Technology Features of Shimano 2018 Surf Leader CI4 35 HOSO
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.
X-PROTECT
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.
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.
CI4+
CI4+ is an advanced material used in Shimano reels. It is a reinforced carbon fiber composite that is lighter and stronger than conventional materials, providing increased rigidity and reducing weight, which enhances the overall performance and sensitivity of the reel.
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.
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.
