The new version belt guard is divided into two parts, gravel baffle and grass blocker. The gravel baffle is used to prevent gravel from entering the wheel pulley, thereby preventing damage to it. The grass blocker is to prevent weeds from getting caught on wheel pulleys when riding. We kindly remind you that after installing the grass blocker, driving in the opposite direction may involve more weeds and may even bend the grass blocker. So please choose the version based on your riding habits and feelings.
