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 X guide was born from the viewpoint to bring out the potential of blanks to the full. Supporting the guide rings of the tip part is a one-piece structure frame molded with the latest material by 3D technology. Its beautiful shape combines strength with the calculated inclination angle and three-dimensional structure to suppress line entanglement. The tip guides are light and small. In the butt part we have the Aero Titanium X guide which contributes to casting feeling and casting distance. X guide is Shimano's original high performance guide which fused lightness, trouble less, casting performance to higher dimensions.

The Full Carbon Monocoque Grip is the evolution of the Carbon Monocoque Grip. A high-sensitivity grip made entirely of hollow carbon construction eliminates the use of EVA. This results in a very lightweight construction and enhanced sensitivity. Compared to the normal Carbon Monocoque Grip — which has 30% greater sensitivity over traditional handles — the sensitivity increases by another 28% with the Full Monocoque Grip.

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.

The Carbon Shell Grip is a next-generation grip structure made out of a hollow carbon structure. It contributes to the transmittance of vibrations to the hand. A lightweight, high-sensitivity grip that defies conventional wisdom.

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.

MUSCLE CARBON is a high-performance material that reduces the gap between fibers by bundling carbon fibers more dense than normal carbon material, and this dense structure reduces the amount of resin needed to fill the gaps in between the fibers.

Ultimate Blank Design is a design technology that carefully selects the target material from over 100 different types and places it in place in each section of the tip, belly, and butt of a blank. All material is in it's right place to realize the ideal rod action condition. It is a new design structure that realizes weight reduction while maintaining strength and power.

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. The use of CI4+ for the reel seat increases sensitivity and reduces weight while also delivering remarkable rigidity for perfect reel fixation and better rod efficiency.
