The Cheltenham Sliding Gag bit is designed to be used with gag cheeks. Two sets of reins are often recommended to help stop the horse from leaning on the bit or for when more control is needed. Sliding gag bits can help to lift the front end and encourage your horse to balance on the hind end.  Ideal for jumpers and cross country horses. Made from polished stainless steel, the mouth diamter is 14mm and the cheek height is 75mm.
