The gear teeth surfaces in the MICRO MODULE GEAR 2 are finer and mesh more closely together than traditional gears, resulting in minimal power loss and a smooth, powerful winding experience. Additionally, the increased number of meshing teeth provides greater strength compared to conventional gears. This unique Shimano gear system achieves a balance of smoothness and durability.

INFINITY LOOP is a technology that allows the spool to wind the line more precisely by slowing down the up-and-down motion of the spool. With advancements in the internal structure of the reel, the speed of the spool's vertical movement has been significantly reduced. This allows the line to be wound neatly and densely onto the spool, greatly reducing line release resistance. This results in an exceptional casting feel and smooth line delivery. Additionally, the slower vertical movement of the spool reduces oscillation-induced wobbling, decreasing unnecessary vibrations transmitted to the hand and contributing to improved sensitivity.

INFINITY DRIVE is an advanced evolution of the traditional X-SHIP structure. By making the main shaft, which was previously supported by the pinion gear, non-contact and supporting it with a special low-friction bushing, sliding resistance is greatly reduced. Additionally, special surface treatments and processing have been applied to the main shaft itself to further reduce friction loss. These enhancements enable powerful winding even under high load conditions.

SILENT DRIVE involves a comprehensive redesign of the entire body and drive-related components, meticulously eliminating minute gaps, play, and vibration between parts. Areas of improvement include the drive gear, worm shaft, worm shaft pin, worm shaft gear, and slider gear, among others. This results in a new level of smooth rotational performance and a quiet, refined reeling experience.

X-PROTECT provides robust protection against water ingress into the reel by combining a labyrinth-structured waterproof wall with special water-repellent grease. In small to medium-sized spinning reels, which require lighter rotation, a non-contact structure is emphasized to maintain rotational lightness. This high waterproof performance is achieved by combining traditional water-repellent treatments with a labyrinth structure that prevents water penetration without direct contact. This technology is applied to areas such as the stopper bearing and line roller.

For larger spinning reels that require higher waterproof performance, a contact-type waterproof structure is used. Low-friction seal materials physically block seawater entry paths, achieving high waterproof performance while minimizing rotational resistance. This contact-type waterproofing is applied to the stopper bearing and line roller, with the stopper bearing achieving an IPX8 waterproof rating.

The AR-C Spool, used in Shimano spinning reels, features a special spool ring shape. The inclined spool edge creates moderate friction resistance, leading to a streamlined line release effect. This design minimizes line troubles while achieving excellent casting performance.

The Rigid Support Drag system supports the spool with two bearings located on the main shaft and inside the spool. This setup minimizes spool wobble and delivers stable, smooth drag performance.

The ONE-PIECE BAIL is a seamlessly molded bail with no joints. This design significantly reduces the likelihood of the line getting caught where the line roller and bail meet, minimizing line-related issues.
