Reinsmans Colt Bit is a great choice when transitioning from the ring snaffle to a curb bit. The extra weight is carried by the headstall, clearly introducing poll pressure, helping teach proper head carriage. The additional weight also pre-signals the horse to rein cues allowing him to comply before the mouthpiece fully engages. The copper mouthpiece encourages salivation allowing the bit to move smoothly across the tongue and bars. Copper is a soft metal, check for signs of wear before each use.
