Roto Grip Perfect Gem (Pre-Order)

Pre-Order Expected Oct 2, 2026

The legend has evolved. We took the undisputed heavy-hitter of the GEM™ series and pushed it through our advanced A.I. Core Technology lab to create a ball that doesn’t just hook—it strikes with surgical intent. By strategically refining the core density, we’ve unlocked a new motion profile that retains the raw strength of the original while offering a cleaner look through the front of the lane and a more aggressive finish at the pins.
