EASY-CHANGE Riser System Rear Risers Pony/Jump are available in 4mm or 8mm thickness. Sold in pairs. EASY-CHANGE Riser System Rear Risers allow you to adjust the balance of your saddle seat at the rear of the saddle. We recommend Rear Risers for your Bates and Wintec saddle if the cantle needs to be raised for optimal balance and stability in the saddle seat. Pony/Jump Risers have a smaller profile than standard risers to fit the slightly smaller panels of Bates and Wintec pony and jumping saddles.
