CI4+ Body: This material is an advanced version of the original CI4. This highly technical carbon material maintains 2.5 times more rigidity than CI4. While improving lightness and rigidity, the body is further reduced in size and weight.
MGL Rotor: The new design of the MagnumLite Rotor produces unprecedented light rotation. The rotor profile is now asymmetrical. The bail arm mechanism, which was previously situation on the same side as the line roller, has been moved to the opposite side. This improves balance and combined with a lightweight line roller, titanium bail and optimum arrangement of rotor thickness, a 14% reduction in rotational inertia has been achieved increasing sensitivity to unreached levels
Hagane Gear: With amazing strength and durability, the HAGANE Gear is at the very heart of the reel. Shimano, through the application of state-of-the-art technologies, gives you the long-lasting smoothness and pleasure that you feel when you first use a reel, over and over again. No cutting work is applied to the teeth of the drive gear. Instead the entire surface is calculated in minute detail by special 3D design and then formed by Shimano’s cold forging technology
MIcroModule Gear II: State-of-the-art, gear tooth surface design and MicroModule Gear II, are further advanced through Shimano’s exclusive manufacturing technology. The surfaces of the drive gear and pinion gear have been analyzed and updated from the ground up in pursuit of perfection. Further improving smooth gear feeling and reducing sound.
Silent Drive: From the fundamental, whole body design to the most intricate parts of the drive train, including the drive gear, wormshaft, wormshaft pin and wormshaft gear, every piece has been carefully reviewed, and the smallest clearance gaps and wobbles have been eliminated to the highest tolerances.
