Rings: 2 3/4" Thickness: 10mm D-rings provide lateral control and prevent the bit from being pulled through the mouth, ensuring stability. Ergonomically designed forward-shaped mouthpiece for comfort and even pressure distribution. Soothing copper rollers glide gently across the tongue, encouraging salivation, bit acceptance, and providing a calming effect. Wheel-polished finish ensures a smooth sleek appearance and no rough or sharp edges. Medical-grade stainless steel for exceptional durability and corrosion resistance. At Cavalon, we understand that a bit is more than just a piece of equipment; it's a tool that connects you with your horse. Each Cavalon bit is carefully hand-forged by our skilled craftsmen using medical grade stainless steel to provide you a bit with quality that can be seen and felt.
