The Rocket A.I. builds on a name bowlers have trusted since 2015, when the original Rocket became a go-to in the Thunder line for its easy length and strong downlane motion. This version is dialed in for today’s medium to dry lane conditions, offering stability through the front of the lane and a defined, responsive backend motion. The proven Booster Core returns, now enhanced with A.I. Technology, and pairs with the advanced A1S Pearl Reactive coverstock to boost forgiveness and improve carry. As Jason Belmonte puts it, “When the lanes get a little toasty we need bowling balls that are designed to create more length and later ball motion… It will send your scores to the moon.”
The Typhoon marked a successful revival of the iconic Storm Hot line. While it excelled on drier conditions, it quickly became clear it needed a stronger partner to tackle heavier oil. Enter the Monsoon — built to handle more volume with confidence. Featuring a Reactor Solid coverstock finished at 2000-grit Abralon, the Monsoon creates a wider footprint on the lane, delivering more traction on medium oil conditions. Inside, the Atmos A.I. Core strikes the ideal balance of length and torque at the breakpoint, while our A.I. outer core technology unlocks a unique RG/Diff combination rarely seen in a core of this shape. Add in up to a 5% higher strike percentage on off-pocket hits, and you’ve got the perfect companion piece for conquering a wide range of medium oil patterns.
For those who loved the original Alpha Crux, or never got the chance to throw it, now is your opportunity to see what you were missing. The Alpha Crux returns, upgraded for today’s conditions and ready to dominate heavier volumes of oil. Bowlers can expect that dependable Alpha Crux ball motion: strong and predictable through the midlane, a decisive move at the breakpoint, and exceptional control and power through the pins. The upgraded GI-26 (Game Improvement 2026) coverstock builds on the performance principles of the original, handling modern oil patterns while preserving the shot-to-shot consistency that made the first Alpha Crux a favorite. At the heart of the design, the Catalyst Weight Block returns, preserving the dynamic characteristics that defined the Crux Series. Paired with cutting-edge A.I. Core Technology, this system amplifies energy transfer and hitting power while enhancing overall motion, delivering a stronger, more effective continuation through the pins.
