“HAGANE”

“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.

MICROMODULE GEAR

The MICROMODULE GEAR system features finer gear teeth that mesh more closely than traditional gears, reducing power loss and creating a smooth, powerful retrieve, complemented by a precisely engineered body housing. Compared to previous Shimano gears, vibration levels are reduced to less than half. The increased number of meshing teeth also ensures greater strength, making this a unique Shimano gear system that balances smoothness with durability.

X-SHIP

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.

SVS (Shimano Variable Brake System)

This centrifugal brake system represents a pinnacle of design, delivering rapid spool startup and a smooth, extended casting trajectory. The braking section of the 21 Scorpion MD features an 8-pin SVS setup, which, when combined with a low-inertia spool that has been thinned and narrowed, enables precise brake control while maintaining impressive casting distance. Even with large, air-resistant lures like giant baits, the line stays firmly in place on the spool during casts, effectively preventing backlash.

S3D SPOOL

The S3D SPOOL features an entirely redesigned cutting method, significantly enhancing the spool's precision. As a result, this design improves the smoothness and reduces vibrations during casting, leading to a quieter and more stable performance.

SA-RB

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.

SUPER FREE SPOOL

SUPER FREE SPOOL is a system where the spool shaft is supported by only two bearings when the reel's clutch is disengaged. This design minimizes spool wobble and eliminates rotational resistance, allowing for exceptionally smooth and light spool free performance.
