TRUST Equestrian has produced no less than 16 different dressage curb bits in four sizes. Because there is a lot of variation in the tongue of a horse, there are four different heights of the mouthpiece. You have the option from a straight bar to a high port. New in the collection are the TRUST non-fixed bits, the pumping effect allows for more movement of the bit. Of course, TRUST Equestrian also offers a range of Bradoon bits, which are available in six sizes to suit every horse. Each and every TRUST bit is anatomically shaped and made for the modern horse to ensure a perfect fit.
