With 80% of leagues and weekend tournaments played on oil patterns between 39 and 44 feet (Doug Dukes, VP of Sales, Kegel), the Storm EquinoX is purpose-built for league bowlers. Designed for these conditions, it delivers the signature backend motion Storm is known for—combining powerful reaction with consistent performance. The EquinoX is the ideal choice for bowlers looking to dominate their league nights and weekend tournaments with confidence and precision.

The Solarion A.I. Core is designed with three distinct cylinders that optimize motion. The largest cylinder lowers the RG for fast revving and a tumbling front-lane read. A top cylinder enhances drilling versatility, while the lightweight base increases torque and continuation. This unique design creates the classic skid-flip reaction Storm is known for, with added control and power.

The all-new A1S Pearl Reactive coverstock debuts Storm’s Adhesion System technology, setting a new standard in lane grip and responsiveness. Engineered for exceptional tackiness, this innovative coverstock pairs perfectly with the Power Edge Polish, a finish designed to create effortless length and a sharp, controlled move at the breakpoint. Together, they deliver the ball motion bowlers crave, making the EquinoX a standout choice for tackling league conditions and beyond.
