October 3, 2025The Storm EquinoX Solid is the high-performance answer for bowlers demanding more hook and a bolder motion on heavy oil. While maintaining the core technology that made the line a favorite, the Solid version is built to stand out, offering a dramatically aggressive shape that goes toe-to-toe with the strongest balls on the market.
Features
A2S SOLID REACTIVE COVERSTOCK: The next evolution of Storm’s Adhesion System Technology, the A2S coverstock pushes the limits of oil absorption. It delivers fierce mid-lane traction while maintaining a sharp, angular response—a rare and dynamic combination for a textured solid ball.
SOLARION + A.I. CORE: The revolutionary tri-cylindrical Solarion Core returns to provide a decisive motion at the breakpoint. The unique three-cylinder design optimizes energy transfer: a large cylinder for fast revving, a top cylinder for drilling versatility, and a weighted base for increased torque and continuation.
AMPLIFIED INERTIA (A.I.) TECHNOLOGY: Integrated into the core design, A.I. technology enhances hitting power and pin carry, ensuring that the ball retains maximum energy as it drives through the pocket.
