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 ultra-compact precision gear and the elaborate body housing realize a "silky" winding feel that has never been experienced before. SHIMANO's unique gear system that reduces the vibration level to less than half in a vibration comparison with conventional gears (our comparison), and achieves a smooth feeling without sacrificing strength by increasing the number of gear teeth that mesh with each other.

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.

O-ring is placed on the pinion gear inner diameter support of the spool shaft.

Reducing play between both parts contributes to improved handle rotation feel.

The reverse tapered spool corrects the winding shape and reduces spool vibration.

The spool balance after spooling has a significant impact on casting performance. The beginning of the line spooling is particularly important. The newly developed Magnum Light Spool IV features a reverse-tapered shape that is ultra-thin and designed for extremely low inertia. It winds the line evenly and consistently. A well-spooled, balanced spool reduces spool vibration during casting, resulting in improved performance.

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.

Intelligent Digital Control braking system allows anglers to fine-tune their reel to the perfect setting for each line/lure combination, achieving trouble-free and enhanced casting distance. I-DC5 has two sets of dial adjustments. With the inside dial, anglers can select the type of fishing line being used: Nylon Monofilament (N), Fluorocarbon (F) or Braided Line (PE). The outside dial adjustment is based on the lure type: 1. Big Lures (5/8 to 1 oz) with low air resistance, 2. Medium Lures (3/8 to 3/4 oz), 3. Small Lures (1/4 to 7/16 oz) with high air resistance or 4. Finesse Lures (3/16 to 1/4 oz). The final setting is the ‘AUTO’ function (A), letting the onboard DC decide the optimal brake setting. The I-DC5 braking system uses more magnets to assist braking compared to the previous systems. With the addition of a ring magnet, brake force can be applied more evenly and increases the maximum spool revolution by 12% at the start of a cast.

S-Compact Body allows for all-day comfort and improved fishability by making the palming side plate up to 25% smaller than the A-Side plate.

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.

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.
