The Micro Module Gear System creates a smooth retrieve. The new gear set makes use of smaller teeth and more of them. This means that there are more contact points between the drive gear and pinion gear. The result is a more efficient gear train with less 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 means the gears will stay in the same position under the heaviest loads. The added benefit is that friction between the spool shaft and gear are eliminated. This will enhance the casting performance of the reel with lighter lures, and allow for longer casts.

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

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 for either the conditions or when you switch baits.

CI4+ is the ultimate in lightweight material

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

SF was designed to eliminate friction on the spool shaft during the cast. In standard baitcasting reels, when the clutch bar is pressed down, the pinion gear is freed and actually can drag on the spool shaft creating friction that can limit the length of a cast. With SF the pinion gear is supported by a ball bearing so that when the clutch is disengaged in preparation for a cast, the pinion gear and spool shaft are kept in perfect alignment. The result is zero friction upon the spool shaft.

HEG consists of not only the gears, but also the frame, setplate, and handle-side sideplate. First we increased the size of the drive gear and the pinion gear to offer increased leverage and power. By using a one-piece frame that incorporates the setplate and adding a one-piece stamped sideplate, we have eliminated flex in the drive train that causes gears to bind under pressure.

Super Stopper anti-reverse uses a one-way stainless steel roller bearing that eliminates back-play. This provides the angler with instant hook setting power.

These stainless steel ball bearings are specially treated to drastically increase the corrosion resistance of the bearing. These bearings will last at least 10 times longer than standard stainless steel ball bearings in high salinity environments.

This drag material provides a wider range of drag settings, along with the smoothest Shimano drag performance ever.
