Through its exclusive lightweight structure, Shimano’s patented Spiral X construction enhances catching power for anglers. Spiral X construction consists of three layers: a middle layer of vertical fibers as well as inner and outer layers, both comprised of carbon tape that tightly winds the blank diagonally in opposite directions. By using this carbon tape in place of a conventional horizontal fiber sheet, Spiral X achieves enhanced compression rigidity and increased torsional rigidity without adding extra weight. This facilitates instant power transmission for precise casting and fish fighting.
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.
Carbon Monocoque grip is a carbon molded grip that is both lightweight with high sensitivity, transferring even the smallest vibration to your hand. Sensitivity increased 30% greater than traditional rod handles. Utilizing a hollow structure that eliminates unnecessary parts of the rear grip improves weight reduction and vibration transmission.
CI4 is a Shimano original material reinforced with carbon fiber. It is lighter and has higher strength than conventional resin material. CI4+ is an advanced version of the original CI4 material. This highly technical material is 2.5 times more rigid than CI4 and is used in Shimano reel seats to increase sensitivity and to reduce weight. Use of CI4+ for the reel seat also delivers remarkable rigidity for perfect reel fixation which results in better rod efficiency.
