By using magnesium material, a lightweight material also used in high-end reel bodies, for the spool, we have achieved an ultra-lightweight weight of approximately 8.8g. A light spool can reduce the moment of inertia, making it easier to increase the rotation speed and cast lightweight lures used in bait finesse. Line capacity: 0.235mm (8lb) - 50m. The brake side is equipped with a cam-type movable plate. When the spool rotation speed increases, the movable plate pops out to the brake side. By increasing the magnetic flux lines that hit the movable plate, it is possible to apply stronger brakes at high rotation speeds.
