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 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.

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.
