Storm Phaze A.I. Bowling Ball — Precision Meets Power in a Pearlized Phaze Upgrade

Think Phaze II—but in pearl form. The new Storm Phaze A.I. takes everything bowlers love about the original and adds a new layer of responsiveness and backend strength, powered by cutting-edge tech and polished to perfection.

At its core is the all-new Velocity A.I. Core, a symmetrical design that fuses low RG with a high differential to deliver fast revs, intense pin action, and a motion that’s both strong and controllable. With a 2.47 RG and .053 differential (15lb), this core is tuned for powerful backend continuation without the unpredictable overreaction.

Wrapped around this core is the TX-16 Pearl Reactive coverstock—Storm’s pearlized evolution of the famed TX-16 formula. Finished with Storm’s Power Edge Polish, this cover glides through the front part of the lane and responds crisply to friction on the backend, making it a reliable weapon for medium to heavy oil conditions.

A bold mix of black, grey, and white, plus a Cherry Vanilla Cupcake scent, makes the Phaze A.I. not only a technical powerhouse but also one of the best-looking and best-smelling balls on the rack.
