Contour Double Jointed Flat Eggbutt Bit

A Flat Eggbutt refers to a standard eggbutt-style bit where the ring has a flat, flush, oval ("egg") shape at the point where it meets the mouthpiece — as opposed to variations with a curved, anatomically shaped, or bulged ring designed to follow the contour of the lips more closely.

Design

• The defining feature of any eggbutt is the fixed, oval-shaped joint between the mouthpiece and ring, which sits flat and flush against the corners of the horse's mouth.
• Unlike a loose-ring snaffle, the ring does not rotate freely — it's fixed relative to the mouthpiece, though it doesn't offer the lateral bar support of a D-ring or Full Cheek.
• The "flat" version has a simple, straight-faced ring profile (rather than a curved, dished, or "anatomic" ring shape found in some premium designs), giving a traditional, no-frills eggbutt silhouette.
• Reins and cheekpieces both attach to the same ring, at the same point.
• The mouthpiece itself can vary widely — single-jointed, double-jointed, French link, mullen, or ported — independent of the ring style.

Function

• No pinching: Because the joint is flat and fixed rather than a rotating ring, there's minimal risk of the mouthpiece pinching the lips or corners of the mouth — one of the main reasons riders choose an eggbutt over a loose-ring.
• Stable, quiet mouthpiece: The fixed ring reduces rotation and sideways slide compared to a loose-ring, giving a steadier, more predictable feel and helping the horse settle into a consistent contact.
• Moderate lateral support: The eggbutt offers more directional guidance than a loose-ring, since the fixed ring pushes lightly against the face during a turn, but less than a D-ring or Full Cheek, since there are no extended bars or straight edges to reinforce the aid — it sits as a genuine middle ground.
• Encourages forward stretch: The flat, stable design is often noted for giving a horse the confidence to stretch forward and down into contact, since the mouthpiece doesn't shift unpredictably.
• No leverage/poll pressure: As with all true snaffles, it works purely on direct pressure — no shank, no curb chain, no leverage action on the poll.

What it's good for

• Young horses starting out: Widely regarded as an excellent first bit, since the stable, non-pinching design helps a green horse learn to accept and trust contact without unnecessary distraction from a moving ring.
• Sensitive-mouthed horses: The lack of pinching and rotation makes it comfortable for horses that are fussy or reactive in the mouth.
• Horses that need a little steering support but not a lot: Sits between the loose-ring (minimal support) and the D-ring/Full Cheek (stronger support), suiting horses that are fairly straight but occasionally benefit from light reinforcement.
• Riders wanting a simple, all-purpose bit: One of the most versatile and widely used cheek designs across nearly every English discipline — dressage, showjumping, eventing, and general schooling.
• Beginner riders: The stable, predictable feel is forgiving of less experienced or less "quiet" hands, since there's less moving hardware to create unintended noise in the horse's mouth.

Competition legality

The Flat Eggbutt is FEI-approved for dressage and accepted across virtually all disciplines, since it remains a true snaffle with no leverage action.

Summary

The Flat Eggbutt offers a traditional, no-pinch, moderately stable snaffle option — sitting neatly between the free movement of a loose-ring and the stronger lateral support of a D-ring or Full Cheek — making it one of the most popular, versatile, all-purpose choices for young horses, sensitive mouths, and riders wanting a simple, comfortable, mild bit.

This adds a curved, "contoured" mouthpiece shape to the all-polymer, double-jointed-with-roller design discussed previously — an ergonomic refinement aimed at fitting the natural shape of the horse's mouth more closely, on top of the softness already offered by an all-polymer build.

Design

• The mouthpiece retains the core double-jointed structure with a polymer roller at the center — soft polymer bars, a soft polymer rotating roller, no metal contact points in the mouth.
• The key addition is that the mouthpiece is contoured/curved rather than straight — shaped to better follow the natural curve of the tongue and the contours of the mouth, rather than sitting as a straight bar across it.
• Internally, most polymer bits of this style have a stainless steel core running through the mouthpiece for strength, with the polymer molded around it — the steel isn't in direct contact with the mouth, it's just there for structural durability.

Function

• Better anatomical fit: The curved shape is designed to sit more naturally against the horse's mouth, reducing pressure points that a straight mouthpiece might create against the tongue or bars, particularly for horses with less common mouth conformations.
• Eliminates the nutcracker effect: As with any double-jointed mouthpiece, the two joints prevent the sharp folding/pinching action of a single joint.
• Fully soft mouth experience: Because both the bars and the roller are polymer, there's no cold or hard metal anywhere in the mouth — the contoured shape adds to this by removing any awkward straight-edge pressure as well.
• Engages the tongue: The polymer roller gives the horse's tongue something to roll and play with, which can help keep a fidgety or tense mouth quieter and more settled.
• Encourages acceptance: The pleasant scent (commonly apple), soft material, and now-improved anatomical fit are all aimed at maximizing comfort and reducing any reason for a horse to resist or brace against the bit.
• Reduces tongue pressure specifically: The combination of the curved shape and central roller is often described as specifically working to reduce direct tongue pressure compared to a straight double-jointed mouthpiece, since the contour allows the tongue more natural room.
• No leverage or added severity: This remains a true snaffle, working purely through direct pressure.

What it's good for

• Senior horses or those with dental issues: The contoured shape combined with full polymer softness is frequently recommended for older horses or those with dental problems, since it minimizes hard contact points and adapts more comfortably to an aging or compromised mouth.
• Horses with unusual mouth conformation: A horse with a particularly low palate, thick tongue, or other atypical mouth shape may find a contoured mouthpiece considerably more comfortable than a straight one.
• Very sensitive-mouthed or apprehensive horses: As with the non-contoured polymer/roller combination, this remains one of the softest options available, now further refined for comfort.
• Horses transitioning away from metal bits due to discomfort: Particularly useful for horses that have become fussy, resistant, or uncomfortable in more traditional bits, since it addresses both material softness and anatomical fit.
• Young or green horses learning to accept a bit: The gentle, well-fitting mouthpiece plus the roller's engaging quality make for an especially encouraging introduction to contact.
• Fidgety or "busy-mouthed" horses: The roller offers a constructive outlet for tongue movement, same as the non-contoured version.

A note on limitations

• As with the non-contoured all-polymer version, this combination offers no taste-driven salivation boost from a metal roller — comfort and acceptance come from material softness, scent, and anatomical fit rather than any metal-taste stimulation. (Some manufacturers offer a copper-roller contoured version instead, which adds that salivation benefit if desired.)
• Polymer components, including the roller, can be chewed and worn over time, so periodic inspection is worthwhile, and manufacturers typically don't cover bite damage under warranty.

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 combination sits at the very mild end of the spectrum, adding anatomical refinement on top of an already soft, acceptance-focused design.

Summary

A Double-Jointed Contoured Polymer bit with a polymer roller offers a fully soft, all-polymer mouthpiece shaped to fit the natural contours of the mouth, combined with a roller for tongue engagement — making it one of the gentlest, most anatomically considerate bit options available, particularly well suited to senior horses, horses with dental issues or unusual mouth conformation, and any horse needing an especially comfortable, encouraging approach to bit contact.
