Ky Rotary eggbutt bit, British type. Single joint 13.5 cm Used a few times, but has a used feel due to long-term storage. The following is a product description. For many years, riders have been searching for a solution to improve horse bits. The goal is to control the horse with the bit, but also to ensure smooth contact between the horse's tongue and the center joint. The mouthpiece of the Ky bit is rotary, so unlike conventional bits, there is no restriction on movement. As a result of two years of experiments and detailed tests in cooperation with horses and riders, the K.Y. Rotary bit was born and has been recognized as the best bit in the equestrian industry. Features Adopts the world's first rotary ball joint Joint There is no friction or noise in the joint area, which can cause stress to the horse, and there is no discomfort or pinching of the tongue or lips. Since there is no play in the joint, direct and gentle communication with the horse can be achieved. The left and right lengths are equal, so the bit acts evenly. The rotary joint rotates smoothly 360°. Excessive movement is not transmitted to the horse, and only the aids are accurately conveyed, so it can satisfy a wide range of users from beginners to advanced riders. The aids of "receiving/yielding", "up/down", and "left/right" can be conveyed independently and accurately.
