With amazing strength and durability, the HAGANE Gear is at the very heart of most Shimano reels. 

Shimano, through the application of state-of-the-art technologies, gives anglers the long-lasting smoothness and enjoyment that is felt when anglers first use a reel, over and over again. No cutting work is applied to the teeth of the drive gear during fabrication; instead, the entire surface is calculated in minute detail by a special 3D design and then formed by Shimano's cold-forging technology. The result is assured resilience. HAGANE Gear is the result of Shimano's endless pursuit for durability — this strength and power of forged metal continue to represent the fundamental concept of Shimano reels.

The MICROMODULE Gear II has evolved with Shimano's unique manufacturing technology and a state-of-the-art gear-tooth surface design. The drive and pinion gear surfaces have been analyzed and updated from the ground up in Shimano's pursuit of perfection to further improve the smooth gear feeling and reduce sound.

X SHIP provides improved gear performance. Large diameter drive gear, optimally positioned pinion gear and drive gear, and two points bearings supported pinion gear produce light reeling under load.

The use of lightweight and rigid metals such as aluminum and magnesium firmly suppresses deflection, distortion, and torsion of the reel. This protects delicate gear meshing and enables smooth reeling.

For medium and small general-purpose spinning reels, which require lighter spinning, we focused on a non-contact structure that does not compromise the lightness of the spinning. In addition to conventional water-repellent treatment, a labyrinth structure that suppresses water penetration is combined to achieve high water-resistant performance despite the non-contact nature of the structure. It is used in the stopper bearing section and line roller section.

G FREE BODY technology has been developed to shift the reel's center of gravity closer to the rod.

G FREE BODY technology has been developed to shift the reel's center of gravity closer to the rod. By moving the center of gravity closer to the angler’s hand, the G FREE BODY helps to reduce fatigue and enhance casting comfort.

The spool has a special spool ring shape. This creates a rectifying effect on the line and realizes both suppression of line trouble and long casting performance.

The LONG STROKE SPOOL has a longer stroke compared to conventional spool designs. It contributes to improved casting feel and distance.

CI4 is a resin material reinforced with carbon fiber that is lighter and has a higher strength than conventional resin material. CI4+ is an advanced version of the original CI4 material.The rigidity and durability have been greatly improved from original CI4 material while maintaining the lightness of the material, making it possible to reduce the size and weight of the reel.

By strengthening the spool support of the main shaft, the play and fluctuation of the spool during drag operation are reduced. The RIGID SUPPORT DRAG allows smooth and consistent drag delivery.

The CROSS CARBON DRAG provides the smooth drag release and the durability.

S A-RB bearings are put through the same process as Shimano’s A-RB bearings but feature shields on both sides of the bearings. These shields reduce the possibility of salt or sand inhibiting the rotation of the bearing.

ONE-PIECE BAIL allows the line to travel unimpeded to the line roller. The seamless design reduces friction and decreases the chance of tangles or the line catching on the bail arm.
