Herm Sprenger DUO Bits: Soft, Flexible, Steady
Discover Herm Sprenger DUO mullen mouth bits, designed to be very gentle on the horse's mouth while providing the stability and security of traditional bits. DUO bits feature a unique construction that combines a soft, flexible plastic mouthpiece with a reinforced steel cable core, creating the perfect bit for sensitive horses who prefer a gentler feel.
Food-Safe, Flexible Plastic Mouthpiece in DUO Bits
The DUO bit mouthpiece is made of soft, flexible plastic that's food-safe, solvent-free, and contains no plasticizers. This safe, non-toxic material is gentle on the horse's mouth, tongue, and bars, making it ideal for young horses, horses with sensitive mouths, or those recovering from mouth injuries. The flexible nature of the plastic allows the bit to adapt to the horse's mouth movement, promoting acceptance and relaxation.
Steel Cable Reinforcement in Plastic Bits
While the outer layer is soft and flexible, the DUO bit is reinforced with a steel cable core that makes it stable and secure. This reinforcement prevents the bit from being bitten through or damaged, ensuring longevity and safety. The steel cable provides the structural integrity needed for effective communication while the soft plastic exterior maintains gentle contact. This combination delivers the best of both worlds—softness with strength.
DUO Loose Ring Bit, Eggbut Bit & D-Ring
Choose from multiple cheekpiece options to suit your riding discipline and horse's needs. The DUO Loose Ring Bit offers freely moving rings that encourage mouthing and salivation. The DUO Eggbutt Bit provides fixed rings that prevent pinching and offer steady contact. The DUO D-Ring Bit delivers lateral support and stability for precise steering. For adjustable leverage, the DUO 3-Ring Bit offers multiple rein attachment points for varied action.
Care and Maintenance of Herm Sprenger DUO Bits
DUO bits are easy to clean and maintain. Simply rinse with water after each use and wipe dry. The food-safe plastic won't harbor bacteria or develop unpleasant tastes, and the material resists cracking or degrading with proper care. Nevertheless, as the material is much softer than conventional metal bits, the mouth piece should not come into contact woth the horse's teeth. If the surface has sharp edged teeth marks or scratches, the bit should be replaced!
More Bit Options
While DUO bits offer unique soft-yet-stable construction, SPRENGER also offers bits in other materials including NATHE bits made of thermoplastic, bits made of the SENSOGAN alloy, and of course SATINOX bits made Stainless Steel.
