The Ultegra FD spinning reel delivers reliable performance with powerful winding and durable CoreSolid construction, incorporating flagship Shimano technologies at an accessible price. The redesigned internal structure of Ultegra FD features InfinityXross technology, which extends the cold-pressed HAGANE gear tooth surface, distributing force load over a wider area to prevent stress points and reduce wear, enhancing the reel's longevity. InfinityDrive technology offers smooth, effortless winding — even under heavy load — by reducing friction between the spool shaft and pinion gear for improved efficiency. The flexible polymer Anti-Twist Fin ensures even line lay on the spool and minimizes the occurrence of wind knots. For anglers who fish in both fresh and saltwater, the Ultegra FD features Shimano's X-Protect technology, which aids in preventing water from entering internal structures and helps reduce the risk of corrosion. With a blend of innovative features and lasting durability, the Ultegra FD is a dependable, performance-forward choice for all anglers at an exceptional value.

Features:

• HAGANE: 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.
• HAGANE Gare: 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.
• MicroModule Gear II: 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 Spinning: 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.
• Infinity Drive: The Infinity Drive structure is an advanced structure that creates 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.
• SilentDrive: 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.
• Anti-Twist Fin: Shimano designed the Anti-Twist Fin for enhanced line management resulting in more effective fishing. 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.
• X PROTECT: 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: 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.
• Long Stroke Spool: 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+ Spinning: 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.
• S A-RB Baitcasting: 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.
