Shimano 2025 TWIN POWER XD

“HAGANE” is more than just a material name; it’s a design philosophy centered around creating reels that offer unmatched longevity and smoothness. The term "HAGANE" itself, which means "steel" in Japanese, symbolizes strength and resilience. However, in Shimano's context, it transcends traditional interpretations, representing a suite of advanced technologies aimed at enhancing performance and durability. In other words, when they say "HAGANE", they do not actually mean that HAGANE(= steel) is used. “HAGANE” promises robustness that can be used with peace of mind even in the harshest of conditions, an unchanging, exquisite winding feel, and winding power that exceeds the imagination."HAGANE Gear" or "HAGANE Body" is Shimano's engineering concept and philosophy.

X-SHIP features an enlarged drive gear, optimal positioning of the pinion and drive gears, and two-point support for the pinion gear with bearings. This robust gear engagement maintains smooth and efficient reeling even under heavy loads.

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.

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.

The MGL Rotor, featuring an asymmetrical rotor design, aims to enhance operability and sensitivity, achieving an extraordinary level of rotational lightness. With reduced inertia, the reel starts rotating with minimal effort and can be stopped with equally light force, offering improved control and responsiveness.

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 Long Stroke Spool features a design that extends the width of the spool's line-winding area. This reduces line reduction during the latter part of the cast, contributing to improved casting feel and increased casting distance.

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.

A-RB bearings feature a special anti-corrosion treatment that significantly improves their rust resistance. The SA-RB takes this further by sealing the sides with anti-corrosion materials, greatly reducing salt crystallization and salt damage inside the bearing.
