Shimano Twinpower XD FB Spinning Reels

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

With amazing strength and durability, the HAGANE Gear is at the very heart of most Shimano reels. Shimano, through the application of state-of-the-art technologies, gives anglers the long-lasting smoothness and pleasure that is felt when anglers first use a reel, over and over again. No cutting work is applied to the teeth of the drive gear during fabrication, instead the entire surface is calculated in minute detail by special 3D-design and then formed by Shimano's cold-forging technology. The result is assured resilience. HAGANE Gear is the fruit of Shimano's inexhaustible pursuit for durability — the strength and power of forged metal continues to represent the fundamental concept of Shimano reels.

Shimano's exclusive manufacturing technology further advances MicroModule Gear II with a state-of-the-art gear-tooth surface design. The surfaces of the drive gear and pinion gear have been analyzed and updated from the ground up in Shimano’s pursuit of perfection to further improve the smooth gear feeling and reducing sound.

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 increased support allows the gears to stay in the same position under the heaviest loads. X-Ship technology also eliminates the friction between the spool shaft and gear to further benefit anglers with enhanced casting performance and casting distance of lighter lures.

InfinityLoop technology delivers exceptional casting performance by drastically reducing friction on the line leaving the spool. Advancements in the internal structure and design extend the spool's oscillation to enable the spool to move up and down at an extremely low speed. This technology creates a precise winding pattern with less overlap that significantly reduces friction as the line leaves the spool during a cast. The result is smooth and exceptional casting performance, especially of light lures.

Advancements in manufacturing technology and gear tooth design improve the surface contact and meshing between the drive gear and pinion gear. This revolutionary design efficiently distributes the load placed on the gear tooth surface across a wider area to prevent damage from stress points while significantly improving overall gear durability.

The Infinity Drive structure is a more advanced version of the conventional X-SHIP structure that created exceptionally light winding. The main shaft, which had previously been supported by the pinion gear, is now supported by a new and unique low-friction bushing that significantly decreases frictional resistance. In addition, the main shaft has undergone a proprietary surface treatment and special processing to drastically reduce rotational torque, constructing a reel that can actively wind even under heavy loads.

Constructed to enhance overall durability, this revolutionary drag washer incorporates cutting-edge materials woven in a unique pattern compared to conventional drag washers. Without sacrificing a smooth drag feel, this new material is greater than 10x more durable for improved drag performance.

SilentDrive technology benefits from a total redesign of all functional parts focused on the drive gear, worm shaft and other parts. The goal: remove unnecessary noise and vibration. In doing so, the overall tolerances are improved to a micron level, ultimately creating an overall quieter and smoother reel operation.

The Magnumlite Rotor is an ultra-light improved rotor made from Ci4+ material. This rotor is completely redesigned. The profile of the rotor is made asymmetrical and the bail arm mechanism, which is usually situated on the same side as the line roller, has been moved to the opposite side. Both changes improve the balance and decrease the overall weight. The rotor rigidity at the line roller side has been improved and reduces the deflection under maximum pressure by up to 30%. The Magnumlite Rotor is 25% lighter, offering better balance and requiring 22% less inertia, making it easier to start and stop your retrieve for an overall smoother feel. To reduce weight further, Magnumlite rotors have openings on the side. The Ci4+ material is so strong that very little material is needed to retain the required amount of strength in the rotor.

The flexible polymer fin is installed near the line roller. This maintains line tension to reduce sagging and prevents the line from falling off the bottom of the spool or wrapping around the spool in an uneven manner.

For medium and small general-purpose spinning reels, which require lighter spinning, we focused on a non-contact structure that does not compromise the lightness of the spinning. In addition to conventional water-repellent treatment, a labyrinth structure that suppresses water penetration is combined to achieve high water-resistant performance despite the non-contact nature of the structure. It is used in the stopper bearing section and line roller section.

G-Free Body technology has been developed to shift the reel's center of gravity closer to the rod. By moving the center of gravity closer to the angler’s hand, the G-Free Body helps to reduce fatigue and enhance casting comfort.

The Long Stroke Spool has a longer stroke compared to conventional spool designs. This ultimately produces a smoother line lay during retrieval and translates into increased casting distance for anglers.

Ci4+ is a composite material with very special characteristics. This highly technical carbon material maintains 2.5 times more rigidity than a normal CI4. The material is native to Shimano and extremely lightweight. Because Ci4+ does not contain any metal, it is not affected by corrosion, making it suitable for saltwater use. Ci4+ parts are lighter and stronger than any other composite material SHIMANO uses in their products. Reels with a Ci4+ body are lightweight, very strong and ideal when continuous casting is required. Ci4+ is also ideal for saltwater inshore situations where corrosion may be a problem over time.

By strengthening the spool support of the main shaft, the play and fluctuation of the spool during drag operation are suppressed. The Rigid Support Drag allows smooth and consistent drag delivery, even under high load.

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 the rotation of the bearing.

One-Piece Bail allows the line to travel unimpeded to the line roller. The seamless design reduces friction and decreases the chance of tangles or the line catching on the bail arm.
