Super Free Spool eliminates friction on the spool shaft during the cast. Standard baitcasting reels are constructed in a way that when the clutch bar is pressed down, the pinion gear is freed and can actually drag on the spool shaft. This creates friction that can limit the length of a cast. But baitcasting reels with Super Free Spool are constructed so that the pinion gear is supported by a ball bearing. When the clutch is disengaged in preparation for a cast, the pinion gear and spool shaft are kept in perfect alignment. The result: zero friction is placed upon the spool shaft and enhances casting performance.

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.

The HAGANE Body is a metal reel body with high rigidity. The body rigidity and impact resistance virtually eliminates body flexing on the reel while fighting fish. The result transforms the angler's actions directly into cranking power, increasing efficiency through strength.

By applying slight pressure to the bearing holding the spool, SilentTune reduces the vibration of the bearing during high-speed rotation. This improves the quietness while casting and the rise of the spool rotation becomes even smoother.

Shimano developed the Finesse Tune Brake (FTB) to achieve unparalleled casting performance of lightweight lures by eliminating the brake unit from the spool. This revolutionary design further reduces weight beyond traditional spool-porting designs that keep the brake unit attached. Through technological advancements, Shimano's new FTB braking system capitalizes on the centrifugal force of an angler's casting motion to apply varying amounts of magnetic braking directly to the spool during several points in the cast to provide unparalleled control — especially when fishing with lightweight lures. Compared to the traditional magnetic brake systems found in baitcasting reels that apply equal force throughout the cast — and ultimately limit casting distance — the placement of magnets within the FTB enables the magnetic brakes to apply frictionless resistance when needed most and reduces braking when it doesn't. To obtain optimum spool speed during the cast, the centrifugal force from the spool's increased speed drives the FTB magnets outward closer to the spool for added control while also minimizing the amount of braking at the start of the cast when the spool needs less control. Additionally, anglers can fine-tune the Finesse Tune Brake by adding or removing the easily identifiable magnetic brakes as needed or by utilizing the external dial to make it easy and make quick adjustments on the fly.

The Cross Carbon Drag material provides a wider range of drag settings compared to traditional drag materials. The Cross Carbon Drag provides the smoothest Shimano drag performance ever while providing anglers with increased durability.

Exciting Drag Sound technology enables drag sound on a baitcasting reel without using the function of a rattle or clicker. This ultimately makes it easy for an angler to determine whether a fish is pulling drag and provides an advantage during the fight.

S3D technology leads to significantly reduced spool vibration. By designing and constructing a balanced and uniform thin-wall aluminum spool, S3D creates an incredibly smooth feeling when casting and retrieving lures.

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.
