X-Ship provides improved gear durability. By supporting the pinion gear on both ends with bearings, the pinion gear maintains precise alignment with the drive gear. This allows the gears to stay in the same position under the heaviest loads. The added benefit of X-Ship technology is that friction between the spool shaft and gear are eliminated. This further benefits anglers with enhanced casting performance and casting distance of lighter lures.

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 pleasure 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 special 3D-design and then formed by Shimano's cold-forging technology. 

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.

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.
