Shimano's proprietary Spiral X Core technology powers Poison Adrena B, enhancing Shimano's traditional Spiral X carbon tape construction by utilizing Toray Nanoalloy® technology to provide up to 10% more torsional rigidity and up to 15% more compressional rigidity than rods built with standard Spiral X technology. Combined with a redesigned Full Monocoque Handle and proprietary CI4+ reel seat, the Poison Adrena series provides unparalleled lightness and durability while delivering heightened sensitivity with increased transmission of lure action and bites. Adorned by a guide train comprised of Shimano X-Guide and Fuji SiC guides to balance Poison Adrena perfectly, these premium guides reduce overall rod weight while increasing casting distance and accuracy.
