Major Changes in the "25 Twin Power XD"
Let's start by examining the evolution and changes from the 21 Twin Power XD to the 25 Twin Power XD.
Appearance
First, a look at the visual differences.
The 2021 model featured a navy blue color, but the 2025 model has shifted to a black (gray) based color scheme.
Shimano 2021 Twin Power XD
Lineage
Looking at models from the same generation, the 25 Twin Power XD's rotor visually resembles that of the 23 Vanquish, while its body looks similar to the 24 Twin Power (see image below).
In fact, checking Shimano's support site reveals that the relevant parts are identical in composition (although they are not necessarily interchangeable, so caution is advised).
Material-wise, this is confirmed as well: the rotor material on the 25 Twin Power XD is the same CI4+ as the 23 Vanquish, and the body material is the same aluminum and CI4+ combination as the 24 Twin Power.
Furthermore, these three models share almost the same drivetrain components, including the main drive gear (except for the pinion gear, which differs only on the 23 Vanquish).
The 23 Vanquish, 24 Twin Power, and 25 Twin Power XD form a trio of high-class reels.
The 25 Twin Power XD is a hybrid, combining the lightweight, low-inertia rotor of the 23 Vanquish with the highly rigid body of the 24 Twin Power.
Additional Note:
Upon close inspection, the body design of these three reels—including the 23 Vanquish—is the same. However, the 23 Vanquish uses magnesium instead of aluminum to prioritize lightness.
Functional Changes
The 25 Twin Power XD features six major functional upgrades:
- New X-Protect on the line roller for tripled durability
- Infinity Cross for doubled gear durability
- Infinity Drive for powerful winding under high load
- Infinity Loop for ultra-dense winding improving casting distance and drag performance
- Anti-Twist Fin to reduce line troubles
- DuraCross drag washers with 10 times wear resistance
Among these, the most notable is the first: New X-Protect.
This feature is introduced for the first time in the 25 Twin Power XD.
The other five upgrades (2–6) are shared with the 23 Vanquish and 24 Twin Power.
Additional points:
- The reel's weight remains unchanged
- Manufacturer’s suggested retail price increased by approximately 7,500 to 8,800 yen
Let's examine each upgrade in detail.
1) Line Roller Durability Tripled with "New X-Protect"
The 25 Twin Power XD introduces for the first time in the entire series the new waterproofing technology called New X-Protect on the line roller.
X-Protect is a waterproof structure combining hydrophobic treatment and a labyrinth structure to prevent seawater intrusion.
In the New X-Protect, the traditional labyrinth structure has been improved into a new labyrinth structure.
| Traditional X-Protect | New X-Protect |
|---|---|
| Special hydrophobic grease + labyrinth structure | Special hydrophobic grease + new labyrinth structure |
2) Gear Durability Doubled with "Infinity Cross"
The gears are the most critical part of a reel.
They endure significant load, and wear on the gear teeth often causes roughness or malfunction.
Infinity Cross is a gear designed to significantly increase durability by enlarging the contact area of the gear teeth.
Comparing the old and new gear teeth shapes, the teeth are slightly shallower but much longer.
Thanks to Infinity Cross, gear durability is approximately doubled compared to the previous design.
3) Powerful Winding Under High Load with "Infinity Drive"
During a fight, if you can't reel in against the fish’s pull, the fish may escape by hiding in rocks or thrashing about.
Infinity Drive ensures smooth and powerful winding by making the spool shaft's vertical movement smoother.
Specifically, it works by:
- Supporting the main shaft (which moves the spool up and down) with a special low-friction bushing
- Applying special surface treatments and processing to the main shaft itself
Because the main shaft moves more smoothly, even under high load the spool moves up and down without resistance, enabling more powerful reeling.
Technical Note: "X-SHIP" and "Infinity Cross"
A spinning reel converts the handle rotation into two motions: rotor rotation and spool vertical movement.
- X-SHIP smoothes rotor rotation
- Infinity Cross smoothes spool vertical movement
Together, they improve drivetrain smoothness, making winding easier under high load.
4) Ultra-Dense Spooling for Increased Casting Distance and Drag Performance with "Infinity Loop"
Improved casting distance can directly lead to better catch rates.
Infinity Loop slows the spool’s vertical oscillation during line winding, resulting in an ultra-dense spool of line.
Denser spooling substantially reduces line release resistance.
This smooth line release offers three advantages:
- Increased casting distance
- Stable fall speed after water entry, making bites easier to detect
- More stable drag performance
Technical Note: Features Unique to Shimano’s High-Class Reels
Mid-class reels like the Ulttgra, Stradic, and Vanford differ from high-class reels like Twin Power, Twin Power XD, and Vanquish in three major features—one of which is Infinity Loop. The others are Rigid Support Drag and metal & CI4+ bodies.
5) Anti-Twist Fin Reduces Line Trouble
Because Infinity Loop dramatically reduces line release resistance, there is concern that line may unintentionally come off the spool, causing trouble.
Shimano’s countermeasure is the Anti-Twist Fin, an elastic fin located beneath the line roller.
This fin prevents line from falling off (known as "line drop"), significantly reducing line troubles.
6) DuraCross Drag Washers with 10x Wear Resistance
DuraCross is a drag washer that maintains smooth drag operation while increasing wear resistance more than 10 times by changing the fiber structure.
Shimano’s durability tests clearly show that DuraCross washers outperform traditional felt washers by a large margin.
Technical Note: Drag Washer Materials
Usually, carbon drag washers offer high durability but poorer initial slip. Felt washers provide smooth slip but wear out quickly. DuraCross achieves improved durability while maintaining the smooth slip of felt by cross-weaving the fibers.
Minor Update
The gear ratio on HG models has been slightly lowered:
| Model | 21 Twin Power XD | 25 Twin Power XD |
|---|---|---|
| C3000HG Gear Ratio | 6.0 | 5.8 |
| 4000HG Gear Ratio | 5.8 | 5.7 |
This improves the handling expected from the Twin Power XD series.
Summary of 25 Twin Power XD Updates
- Line roller durability tripled (New X-Protect)
- Gear durability doubled (Infinity Cross)
- Increased winding power under high load (Infinity Drive)
- Improved casting distance and drag stability (Infinity Loop)
- Reduced line troubles (Anti-Twist Fin)
- Drag washer wear resistance increased tenfold (DuraCross)
With so many upgrades, if you are deciding between old and new Twin Power XD, the 25 Twin Power XD is highly recommended—unless the 21 Twin Power XD is available at a bargain price.

The Position of Twin Power XD in Shimano's Lineup
Shimano’s general-purpose small spinning reels are divided into two series based on rotor type:
- Magnum Light Series: Features low-inertia rotors ideal for finesse-style fishing
- Core Solid Series: Features high-inertia rotors ideal for power-style fishing
The Twin Power XD belongs to the Magnum Light Series and is a high-class model just below the Vanquish.
Despite the hierarchy, the 25 Twin Power XD inherits the lightweight, low-inertia rotor from the 23 Vanquish and the highly rigid body from the 24 Twin Power. The internal drivetrain, including the drive gear, is shared among these three, making them a "trio" of high-class reels.
For reference:
- 23 Vanquish, 25 Twin Power XD, and 24 Twin Power are the top-level "brothers"
- 24 Vanford, 23 Stradic, and 25 Altégra form the mid-class "brothers"
Additional Note: Shimano’s General-Purpose Spinning Reel Complexity
Shimano’s lineup also includes entry-level models like Nasci, Sahara, Sedona, Nexave, Sienna, FX, plus specialized reels. Though complex, understanding the sibling relationships simplifies the landscape.
Comparing the 25 Twin Power XD with Other Shimano Reels
Commonly compared models near the same price:
- 23 Vanquish: Top of the Magnum Light Series
- 25 Twin Power XD: High-class Magnum Light Series (this model)

Ball Bearing Locations
Ball bearings improve rotation smoothness and generate differences in reel feel.
| Model | Ball Bearing Locations and Effects |
|---|---|
| 24 Twin Power (9 BB) | - Pinion Gear (2) - better winding feel - Drive Gear (2) - Line Roller (1) - reduces line trouble - Handle Knob (2) - Spool Up/Down (2) - smooth drag |
| 25 Twin Power XD (10 BB) | Adds 1 BB on Rotor Nut for improved winding feel under load |
| 23 Vanquish (11 BB) | Adds 1 BB on Worm Shaft Gear for smoother spool vertical movement |
The Rigid Support Drag (spool up/down ball bearings) on the 24 Twin Power smooths drag operation—a feature distinguishing mid- from high-class reels.
Body and Rotor Materials
The 25 Twin Power XD inherits the body from the 24 Twin Power, made from a composite of aluminum and CI4+ (carbon fiber reinforced plastic). The reel foot, which requires high rigidity, is metal.
The rotor is inherited from the 23 Vanquish, made of lightweight CI4+ for low inertia, placing the 25 Twin Power XD in the Magnum Light Rotor category.
Magnum Light Rotor Advantages
A lighter rotor has lower inertia, making it easier to start and stop rotation, ideal for finesse fishing.
The 25 Twin Power XD and other high-end models feature an asymmetrical rotor shape to further reduce inertia by 28% and weight by 36% compared to Core Solid rotors.
Gear System
The drive gear, pinion gear, and worm shaft parts of the 25 Twin Power XD are nearly identical to those in the 23 Vanquish and 24 Twin Power (except for the 23 Vanquish’s pinion gear).
Handle Material
The 25 Twin Power XD uses an aluminum handle for enhanced durability, consistent with its 24 Twin Power body.
The 23 Vanquish focuses on weight reduction with a CI4+ handle (except for the C5000 size which uses aluminum).
Handle Knob Types
All 25 Twin Power XD models feature round handle knobs. The 23 Vanquish (C5000XG) and 24 Twin Power (4000PG and C5000XG) also use round knobs.
Spool Ring Material and Coating
The spool ring is a vulnerable part prone to scratches, which can reduce casting distance and cause line breaks.
The 25 Twin Power XD uses stainless steel spool rings with SW Barrier Coat, the highest-grade setup, similar to the 24 Twin Power and 22 Stella.
In contrast, the 23 Vanquish uses aluminum spool rings with a high-durability hard coating, prioritizing lightness.
Summary: Who is the 25 Twin Power XD For?
| Model | Features | Ball Bearings |
|---|---|---|
| 23 Vanquish | Lightweight - Magnesium + CI4+ Body - CI4+ Rotor & Handle - Aluminum Spool Ring |
11 |
| 25 Twin Power XD | Lightweight + Rigid - Aluminum + CI4+ Body - CI4+ Rotor - Aluminum Handle - Stainless Steel Spool Ring |
10 |
| 24 Twin Power | Rigid - Aluminum + CI4+ Body - Metal Rotor - Aluminum Handle - Stainless Steel Spool Ring |

The 25 Twin Power XD blends the 23 Vanquish rotor with the 24 Twin Power body, offering a hybrid that balances rigidity and lightweight sensitivity.
It is especially suited for:
- Light shore jigging with repeated jerking and pauses
- Casting games with sinking pencils and poppers
- Technical seabass fishing
If you want an even lighter reel for extremely delicate fishing or long trips, the 23 Vanquish is optimal.
If your fishing style emphasizes high-speed retrieves or power fights requiring a rigid rotor (e.g., blade jigs, iron vibration baits, flat fish games), the 24 Twin Power or top-tier 22 Stella are better choices.
Extra: What Does "XD" in Twin Power XD Mean?
"XD" stands for extra durability, causing some confusion as it may imply the Twin Power XD is more durable than the Twin Power. In reality, the Twin Power XD holds a middle position among the high-class trio.
Many anglers pursuing light shore jigging or seabass lure fishing find the Twin Power XD perfectly meets their needs.
This concludes the detailed explanation of Shimano's "25 Twin Power XD." For anglers seeking a high-performance, durable, and versatile spinning reel suitable for technical saltwater lure fishing, the 25 Twin Power XD is a compelling choice.
