This product is a tool for removing the brake bearing retaining ring of Shimano BB-X and other reels. With this tool, you don't have to rely on the manufacturer. We created this tool in our factory, based on the original parts' blueprints! You can repair, modify the sound, and maintain your reel yourself. We negotiated with the factory and were able to increase production and sell it at a lower price! The material is aluminum, so it is rust-resistant and lightweight. Please note that you are responsible for any problems that may arise. 《Compatible Models》 19 BB-X Technium Fireblood 18 BB-X Remare 17 BB-X Hyper Force 16 BB-X Despina 16 BB-X Larissa 16 Exsence LB 15 BB-X Technium 13 BB-X Hyper Force 13 Exsence LB 12 BB-X Remare 11 BB-X Despina 11 Exsence LB SS 10 BB-X Technium Mg 09 BB-X Technium Mg Yaen (Fishing Method) Explosive Sound Modification Shimano Lever Brake Reel Reverse Sound Unit Sound Modification Yaen (Fishing Method) BB-X 12, 18 BB-X Remare 13, 17 BB-X Hyper Force 11, 16, 23 BB-X Despina 11, 16, 23 BB-X Larissa 11, 13, 16 Exsence LB
