This Sherri Cervi Signature bit by Classic Equine was designed to start a colt on the pattern. It can also be super effective on horses that are light and don't need much bit. The reins can be attached to the o-rings at the mouth for the effect of a snaffle or they can be attached to the shank rings to give you a little more stop. The gag effect teaches your horse to rate your hands in conjunction with your seat so that you can make a smooth transition into your turn while getting lift and encouraging correct lead into a turn. The dogbone will help your horse self sooth when faced with the high stress of competetive barrel racing and makes this bit have a lot of action when you pickup on the reins.
