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.

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.

The SCREW LOCK JOINT achieves increased joint strength and ease of detachment by special machining methods. When twisting the rod sections as it is twisted like a screw, the fixing force increases and the sections are more securely locked on the joint section. When unscrewing, the sections can be easily unlocked by twisting in the opposite direction.
