This Dutton bit is moderately severe. It features a 1 1/2" high port attached to a chain mouth. The high port applies pressure on the bars and the chain collapses across the bars to encourage flexion. 8" Cavalry Cheek Bits This 8" Calvary "S" cheek is one of Greg’s most popular cheeks. With excellent feel and give, these cheeks provide quick response and release for both horse and rider. The traditional cavalry shape also helps keep the horse from grabbing the shank of the bit and playing with it.
