Spiral X Core is Shimano's newest and most advanced blank construction technology. By integrating Spiral X carbon tape construction with Toray Nanoalloy® technology, Spiral X Core constructed blanks benefit from up to 10% more torsional rigidity and up to 15% more compressional rigidity than rods built with Spiral X. Shimano is unique to the market by applying by high-strength carbon tape with this unique and patented Spiral X construction.

The new X Seat Extreme is designed to satifsy 'ease of holding' and unstressed fishing, even during a long day and under heavy power loads. The X Seat Extreme gun grip eliminates complaints often heard from jigging or bottom anglers, like fatigue in the hand due to pressure from the reel seat and fatigue in the wrist due to the angle of the wrist needed to hold the rod. The X Seat Extreme is designed to increase the contact surface of the seat in the palm of the hand by utilizing an enlarged grip so the angler can hold it firmly and stable it in the whole palm of the hand. With conventional reel seats, it was inevitable to endure a load to the wrist and the arm because of the angle of the wrist at the time of reeling or fighting fish, especially under heavy power loads. However, the X Seat Extreme Extreme gun grip succeeded in keeping the angle of the wrist close to straight resulting in less burden, by designing the right and left seat exclusively for this commitment. The X Seat Extreme made it possible to reduce hand trembling and fatigue (-45%) regardless of the size or load during dropping, reeling and hooking. Moreover, since it is possible to grasp the enlarged grip firmly without gaps, the sense of stability (+30% compared to SHIMANO previous reel seats) especially during the fight with large size fish is drastically increased.

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.

Shimano’s Nanopitch manufacturing method enables fine-pitch and high-precision wrapping of the molding tape during the blank baking process. Nanopitch technology tightens the tape to the extreme and provides uniform pressure, increasing the circularity of the rod and ultimately improving overall rod strength.

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.
