EcoPure Jointed Full Cheek Gag Bit

A Full Cheek Gag combines the running gag action (sliding cheekpieces that lift and rotate the bit in the mouth) with the long cheek bars of a Full Cheek, offering both a strong balancing/head-raising effect and lateral steering support in one bit.

Design

• Like a standard running gag, the rings have holes through which specially adapted rounded leather or rope gag cheekpieces are threaded, running from the bridle's headpiece down through the bit ring to a smaller ring where the reins attach.
• Layered onto this is the Full Cheek element: narrow arms extending above and below the rings, positioned to prevent unwanted sliding within the mouth and to reinforce turning aids.
• When rein pressure is applied, the bit slides upward along the gag cheekpieces and rotates slightly in the mouth — the classic gag action — while the cheek bars simultaneously resist lateral movement and support steering.
• Mouthpieces vary (single-jointed for a nutcracker action, roller, high port, twisted, etc.), and severity is also influenced by the size of the rings — larger rings mean a stronger gag action.

Function

• Balance and rebalancing: The core gag action works on the horse's balance — as the bit slides up and applies poll and mouth-corner pressure, it encourages the horse to rebalance and shift weight back onto the hindquarters, discouraging leaning on the forehand.
• Combined balance and direction: This bit combines the gag action and the Full Cheek action, meaning it addresses both balance/rebalancing and directional control in a single mouthpiece — useful when a horse needs both at once.
• Reinforced steering: The cheek bars add the same lateral guidance as a standalone Full Cheek, helping keep the shoulders aligned and supporting clear turning cues even while the gag action is engaged.
• Reduced sliding/mouth stability: The full cheek arms help prevent the bit from moving excessively within the mouth, giving a steadier, more framed feel than a plain gag ring alone.
• No upper limit on lift: As with any gag, there's no built-in limit to how far the bit can rise in the mouth — strong or sustained rein pressure can lift it substantially, so it must be used thoughtfully.

What it's good for

• Strong horses that lean on the forehand or get heavy in fast work: The gag action encourages rebalancing and discourages leaning, useful for horses that pull or become unbalanced at speed.
• Horses that also need extra steering support: The Full Cheek element makes this a good choice for a horse that both needs rebalancing help and struggles with straightness or drifting through turns — addressing both issues without needing two separate bits.
• Fast, forward disciplines: Commonly used in cross-country, showjumping, and other jumping/eventing contexts where quick rebalancing and directional control both matter, especially in open, fast-paced work.
• Use with two reins or bit loops: As with other gags, it's often recommended with two reins (or bit loops/converters), giving the rider the option to use plain snaffle-style pressure most of the time and engage the gag action only when needed.

A note on use

• Because it combines two strong mechanisms (gag leverage plus full cheek lateral pressure), it's considered a more advanced, stronger bit — best suited to experienced riders with good timing and independent hands.
• Bit keepers are advisable to keep the full cheek arms stable and reduce snagging risk.

Competition legality

Like other gag bits, the Full Cheek Gag is generally not FEI dressage-legal, and is instead used in disciplines like eventing (cross-country), showjumping, and some hunting contexts where stronger control is permitted.

Summary

The Full Cheek Gag merges gag-style rebalancing action with Full Cheek steering support, making it a strong, dual-purpose option for horses that lean, rush, or get strong in fast work while also needing help with directional control — best reserved for experienced riders in disciplines like eventing and showjumping.

This combines the classic single-joint mouthpiece shape with a rubber covering or construction, softening the nutcracker action's typical sharpness through material cushioning rather than through mouthpiece design changes like a double joint would.

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, or coated in, rubber — either vulcanized natural rubber (firmer, more traditional) or a softer synthetic rubber/TPU — rather than plain metal.
• Some versions have a metal core running through the rubber for strength and shape retention, with the rubber forming the actual contact surface.

Function

• Softened nutcracker effect: The core single-joint action is unchanged — the two halves still fold upward at the center hinge under rein pressure, and the joint can still rise toward the palate. However, because the mouthpiece itself is soft and yielding rather than rigid metal, the overall sensation is considerably gentler than a stainless steel single joint, even though the underlying mechanical action is the same.
• Cushioned contact throughout: Rubber's give means the tongue, bars, and lips all experience a softer, more forgiving pressure, even at the point of the fold, compared to an unyielding metal single joint.
• Warmer, more approachable feel: Rubber stays warmer than metal, avoiding the "cold bit" sensation some horses object to.
• Direct, simple signal, softened: Riders still get the clear, straightforward communication of a single-joint mouthpiece — there's no additional link or plate diffusing the signal — but the rubber takes the edge off that directness, making the pressure feel less sharp even as the mechanical fold remains the same.
• 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 that find a metal single joint too sharp, but still respond well to the clear, direct signal of a single joint: This is often a good middle-ground option — keeping the simple, unambiguous communication of a single hinge while softening the harshness some horses feel from unyielding metal.
• Young or green horses just starting bit work: The cushioned feel can make early bitting experiences more comfortable and encouraging, while still introducing the classic single-joint action many horses will eventually encounter in metal form.
• Horses with sensitive lips, bars, or mouth corners: The rubber's give reduces the risk of pinching or bruising compared to a hard metal mouthpiece.
• Horses transitioning from an all-metal single joint due to discomfort: A reasonable step toward more comfort without changing the fundamental mouthpiece shape or moving to a double-jointed design.
• Cold-weather riding: Like other rubber and polymer mouthpieces, it avoids the unpleasant sensation of an icy metal bit in winter.

A note on leaning and durability

• As with other rubber mouthpieces discussed, the softness can be a double-edged quality — some horses, particularly those already inclined to lean or brace against contact, may find it easier to push into a yielding rubber mouthpiece than a firmer one, since there's less hard resistance to respect.
• Rubber is generally less durable than polymer or metal, especially with horses that chew or mouth their bit heavily, so it's worth checking regularly for wear, cracking, or damage.

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 at the center than a French Link, lozenge, or mullen mouth, since the underlying single-joint mechanics remain unchanged.

Summary

A Single-Jointed Rubber bit keeps the classic, direct communication of a single-hinge mouthpiece while softening its typical sharpness through rubber's natural give — making it a useful option for horses that want the clarity of a single joint but need a gentler material, though as with any rubber mouthpiece, its softness may invite leaning in horses already prone to that tendency, and it should be checked periodically for wear.
