Technology Features of Shimano 2026 GRAPPLER 301HG LEFT
MICRO MODULE GEAR
The gear teeth surfaces in the MICRO MODULE GEAR 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.
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.
CORESOLID BODY
This body structure integrates the level wind protector and side plate, typically separate from the frame, into a single metal piece. This design provides high rigidity, a compact size for better palming, and resistance to deformation under heavy loads. The CORESOLID BODY ensures stable retrieval and reliability during powerful fights with big fish.
SVS INFINITY
The SVS (Shimano Variable Brake System) INFINITY is a centrifugal brake system that provides both excellent casting accuracy and long-distance performance. Known for its quick startup and smooth, extended casting, it allows anglers to target even the furthest points with precision. The SVS INFINITY offers a wide range of brake adjustments, easily managed with only an external dial (when all four internal brake shoes are activated). For even finer adjustments, the internal brake shoes can be tuned.
EXCITING DRAG SOUND
EXCITING DRAG SOUND is a feature that produces a sound when the line is pulled out from the spool by a fish. Unlike traditional baitcasting reels, which typically do not emit a drag sound, this feature enhances the angler's experience by stimulating their senses, making the fight with the fish even more enjoyable.
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.
