Copper Roller Full Cheek Bit

A Full Cheek bit (also called a "Full Cheek Snaffle") is a fixed-cheek bit design with long, straight bars (cheekpieces) extending both above and below the mouthpiece ring on each side.

Design

• The mouthpiece sits on rings, similar to a standard snaffle, but rigid bars extend upward and downward from these rings, parallel to the horse's face.
• The upper bars typically have small "keepers" or loops through which the bridle's cheekpieces can be attached, holding the bars upright and flat against the face.
• The reins attach either to the main ring itself or sometimes through slots in the cheek bars, depending on the design.
• Unlike a loose-ring snaffle, the mouthpiece cannot slide side-to-side through the horse's mouth because the fixed cheeks prevent it.

Function

• Framed, stable feel: The sidepieces give the bit a "framed" quality in the mouth, helping the horse feel steady and secure in the contact.
• Lateral/turning support: The long cheek bars act as a visual and physical guide. When rein pressure is applied on one side (e.g., in a turn), the opposite cheek bar presses gently against the side of the horse's face, reinforcing the turning aid. This makes it especially useful for steering and bending, and helps keep the horse's shoulders in place through turns.
• Prevents pulling through the mouth: The bars stop the bit from sliding sideways or being pulled through the mouth, which can happen with loose-ring snaffles on horses that evade contact by turning their head sharply or leaning on one rein.
• Protects the mouth corners: The fixed sidepieces prevent the mouthpiece from pinching or rubbing at the corners of the mouth, a common irritation with bits that can slide or rotate more freely.
• Mouthpiece stability: Because the cheeks are fixed, the bit sits more quietly and predictably in the mouth compared to a loose-ring design.
• No poll leverage: Like the Baucher, the Full Cheek has no lower shank/curb chain combination, so it does not create true leverage or added poll pressure — it acts on the same direct, non-leverage principle as any snaffle.

What it's good for

• Green or young horses: The visual/physical cheek support helps teach steering and lateral cues, since the horse gets a clear tactile signal from the cheek bar pressing against its face during a turn. It's considered a great, comfortable starting bit for a youngster.
• Horses that struggle with straightness: The lateral guidance helps riders reinforce direction, useful for horses that tend to drift, bulge through a shoulder, or evade turning aids.
• Horses that root or lean, or try to pull the bit through their mouth: The fixed cheeks resist this kind of evasion better than a loose-ring.
• Horses with sensitive mouth corners: The stability and corner protection make it a comfortable option for horses prone to rubbing or pinching.
• Driving/harness horses: Full cheeks are traditional in driving because they help prevent the bit sliding through the mouth when direct rein contact isn't always available (as with long driving reins), and offer better steering cues without a rider's leg aids.
• Young horses in lunging or early ridden work: Often used with "bit keepers" (small loops connecting the upper cheek to the browband/headstall) specifically to reinforce the "give and take" steering response horses are taught early on.

Competition legality

The Full Cheek is FEI-approved, including for dressage, making it a permitted option at all levels of affiliated competition.

A note on safety

Full cheek bits carry a practical risk: the protruding cheek bars can catch on equipment, fencing, or other objects. For this reason, they're almost always used with bit keepers — small leather loops attaching the upper cheek to the bridle's cheekpiece — to keep the bars stable and reduce the chance of snagging.

Summary

The Full Cheek is valued for its steering/lateral assistance, mouth stability, and comfort, making it a popular, FEI-legal choice for young horses learning directional cues, horses needing extra straightness support, or driving horses — rather than for any leverage or "stronger" stopping power, since mechanically it functions as a direct-pressure snaffle.

This describes another common mouthpiece material and design combination — like the blue steel and polymer versions discussed earlier, it can be built onto various cheek styles (loose-ring, D-ring, eggbutt, Full Cheek, or a gag), with the cheek choice still determining the bit's lateral action, while these features shape the feel and taste in the mouth.

Breaking down the features

• Stainless steel mouthpiece:
• The most common bitting material, prized for being durable, tasteless, and non-rusting.
• Unlike sweet iron or blue steel, stainless steel does not oxidize or develop a "sweet" surface taste — it stays neutral, smooth, and consistent over time.
• Easy to clean and maintain, with no risk of staining tack or requiring special upkeep, making it a practical, reliable, low-maintenance default choice.
• Because it doesn't naturally encourage salivation the way sweet iron or copper does, any taste-driven acceptance benefit in this combination comes specifically from the copper roller rather than the mouthpiece itself.
• Double-jointed construction:
• Made up of three parts — two outer sections plus a center link — rather than a single hinge.
• Reduces the sharp "nutcracker" action of a single-jointed mouthpiece, distributing pressure more evenly across the tongue, bars, and corners of the mouth rather than concentrating it in a V-shape against the palate.
• Generally regarded as a more comfortable profile than a single joint, while still giving clear, direct signals since stainless steel itself has no "give."
• The size and thickness of the center link affects how much tongue pressure is applied — a thicker center piece increases tongue contact, so this can be tailored somewhat to the horse's mouth conformation.
• Copper roller:
• A small rotating roller or disc, typically pure copper, set into the mouthpiece (often at the center joint).
• Copper has a naturally sweet taste that horses generally find pleasant, which encourages salivation and helps keep the mouth soft, moist, and relaxed.
• Gives the tongue something to roll and play with, which can help keep a fidgety or tense mouth quieter and more settled, redirecting nervous tongue movement into a small, controlled motion.
• Because copper is a warm, soft metal relative to stainless steel, the roller also introduces a touch of warmth and "give" into an otherwise firm, unyielding stainless mouthpiece.

What it's good for

• Riders wanting a durable, low-maintenance, all-purpose mouthpiece with an added acceptance boost: Stainless steel's practicality (no rust, no staining, easy cleaning) combined with copper's salivation-encouraging properties makes this a popular "best of both worlds" choice.
• Horses that need encouragement to relax the jaw and accept contact, but don't require a full sweet-iron or polymer mouthpiece: The copper roller alone often provides enough taste stimulation for horses that aren't especially resistant or apprehensive.
• Horses that fidget or seem to want to move their tongue: The roller gives a controlled outlet for that tendency, similar to the brass-roller and other-roller variations discussed earlier.
• General schooling and everyday use across disciplines: Because stainless steel is the standard, widely accepted material in most rulebooks and doesn't require special care, this combination suits riders who want a dependable daily-use bit with a mild comfort feature built in.
• Horses transitioning between mouthpiece types: A reasonable middle-ground option for a horse that doesn't need the stronger sweet-iron/salivation effect of blue steel, nor the extra softness of a polymer mouthpiece, but could still benefit from some encouragement toward acceptance and relaxation.

A note on classification

• As with the other mouthpiece/material combinations, the overall severity and steering action depends on the cheek style the mouthpiece is built into — the same double-jointed, copper-roller mouthpiece will behave differently on a loose-ring versus a Full Cheek or gag bit.
• This mouthpiece is generally considered mild to moderate, with the double joint keeping it comfortable and the copper roller adding a modest acceptance/relaxation benefit, without the stronger salivation-boosting effect of sweet iron/blue steel or the extra softness of polymer.

Summary

A double-jointed stainless steel mouthpiece with a copper roller combines the durability and neutrality of stainless steel with the even pressure distribution of a double joint and the salivation-encouraging taste of a copper roller — making it a practical, low-maintenance, and moderately comfort-focused choice suited to a wide range of horses, particularly those needing a small nudge toward relaxation and acceptance without a specialized sweet-iron or polymer mouthpiece.
