Technology Features of Shimano 2026 NASCI 2500HG
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.
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.
INFINITY DRIVE
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
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.
ANTI TWIST FIN
The ANTI TWIST FIN is an elastic fin positioned close to the line roller. By preventing the line from sagging, it reduces the occurrence of the line being sucked into the lower part of the spool and the line being wound onto the spool while twisted.
CORE PROTECT
CORE PROTECT uses a water-repellent treatment to create a beading effect that prevents water from entering even through minute gaps. This enhances waterproofing without increasing rotational resistance. Additionally, since it is a non-contact system, it avoids wear and tear, ensuring long-lasting waterproof performance.
G FREE BODY
The G Free Body relocates the sliding functional parts needed for spool movement to the upper part of the reel body, bringing the reel's center of gravity closer to the angler's hand. This design enhances the feeling of unity with the rod, making the reel feel lighter. It also reduces casting fatigue and improves rod handling.
AR-C SPOOL
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.
ONE-PIECE BAIL
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.
