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%.

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.

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.

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.

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.
