A heavy-oil legend, reborn. The Alpha Crux is back — built to crush modern oil conditions harder than ever. One of the most respected names in Storm history returns with upgraded tech, stronger continuation, and the same unmistakable Crux motion. It blends old-school confidence with modern-day horsepower.

The new GI-26 Solid Reactive cover was engineered for modern oil volumes and longer patterns, digging into heavy conditions without sacrificing predictability. It reads the lane confidently, blends wet/dry, and keeps driving through the deck. At the center is the legendary Catalyst Weight Block — one of Storm's most iconic asyms — combined with A.I. Core Technology for increased energy transfer and relentless continuation. It rolls heavy, and hits even heavier.

Who It's For

• Heavy-oil players — GI-26 solid digs into fresh oil and high-volume conditions.
• Tournament bowlers — a true heavy-oil benchmark for long patterns.
• Rev-dominant players — the Catalyst asym delivers strong, continuous drive through the pins.
