Thank you for viewing. This is a bearing addition set for the line roller of Shimano's low-cost reels. By adding a bearing to the line roller and allowing it to function properly, it improves line winding and reduces troubles, leading to stable casting distance. The number of parts is small, and assembly is easy. If you wish to change the line roller bearing to a ceramic ball, it will be an additional 1200 yen. If you would like handle knob bearings, 2 pieces can be included for an additional 700 yen.
