HAGANE is a Shimano reel design concept created to withstand continual use and extreme abuse. HAGANE is an innovation with built-in toughness and durability that works alongside Shimano's precision engineering. HAGANE is for all anglers.

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.

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.

Infinity Drive technology is an advanced structure that produces more powerful and exceptionally light winding within conventional and low-profile reels. This innovative design supports the pinion gear with the spool shaft rather than supporting the pinion gear with a bearing on the spool side. Infinity Drive within low-profile and conventional reels also optimizes the support distance and pinion gear thickness to achieve high support rigidity so that anglers can actively wind under heavy loads without compromising gear strength.

The MGL Spool III thoroughly pursues low inertia and features a narrow-shape design with a width of 19 mm that reduces inertia by about 15% compared to the second-generation MGL Spool with a width of 22 mm. But even with a reduced width, the MGL Spool III maintains line capacity with an outer diameter of 34 mm. The benefit of MGL Spool III: unparalleled casting performance.

CoreSolid Body integrates the B-Side Plate, levelwind guard and frame into a solid one-piece construction. This delivers an unprecedented feeling of rigidity and sensitivity, and is the first design of this type in a low-profile baitcast reel.

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'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.

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.
