InfinityLoop technology delivers exceptional casting performance by drastically reducing friction on the line leaving the spool. Advancements in the internal structure and design extend the spool's oscillation to enable the spool to move up and down at an extremely low speed. This technology creates a precise winding pattern with less overlap that significantly reduces friction as the line leaves the spool during a cast. The result is smooth and exceptional casting performance, especially of light lures.

InfinityXross provides superior gear durability through industry-leading design and cutting-edge manufacturing technology. Advancements in the gear tooth design improve the surface contact and meshing between the drive gear and pinion gear. This revolutionary design efficiently distributes the load placed on the gear tooth surface across a wider area to prevent damage from stress points while significantly improving overall gear durability.

By strengthening the spool support of the main shaft, the play and fluctuation of the spool during drag operation are suppressed. The Rigid Support Drag allows smooth and consistent drag delivery, even under high load.

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.

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.

DuraCross provides smooth and reliable drag performance with incredible durability. Constructed to enhance overall durability, this revolutionary drag washer incorporates cutting-edge materials woven in a unique pattern compared to conventional drag washers. Without sacrificing a smooth drag feel, this new material is greater than 10x more durable for improved drag performance.

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.

In addition to the labyrinth structure and special water-repellent grease, this new waterproof technology uses centrifugal force to expel water to the outside, enhancing durability. A new structure has been adopted that uses a water-stopping wall on the line roller and uses the centrifugal force generated by the rotation of the rotor to expel water to the outside, instead of the conventional structure. The NEW X-Protect significantly suppresses the intrusion of foreign matter contained in water, and also protects the line roller by promoting the expulsion of water that has invaded. It suppresses unpleasant noise, provides a comfortable rotation feel, and improves durability by about three times in our test comparison.

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.
