CI4 is a Shimano original material reinforced with carbon fiber that is lighter and has a higher strength than conventional resin material. CI4+ is an advanced version of the original CI4 material and is 2.5x more rigid than its predecessor. While improving lightness and rigidity, reel bodies, rotors and reel seats built with CI4+ are further reduced in size and weight.

Carbon Monocoque grip is a carbon-molded grip that is lightweight with high sensitivity, transferring even the smallest vibration to an angler’s hand. The Carbon Monocoque Grip increases sensitivity by 30% compared to traditional rod handles and utilizes a hollow structure that eliminates unnecessary parts of the rear grip to improve weight reduction and vibration transmission.

Hi-Power X construction uses diagonally-wrapped carbon tape to form an array of "X" shapes on the rod blank's outermost layer. The width of the tape, its winding angle and the part of the rod being wrapped are fine-tuned according to the target fish species. This manufacturing process allows Shimano to adjust these wraps during construction for precise actions, enhanced overall strength and added twist resistance. In short, Hi-Power X construction delivers sharp and crisp rod control for the angler.

The flexible solid tip is reinforced with ultra fine carbon tape. This reinforcement suppresses power loss due to twisting without hindering the delicate bending of the solid tip. Cast accuracy, operability, and sensitivity has been dramatically enhanced by the application of HI-POWER X Solid.

SHIMANO’s TAFTEC α is a unique solid tip that realizes flexibility and delicate bending without reducing the diameter of the tip or its strength. The TAFTEC α tip is used throughout the Shimano rod range where sensitivity is an important requirement of the rods.
