A Ring cheek piece introduces poll pressure as well creating leverage on the mouthpiece.
The 3 Ring is our most popular version.
Our Snaffle is a popular bit due to the curved mouthpiece which distributes pressure more evenly over tongue and bars. With the offset centre link it will reduce nutcraker action and pressure points on the tongue.
The Square Twist will create more pressure points on the mouthpiece which will make it stronger than the Round Twist and Smooth.
