To allow anglers to perform at their best, Shimano offers two distinct spinning reel concepts, CORESOLID and MAGNUMLITE Series.
This section introduces both concepts in detail.
At the heart of these concepts lies the rotor.
The rotor is the key component that distinguishes the CORESOLID and MAGNUMLITE series. The rotor plays a critical role in the retrieval process by winding line onto the spool.
In the CORESOLID Series, the rotor is made from from high-inertia materials, such as metal or high-strength resin, which maintains momentum once force is applied. This design provides a solid, powerful winding feel.
In contrast, the MAGNUMLITE series features a rotor made from low-inertia materials, like Shimano’s C14+ carbon fibre reinforced resin.
The Shimano CORESOLID Series
With Stella as Shimano’s flagship model, the CORESOLID Series represents the foundation of Shimano’s smooth and refined spinning reel performance.
As previously noted, the CORESOLID Series utilises rotors crafted from metal or high-strength resin, providing exceptional rigidity and moderate rotational inertia. This results in a silky, weighty rotation feel.
The inertia allows the rotor to sustain its momentum once in motion, reducing angler fatigue during long, consistent retrieves.
Unique Advantage: Metal Rotor
In the CORESOLID Series, STELLA and TWINPOWER utilise metal rotors known for their high rigidity and moderate inertia.
This construction delivers a smooth, dampened rotation feel with a strong sense of control. The rigid rotor design also minimises flex and distortion under heavy loads, enhancing hook-setting power and ensuring consistent drag performance.
The Shimano MAGNUMLITE Series
The MAGNUMLITE Series is engineered for exceptional lightness and ultra-responsive reeling. As previously mentioned, it features low-inertia MGL rotors crafted from CI4+ carbon fibre reinforced resin, significantly reducing overall weight and boosting agility and sensitivity.
By minimising rotor inertia, the reel reacts instantly to even the lightest movement, allowing anglers to detect subtle lure vibrations and changes in the water more easily.
The heightened sensitivity helps anticipate bites, making the MAGNUMLITE Series ideal for a wide range of fishing styles.
Rotor Designed for Unmatched Rotational Lightness
The MGL Rotor’s asymmetrical design provides exceptional rotational lightness and enhanced handling, making it easier to detect subtle changes in the line. Its low-inertia construction improves start-and-stop responsiveness, enabling anglers to react instantly to sudden bite opportunities. This precise control over lure movement, action sharpness, and retrieve consistency empowers anglers to confidently entice fish to strike.

Our goal, effortless reeling.
Shimano's reel design concept aims for “eternally smooth reeling.” The result is HAGANE. Shimano honed its proprietary metal processing technologies with precision cold-forging technology and refined them over many years to develop reels that only Shimano could deliver.
Reduced line release resistance for an optimised casting experience.
The line is meticulously wound around the spool, ensuring a tight and organized configuration that greatly minimizes line release resistance. This refinement enhances the casting experience, enables smooth line retrieval, and heightens sensitivity during the fall, allowing for more precise control and responsiveness.
Experience an exceptional gear system designed for high performance and unwavering durability.
INFINITYXROSS distributes the load across a wider area of the gear tooth surface, resulting in exceptional durability.
Seize control with powerful reeling.
When the rod bends powerfully and you grip the handle knob to stop the target's escape, the reel's design ensures smooth power transfer, giving you the upper hand in the fight.
Shimano's INFINITYDRIVE eliminates those frustrating moments, ensuring powerful reeling even under high load. With this technology, you'll be able to land big fish that once seemed impossible to catch.
