This bit has a narrow chain port. It's very flexible. It’s a great graduation bit for your horse to step up to. It helps to relax horses too. Any time you have a bit that has this many moving parts, it will have a lot of pre-signal, which helps make horses much more willing to surrender and flex laterally for you. Plus the high leverage will help drop your horse’s head. In terms of mouth power, this is our number two bit, so it's on the milder end of the spectrum.
