and the curb chain under the chin.
• Encourages rebalancing and softness: This combined action encourages the horse to rebalance, soften in the contact, and come down/forward to the bit, creating a framed, stable feeling.
• Adjustable severity via reins: A rider using two reins can blend between the milder snaffle action and the stronger curb/leverage action as needed, moment to moment — for instance, using mostly snaffle rein for steering and light contact, with occasional curb rein for half-halts or steadying.
• Leverage ratio depends on shank length: Longer shanks create more leverage and a stronger curb effect; shorter-shanked Pelhams are milder.
• With roundings/delta rein (single rein): Blends the two actions into a single, averaged pressure, sacrificing the fine control of separate reins for simplicity — often considered a "middle ground" bit, but less precise than using two reins properly.

What it's good for

• Horses that get strong or heavy in the hand: The Pelham can be useful for horses that become strong, lean on the rider's hand, or need extra help maintaining balance and control — particularly in jumping or faster work, where quick, effective half-halts matter.
• Riders skilled with two reins (or using a delta rein): Best suited to riders who can independently manage a snaffle rein and a curb rein, or who use a delta rein for a more unified but still leverage-assisted feel.
• Disciplines like hunting, showing, eventing, and polo: Popular in disciplines where extra control is wanted but a double bridle's complexity isn't practical or permitted.
• Horses that benefit from poll flexion cues: The curb action can encourage a horse to soften and flex at the poll, similar to (but milder than) a double bridle.
• As a stepping stone toward a double bridle: Some trainers use the Pelham to introduce a horse to the feel of curb pressure before progressing to a double bridle, since it combines both actions in one bit.

A note on severity, fit, and hand

• The Pelham is generally considered a stronger, more advanced bit than the fixed-cheek or loose-ring snaffles, and than the Kimberwick, due to its adjustable shank leverage and dual-rein capability.
• Pelham bits should always be used with a delta rein or two reins — never a single plain rein attached to just one ring — to ensure the bit functions and releases correctly.
• It should always be used with a soft, educated hand and a clear release when the horse responds, since the leverage action is only effective and comfortable when paired with good timing and feel.
• A properly fitted curb chain (with roughly 2 fingers' clearance) is essential for correct, comfortable action and to avoid pinching.
• Not recommended for green or inexperienced horses, or for riders still developing independent rein control, since incorrect or heavy curb rein use can create discomfort or confusion.

Competition legality

The Pelham is permitted in many disciplines — showing (including some show hunter and pony classes), eventing, showjumping, and polo — but like the Kimberwick, it is not permitted in FEI dressage competition, which restricts riders to a plain snaffle (or double bridle at advanced levels).

Summary

The Pelham is a leverage bit combining snaffle and curb actions in one mouthpiece, offering significant extra control through its shank and curb chain to help horses rebalance and soften — making it a popular choice for horses that get strong or heavy, especially in jumping and faster work, provided it's used with a delta rein or two reins and a soft, educated hand. It's generally considered more severe than snaffle-type bits, with no FEI dressage eligibility.

This combines the classic single-joint mouthpiece shape with a soft, flexible polymer material — offering the same simple, direct signal as a metal single joint, but with the comfort and acceptance benefits polymer is specifically known for.

Design

• The mouthpiece consists of two bars joined by a single center hinge — the same basic structure as any single-jointed snaffle, producing the classic "nutcracker" fold when rein pressure is applied.
• Made of "space age" polymer, often apple-scented, molded around an internal stainless steel core for strength, though the steel isn't in direct contact with the mouth.
• Unlike rubber, polymer tends to be firmer and more consistently shaped, holding its form well while still offering more give than plain metal.

Function

• Softened nutcracker effect: The underlying single-joint mechanics are unchanged — the two halves still fold upward at the center hinge under rein pressure, and the joint can still rise toward the palate. But because the mouthpiece is polymer rather than rigid metal, the sensation is considerably gentler, even though the fold itself is identical to a metal version.
• Warm, consistent contact: Polymer maintains a more neutral temperature than metal, avoiding the "cold bit" sensation, and offers a smooth, non-abrasive surface against the tongue, bars, and lips.
• Encourages acceptance: The pleasant scent and soft material are specifically designed to make horses more willing to accept and mouth the bit, often reducing head-tossing or resistance associated with a plain metal single joint.
• Direct, simple, softened signal: As with any single joint, there's no additional link or plate diffusing the pressure — the rider's cue stays clear and direct — but the polymer takes the harsh edge off that directness.
• No leverage or added severity: As with any single-jointed snaffle, this works purely on direct pressure, with no shank or curb chain.

What it's good for

• Horses apprehensive of metal or resistant to a plain metal single joint: A useful option for horses that need the clear, straightforward signal of a single joint but respond poorly to hard metal contact.
• Young or green horses starting bit work: The scent and soft material help create positive early associations with contact, easing the introduction to bit pressure.
• Horses with sensitive lips, bars, or mouth corners: The polymer's give reduces the risk of pinching or bruising compared to a rigid metal mouthpiece.
• Cold-weather riding: Polymer stays at a more consistent, comfortable temperature than metal, which matters for horses sensitive to a cold bit, especially in winter.
• Riders wanting simple, direct communication with added comfort: Suited to horses that respond well to the clarity of a single joint but benefit from a gentler material than stainless steel.

A note on comparison to rubber

• Polymer tends to be more durable and holds its shape better than rubber over time, particularly with horses that are moderate chewers, though it's still not indestructible — persistent or strong chewers can still cause wear or damage, which typically isn't covered under warranty.
• Compared to rubber, polymer is generally firmer, so while it's gentler than metal, it may give slightly less than a soft rubber mouthpiece — meaning it's somewhat less likely to invite leaning in horses prone to pushing into a very yielding mouthpiece.

A note on classification

• The overall lateral action still depends on the cheek style (loose-ring, D-ring, eggbutt, Full Cheek, etc.) this mouthpiece is built into.
• This is generally considered a mild-to-moderate mouthpiece — softer than a metal single joint due to the material, but still carrying more of a "fold" sensation centrally than a French Link, lozenge, or mullen mouth, since the single-joint mechanics remain unchanged underneath the polymer.

Summary

A Single-Jointed Polymer bit keeps the classic, direct communication of a single-hinge mouthpiece while softening its typical harshness and adding a taste- and material-driven acceptance boost — making it a popular, comfort-focused option for horses that respond well to a single joint's clarity but need gentler material, particularly useful for young horses, sensitive mouths, or those wary of metal.
