HORZE Rubber Oval Link Eggbutt Snaffle Bit

The HORZE option features an oval link double jointing paired with a rubber-covered mouthpiece. Eggbutt cheekpieces help maintain even tongue pressure and keep the bit stable in the horse’s mouth. Rubber coverage aims to soften contact, potentially reducing mouth tension. This bit is suitable for riders seeking a balanced feel with a gentler mouthfeel and straightforward rein communication. It supports softer transitions between gaits while preserving steering control.
Korsteel Soft Rubber Jointed Eggbutt Snaffle Bit, 5″

This Korsteel model uses a thicker rubber mouthpiece that softens contact at the corners and bars. The broad contact distributes rein pressure over a larger surface, potentially reducing sensitivity. It is designed to encourage chewing and salivation, which can promote a calmer, more relaxed horse during schooling sessions. The jointed eggbutt design assists with steering without excessive leverage on the mouth.
Happy Mouth Round Ring Eggbutt Shaped Mullen Mouth, 5″

The Happy Mouth bit uses a shaped Mullen mouthpiece with an inner twisted wire for flexibility, backed by a space-age polymer that aims for a gentler bite. An Apple scent is noted to aid acceptance by some horses. The round ring design minimizes pinching and offers straightforward rein response, with a focus on a soft, forgiving feel for sensitive mouths. This option supports calmer mouth activity and easier chewing without heavy mouth pressure.
Korsteel Soft Rubber Mouth Jointed Dee Ring Snaffle, 5″

In this Dee Ring design, the mouthpiece is softly rubber-coated to reduce friction at the corners, with a single jointed mouthpiece delivering a nutcracker action. The rubber mouthpiece provides a warmer, more comfortable feel compared to stainless options. The Dee ring encourages straightness in the horse’s head carriage while maintaining clear rein cues for the rider.
JP Korsteel Copper Oval Link Eggbutt Snaffle, 4.75″

This JP Korsteel model uses a copper oval link with an eggbutt design to minimize roof-contact and promote cooperative behavior. The copper content is intended to enhance salivation and acceptance, aiding communication between horse and rider. The oval link helps distribute pressure evenly across the mouth, which can support a smoother transition through gaits and clearer direction control.
Buying Guide: Rubber Eggbutt Snaffle Bits
Key considerations when selecting a rubber eggbutt snaffle include mouthpiece softness, joint configuration, and overall comfort for the horse’s mouth. Rubber mouthpieces are often preferred for horses with sensitive mouths or those prone to mouthiness, as they can reduce pinching and provide a more forgiving contact. Consider the following perspectives:
- Mouthpiece design: Eggbutt bits stay balanced in the mouth, with cheeks helping keep the bit from pinching the lips. Double joints and Mullen mouthpieces influence how pressure is distributed across the bars and tongue.
- Rubber coverage: Full rubber-coated mouthpieces soften contact. Some designs use inner cores or soft rubber layers that balance flexibility with durability.
- Cheekpiece style: Dee ring and eggbutt configurations affect bit stability and steering feel. Dee rings often help with straightness and head position.
- Rider goals: For light contact and teaching, look for gentle pressure and encouraging chewing. For more established riders, a slightly firmer feel with consistent rein cues may be preferred.
- Maintenance: Rubber mouthpieces require regular cleaning to prevent residue buildup and ensure consistent texture and bite signals.
Users should assess their horse’s comfort, chewing behavior, and response to rein pressure when choosing among these options. For horses with sensitive mouths or tendency to resist the bit, rubber-covered mouthpieces and gentler joint configurations tend to offer better acceptance and cooperation during rides or schooling sessions. Always consult a qualified trainer or veterinarian if you notice unusual mouth tension, withdrawal, or reluctance to work with a bit.
