Shimano brand reel design based on cold forged gearing. Such a gear is strong and offers greater resistance to overload than die-cast gears. The overall result is increased durability of the reel.

CI4+ is an improved version of the original CI4. This material, with its exceptional technological advances, is characterised by a stiffness that exceeds by as much as 2.5 times that of CI4, and can only be found in Shimano's most expensive, extremely lightweight reels. With CI4+, it is possible to achieve significant towing power while maintaining reliability and no risk of deformation of parts.

X-SHIP technology is an innovative system that significantly improves the efficiency and power of the reel's gears. Its main purpose is to eliminate twist and flex in the rotor. As a result, even during heavy loads, the crank turns smoothly and with ease.

SA-RB technology from Shimano is an advanced bearing system that is an evolution of the well-known and highly regarded A-RB solution. The most important feature of SA-RB bearings is their outstanding corrosion resistance, making them the ideal choice for extreme conditions such as offshore fishing or intensive use in variable weather conditions.

Cross Carbon Drag technology is a brake system that uses carbon fibre pads. It provides greater flexibility in settings and smoother operation during loading.

The I-DC4 technology analyses the changes in the situation from the moment of casting until the lure reaches the designated spot, reading the rotation of the spool and making small adjustments to the brake.

Super Free Spool technology is an advanced system that effectively eliminates friction occurring at the edges. This allows the reel to run smoother and more efficiently, increasing performance and reliability.
