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.

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 SOFTUBE TOP provides the sensitivity of an ultra fine solid carbon tip with the lightness of a hollow/tubular construction. SOFTUBE TOP construction can be found on rods where sensitivity and finesse are both important requirements. The smooth, seamless action of SOFTUBE TOP offers the angler an unrivalled experience for bite detection and fish-playing performance.

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.
