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. 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.

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. 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.
