The MicroModule Gear system creates a smooth retrieve by utilizing smaller teeth to increase the number of contact points between the drive gear and pinion gear. Ultimately, this produces a more efficient gear train with less of a gear feel.

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.

Shimano's newest innovation in brake system technology, SVS Infinity, provides easy-to-manage, consistent spool control and brake force. With brake weights that use inner friction against the raceway during the cast, SVS Infinity controls spool speed for precision casting, especially when using lighter lures. The external adjustment knob provides for quick, precise adjustments when anglers need to adjust to the conditions or when they switch baits.

CI4 is a Shimano original 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 and is 2.5x more rigid than its predecessor. While improving lightness and rigidity, reel bodies and rotors built with CI4+ are further reduced in size and weight.

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.

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.

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.
