18.5mm Mouth Double Jointed Roller Loose Ring

A Loose Ring bit is one of the most classic and widely used bit designs, where the mouthpiece hangs on rings that move freely (rotate and slide) through holes at either end of the mouthpiece.

Design

• The rings are not fixed to the mouthpiece — they pass through holes in the mouthpiece and can rotate and slide independently, working differently and independently from the mouthpiece in comparison to Fixed Ring designs.
• Both the reins and the bridle's cheekpieces typically attach to the same free-moving ring.
• Because the ring moves independently of the mouthpiece, the mouthpiece itself has a small amount of side-to-side and rotational play in the horse's mouth.

Function

• Freedom for the tongue: The independent movement gives the horse more freedom to use their tongue, allowing them to place the pressure from the mouthpiece either higher or lower in the mouth, whichever they prefer.
• Constant subtle movement: The free-moving rings allow the mouthpiece to shift and rotate slightly with the horse's mouth movements, jaw motion, and rein aids. This creates a "self-adjusting" quality rather than a fixed, static pressure point.
• Encourages mouthing and softness: The slight movement can encourage a horse to mouth and play with the bit, which some trainers use to promote relaxation, salivation, and acceptance of the bit rather than a horse "locking" onto a fixed contact.
• Even pressure distribution: Because the ring can rotate and reposition itself, pressure tends to distribute more evenly across the bars and lips as the horse moves its head, rather than concentrating in one spot.
• No leverage/poll pressure: Like other true snaffles, the loose ring has no shank or curb chain, so it functions purely on direct pressure, with no leverage action on the poll.
• Less lateral/steering support: Unlike the D-ring or Full Cheek, there are no flat sides or bars pressing against the face, so it offers minimal help with turning cues — the horse must rely more on rein aids alone for direction.
• Risk of pinching: The moving parts (where the ring passes through the mouthpiece) can occasionally pinch the lips or corners of the mouth, particularly with certain mouthpiece designs or if the bit is fitted incorrectly.

What it's good for

• Horses that lean on the bit or feel stiff: The Loose Ring is a good choice for a horse that prefers to lean on the bit and can feel stiff, since the moving parts are harder to brace against than a fixed contact point.
• Horses that respond well to a "softer," moving feel: The subtle motion can help horses that tend to lean, brace, or get heavy on a fixed contact, since the moving bit is harder to "lock onto."
• Encouraging relaxation and acceptance of the contact: Widely used to promote chewing, salivation, and a relaxed jaw, especially in dressage training at all levels.
• Experienced horses with established steering: Since it offers minimal lateral guidance, it suits horses that are already confirmed in their steering and don't need extra directional reinforcement from the bit itself.
• General riding and competition use: It's an extremely popular, versatile, all-purpose bit used across nearly every discipline — dressage, showjumping, eventing, hacking, and more.
• Riders wanting a classic, adjustable feel: Its independent movement gives riders a very traditional, "give and take" feel through the reins.

A note on fit and accessories

• Because the ring can slide through the mouthpiece, it's important the rings are large enough (or fitted with Bit Guards) to prevent the ring from pulling through the mouth or pinching the lips against the sides of the mouth.
• Bit Guards: Using Bit Guards will reduce movement of the rings, if a more stable feel on the reins is preferred. When correctly fitted, the hole where the bit ring passes through should sit just on the corner of the mouth.
• Mouth Corner Tape: To avoid any pinching, we recommend using our Mouth Corner Tape.
• Mouthpiece choice: The choice of accompanying mouthpiece is also worth considering — for example, for a playful mouth, a more stable mouthpiece design may be preferable to complement the Loose Ring's natural movement.

Competition legality

The loose ring is FEI-approved for dressage and permitted across virtually all major disciplines and competition levels, making it one of the most universally accepted bit designs.

Summary

The Loose Ring bit is valued for its freedom of movement, even pressure distribution, and encouragement of a soft, relaxed mouth, making it a classic all-purpose choice — particularly well suited to horses that lean or feel stiff, or those with established steering that benefit from a bit that doesn't lock into one position, though it offers less lateral/steering support than fixed-cheek designs like the D-ring or Full Cheek.

This describes an all-polymer double-jointed mouthpiece, where even the center roller is made of the same soft, flexible material as the outer bars, rather than a metal roller (like brass or copper) set into a polymer mouthpiece. It's one of the gentlest, most fully "soft" bit combinations available.

Design

• The mouthpiece has a double-jointed structure — two outer sections plus a center piece — but instead of a flat plate or metal lozenge, the center features a rotating roller made entirely of polymer.
• Both the outer bars and the roller are typically made from the same "space age" polymer, often apple-scented, giving a consistent soft, warm feel across the entire mouthpiece with no metal contact points at all (aside from the rings/cheeks themselves).
• The roller sits at the center joint and rotates freely, similar in concept to a metal roller, but softer to the touch.

Function

• Eliminates the nutcracker effect: As with any double-jointed mouthpiece, the two joints prevent the sharp folding/pinching action of a single joint, spreading pressure more evenly across the tongue and bars.
• Softer overall feel than a metal-roller version: Because the roller itself is polymer rather than metal, there's no cold, hard metal anywhere in the mouth — the entire mouthpiece experience is warm and give-y, which can matter for horses especially sensitive to or apprehensive of metal.
• Gives the tongue something to engage with: Like metal rollers (brass, copper), the polymer roller offers the horse's tongue something to play with, which can help keep a fidgety or tense mouth quieter and more settled by redirecting nervous tongue movement into a controlled, contained motion.
• Encourages acceptance: The pleasant scent and consistently soft material throughout (bars and roller alike) is aimed specifically at improving bit acceptance, especially in horses wary of metal.
• Independent side movement: The double-joint construction allows each side of the mouthpiece to move somewhat independently, offering clearer lateral and flexion cues than a single joint.
• No leverage or added severity: This remains a true snaffle, working purely through direct pressure.

What it's good for

• Horses that are particularly averse to metal, or have had negative associations with a bit: Because there's no metal anywhere in the mouthpiece (aside from any internal core, which is usually not in direct contact), this is one of the softest, most approachable options for rebuilding trust and comfort.
• Very sensitive-mouthed or apprehensive horses: The combination of a soft polymer roller and soft polymer bars minimizes hard contact points throughout the entire mouth.
• Young or green horses learning to accept a bit for the first time: The gentle, fully soft mouthpiece plus the roller's engaging quality make this an approachable, encouraging introduction to contact.
• Fidgety or "busy-mouthed" horses: The roller gives a constructive outlet for a horse that wants to move its tongue or fuss with the bit, without introducing a firmer metal element.
• Advanced or precise work where a mild mouthpiece is still needed: Some versions of this design are specifically noted as suitable for more advanced training, since the double joint still allows fairly clear, independent rein action despite the overall softness.

A note on limitations

• Because there's no metal roller and no metal center piece, this combination doesn't offer any taste-driven salivation boost the way a copper or blue steel roller would — its comfort benefit comes purely from material softness and the tongue-engaging roller action, not from taste stimulation.
• Polymer mouthpieces, including rollers, can be chewed and damaged over time, particularly by strong or persistent chewers, so periodic inspection for wear or bite marks is worthwhile (and typically not covered under warranty by manufacturers).

A note on classification

• The overall lateral action still depends on the cheek style (loose-ring, D-ring, Full Cheek, Baucher, etc.) this mouthpiece is built into.
• This combination sits at the very mild end of the spectrum, prioritizing maximum softness and acceptance over any added control or taste-based salivation boost.

Summary

A Double-Jointed Polymer bit with a polymer roller offers a fully soft, all-polymer mouthpiece experience — no metal contact points, a gentle double-jointed profile, and a roller for the tongue to engage with — making it one of the gentlest, most approachable bit combinations available, particularly well suited to horses wary of metal, very sensitive mouths, fidgety horses, or young horses just learning to accept contact.
