The 2021 TwinPower SW series is stronger and more durable than ever, designed to challenge the impossible across six models. Featuring Infinity Drive and Heat Sink Drag, it reduces handle rotation torque and prevents heat transfer. The X-Protect seal and labyrinth structure repel water intrusion, while the striking silver and blue cosmetics make a statement. Engineered and made in Japan to the highest standards, the TwinPower SW is perfect for the world’s hardest fighting saltwater species.


Product Features:

- Infinity Drive for Light and Powerful Winding

- Heatsink Drag Upgrade for Superior Heat Resistance Under Extreme Pressure

- Ipx8 Waterproof Performance Via X-Protect And X-Shield

- Cold Forged Hagane Gears for Extreme Durability

- Highly Rigid Aluminium Hagane Body

- 10 Year Warranty

Product Technologies:

Hagane Gear

The HAGANE Drive Gear is produced by Shimano's cold forging technology. without the need for additional machining. This delivers a long-lasting smoothness, strength, lightness and power at the very heart of the reel. Traditional diecast, machined gears are less durable under heavy loads.

Hagane Body

The HAGANE Body is produced from high rigidity aluminium or magnesium. This creates stiffness and impact resistance, while at the same time eliminating flexing of the body. The result is a rock-solid housing and support for the moving internal gearing and greater efficiency throughout the reel.

Silent Drive

Removed 'clicking' sound and 'handle play' and overall improved smooth reeling.

Infinity Drive

Developed to provide more powerful and light winding through bearings supporting the pinion gear. By doing so the rotational resistance of the reel has been decreased up to 60%.

Heatsink Drag

Upgraded drag with superior heat resistance through a Heat Sink Panel and Insulation Sheet which blocks heat transfer to the spool and ensures drag performance.

ARC Spool

Shimano ARC Spool is a patented spool design with an angled spool lip. This design enables the line to leave the spool with less friction and in smaller coils resulting in longer more accurate casts. ARC spools are proven to reduce backlash and wind knots when using braid.

E.I. Surface Treatment

E.I Surface treatment doubles the durability of the spool surface and gives less wear out by eliminating oxidation.

One Piece Bail

The one-piece bail wire has no gap for line to snag on during normal operation. Made of Stainless Steel, it reduces friction and allows the line to get onto the line roller quicker.


Shimano S ARB bearings are high corrosion resistant ARB ball bearings with an extra shield for improved protection against sand, salt or dust.


The contact type triplelip structure is introduced to the roller clutch, the pivotal point concerning water resistance. In this structure, the first lip prevents water from entering through the space between the rotor and the body. In addition, the special grease between the second and third lip where it contacts the rotor collar located at the upper part of the roller clutch not only resists water from entering but also minimizes friction resistance. Without jeopardizing the 'silky smooth rotation capacity', the vital feature of STELLA SW, exceptional water resistance. has been achieved to withstand the crashing and splashing of waves and spray.


By providing dependable sealing structures and gaskets at necessary points, including the reel body and lid joint and the contact point of the spool and drag knob, possible water ingress is blocked. This double protection provides high reliability and durability to the STELLA SW when used in extreme saltwater conditions.


XShip is a combination of features that work together to create much greater efficiency. By positioning the pinion gear close to the center line of the large diameter drive gear, more power is transferred from the handle to the rotor. The pinion gear is also supported by two Shimano ARB roller bearings. This creates more stability.

Xtough Drag

The drag system of the new STELLA SW has advanced enormously in terms of toughness, smoothness, and performance. The basic drag performance has been extensively reviewed and each of the metal and carbon drag washers show excellent heat resistance and durability. Through an in-depth study of the thickness and frictional force of each component within the drag system, the best combinations for optimum performance parameters have been found for each model and size. Further, the structure supporting the middle surface of the spool, from both the top and bottom, efficiently disperses the load, securing a smooth and stable drag force. Inside the drag knob, a coiled wave spring is mounted to allow anglers to make fine adjustment, even when under a heavy load.

Cross Carbon Drag

This carbon drag material provides a wider range of drag settings, along with the smoothest Shimano drag performance ever.
