Centaur Eco Pure Full Cheek Gag BitWe love the Centaur Eco Pure Full Cheek Gag because it helps raise a horse's head and is great for twists and turns on a course. This bit takes a balanced rider with experienced hands. The Eco Pure is safer than rubber in your horse's mouth. The Jointed Full Cheek Gag from Centaur is an excellent choice for a full cheek gag snaffle bit. This awesome bit features a refined thinner mouth, better strength, and is abrasion resistant.
