XRAY have introduced the new medium hardness rubber shock membrane cell set for XB8 and XT8. The cell shock membranes have less air gap that helps to generate more grip, and they offer increased rebound and traction. The specially-formulated rubber material of the shock membrane ensures equal damping characteristics from the beginning of the race to the end, even after extreme operation. The membranes come in sets of four.
