The Reinsman Circle R Performance Bit features a medium leverage shank and a long purchase to create more control and a quicker response from your horse. The 3 pc. snaffle bit breaks closer to the bars for a new feel, making this an ideal change for a horse whose mouth is showing signs of losing responsiveness. The snaffle horse bit's sweet iron mouthpiece is designed to rust, which increases your horse's production of saliva, creating a wet, soft mouth. Also, the copper roller will aid in moisture production and help pacify a nervous horse who likes to chew on a bit.
