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.

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.

Parallel Body is designed to improve dynamic line flow from the reel to the first guide. On many reels the spool is aligned slightly upwards towards the rod blank, but reels with Parallel Body have the spool located at exactly 90° to the blank. The result: less line slapping on the blank as it travels towards the first guide during the cast, ultimately increasing performance.

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.

INSTANT DRAG allows the drag setting to be switched from free spool to a 'fight' setting by tightening the INSTANT DRAG lever on the front of the spool in only a few turns.

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 rotation of the bearing.
