One-Piece Bail allows the line to travel unimpeded to the line roller. The seamless design reduces friction and decreases the chance of tangles or the line catching on the bail arm.

Shimano's exclusive manufacturing technology further advances MicroModule Gear II with a state-of-the-art gear-tooth surface design. The surfaces of the drive gear and pinion gear have been analyzed and updated from the ground up in Shimano’s pursuit of perfection to further improve the smooth gear feeling and reducing sound.

The Long Stroke Spool has a longer stroke compared to conventional spool designs. This ultimately produces a smoother line lay during retrieval and translates into increased casting distance for anglers.

The new MGL Rotor produces unprecedented light rotation within the MagnumLite family of spinning reels. Engineers redesigned the previously symmetrical MagnumLite rotor to be asymmetrical and relocated the bail arm mechanism to the opposite side of the line roller to improve the overall balance of the rotor. Combined with a lightweight line roller, titanium bail and optimum arrangement of rotor thickness, the new MGL rotor achieves up to a 14% reduction in rotational inertia to increase sensitivity to unprecedented levels. But the evolution of the MGL rotor is not limited to just reduced weight. The MGL rotor rigidity is up to 30% higher than conventional models and contributes to enhanced drag performance.

CI4 is a Shimano original material reinforced with carbon fiber that is lighter and has a higher strength than conventional resin material. CI4+ is an advanced version of the original CI4 material and is 2.5x more rigid than its predecessor. While improving lightness and rigidity, reel bodies and rotors built with CI4+ are further reduced in size and weight.

For medium and small general-purpose spinning reels, which require lighter spinning, we focused on a non-contact structure that does not compromise the lightness of the spinning. In addition to conventional water-repellent treatment, a labyrinth structure that suppresses water penetration is combined to achieve high water-resistant performance despite the non-contact nature of the structure. It is used in the stopper bearing section and line roller section.

G-Free Body technology has been developed to shift the reel's center of gravity closer to the rod. By moving the center of gravity closer to the angler’s hand, the G-Free Body helps to reduce fatigue and enhance casting comfort.
