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.

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 basic design of the entire body and drive-related parts were reviewed one by one to reduce minute rattles, gaps, and shaking between parts down to the smallest detail. It provides smooth and quiet reel rotation.

The MAGNUMLITE ROTOR is a low-inertia rotor using CI4 + construction. Not only is the overall weight reduced, but the operability and winding sensitivity of the lure are greatly improved.

The water-repellent treatment provides water-resistance even in the presence of minute gaps due to the water bead formation effect. The water resist effect can be improved without increasing rotational resistance. Furthermore, since there is no contact, there is no abrasion and the waterproofing effect lasts longer.

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.

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.

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