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 Full Carbon Monocoque Grip is the evolution of the Carbon Monocoque Grip. The complete grip is made of a hollow carbon construction, eliminating the use of EVA. This results in a very lightweight construction which is also more sensitive. Compared to the normal Carbon Monocoque Grip the sensitivity has increased with 128%.

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.
