This product is the lightest, essential item optimized for the two-gun style that originated in the sacred land of Hinoki. If you want to improve the extension function, the feel, and the instantaneous hooking performance, please set up the Aero MAX Boost Spacer and the various Hibara MAX extension adapters. The opening of the intake part, which has been machined and tuned to reduce weight, is usually set facing downward, but you can remove the screw in the center with the included wrench and set it facing upward. You can tune in. If the insertion into the reel hole is loose, use the VARIVAS joint spacer. Since it uses a double nut system, be sure to tighten each nut firmly to secure the wing.
