Shimano 25 Ultegra FD 4000XG Spinning Reel

Description

The Ultegra has earned a strong reputation among anglers for delivering exceptional rotational performance and durability that exceed expectations for its price range. Designed within the CORESOLID series, it offers smooth and stable winding, making it ideal for techniques that require continuous retrieval with high-resistance lures, such as vibration plugs.

Now upgraded with INFINITYXROSS, INFINITYDRIVE, and ANTITWISTFIN, the Ultegra provides enhanced power, efficiency, and line management. Whether you're a beginner or an experienced angler, this reel offers the performance and reliability to meet your fishing demands.

Features & Technology:

• HAGANE Design

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 Gear

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 enjoyment that is felt when anglers first use a reel, over and over again.

• MICROMODULE II

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

• INFINITYXROSS

INFINITYXROSS provides superior gear durability through industry-leading design and cutting-edge manufacturing technology. Advancements in the 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.

• INFINITYDRIVE

INFINITYDRIVE is a new main shaft supporting structure that improves winding torque and allows for incredibly smooth and light rotation.

• SILENT DRIVE

The basic design of the entire body and drive-related parts were reviewed one by one to reduce minute rattles, gaps, and shaking between parts down to the smallest detail. It provides smooth and quiet reel rotation.

• ANTI-TWIST FIN

Elastic fins are installed in close proximity to the line roller section. By suppressing line slack, the fins reduce the phenomenon of line dropping out of the lower part of the spool and line wrapping around the spool while the line is still twisted.

• 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.

• AR-C SPOOL

The spool has a special spool ring shape. This creates a rectifying effect on the line and realizes both suppression of line trouble and long casting performance.

• LONG STROKE SPOOL

The LONG STROKE SPOOL has a longer stroke compared to conventional spool designs. It contributes to improved casting feel and distance.

• CI4+

CI4 is a resin 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.The rigidity and durability have been greatly improved from original CI4 material while maintaining the lightness of the material, making it possible to reduce the size and weight of the reel.

• CROSS CARBON DRAG

 The CROSS CARBON DRAG provides the smooth drag release and the  durability.

• SA-RB

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

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.
