The Bit Testing Center at Dressage Extensions lets you try dressage bits before investing in something that is not an ideal solution. The Bit Testing Center allows you to ride with any bit for a two-week period for a fee of just $15.95 plus shipping. This horse bit trial program is a great way to determine which style, size and mouthpiece metal material is the ideal combination for you and your horse. (Limit 2 test bits)
