At the heart of the Bionic is the Torsion™ A.I. Core, an evolution of the Element Max™ Core. Its symmetrical, rotated stacked ellipse design maintains low RG stability while delivering a smooth, controllable arc. The center-heavy mass and flip block work together to create the unmistakable Storm motion off the end of the lane, giving bowlers confidence in every shot.
