The Stradic CI4+FB lineup has been developed around Shimano’s G-Free Body, where the oscillating system and worm drive are positioned closer to the stem of the reel. To enhance the feather touch rotation, they also feature a Magnumlite Rotor for greater rotational stability and increased rigidity. Coreprotect, a protective water-repellent coating placed in the roller clutch and line roller, prevents water entering these key areas. Finally, Hagane cold forged gears are smoother, stronger and more durable.
