X-Ship provides improved gear durability. By supporting the pinion gear on both ends with bearings, the pinion gear maintains precise alignment with the drive gear. This allows the gears to stay in the same position under the heaviest loads. The added benefit of X-Ship technology is that friction between the spool shaft and gear are eliminated. This further benefits anglers with enhanced casting performance and casting distance of lighter lures.

With amazing strength and durability, the HAGANE Gear is at the very heart of most Shimano reels. Shimano, through the application of state-of-the-art technologies, gives anglers the long-lasting smoothness and pleasure that is felt when anglers first use a reel, over and over again. No cutting work is applied to the teeth of the drive gear during fabrication, instead the entire surface is calculated in minute detail by special 3D-design and then formed by Shimano's cold-forging technology. 

SilentDrive technology benefits from a total redesign of all functional parts focused on the drive gear, worm shaft and other parts. The goal: remove unnecessary noise and vibration. In doing so, the overall tolerances are improved to a micron level, ultimately creating an overall quieter and smoother reel operation.

The spool has a special spool ring shape. This creates a rectifying effect on the line and realizes both suppression of line trouble and long casting performance.

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.

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.

CoreProtect prevents water entering the body, from under the rotor at the front of the body, and also into the Roller Bearing unit.
