The totally re-vamped Stradic CI4+FB is a significant improvement over the previous range. Weight has been reduced by 5 grams or more, while other operational features have been improved to further reduce the feel of weight. This model has been developed around Shimanos G-Free Body, where the oscillating system and worm drive have been moved closer to the stem of the reel. This lowers the reels centre of gravity and makes it feel lighter in the hand. To enhance the feeling of lightness and feather touch rotation, the new CI4+FB model comes with the latest Magnumlite rotor. This new rotor design is like no other competing product. The design allows for better rotation stability and increased rigidity while still being lighter than the previous model. The next upgrade was the inclusion of Coreprotect. Coreprotect is a protective water-repellent coating placed in the roller clutch and the line roller to prevent water entering these key areas. Finally, this series comes with Hagane Gear. Shimanos cold forged gears are smoother, stronger and more durable than any others on the market. This gives the reel a much smoother gear transition, but also plenty of pulling power.
