Ideal for practice and slow work. The Smooth Snaffle mouthpiece was designed for that sensitive or light mouthed horse. The long shank offers plenty of whoa while maintaining the flexion and bend required.This is great for a young horse and a good transition bit from an O-Ring Snaffle. The Extended Gag Feature offers bend and flexion of the poll. If you ride with a combination bit, this is a good alternative to practice in. By doing this, it helps maintain the effectiveness of your combination bit. This bit comes with a chain curb but can be used with a nylon string curb as an option. With a string curb you will have more bend but less whoa.
