Roto Grip Transformer High Performance Bowling Ball The Roto Grip Transformer truly lives up to its name, offering one of the most versatile and tunable motions in modern bowling. At the center of its performance is the innovative Morph-Wing Core, a dynamic asymmetric design that transforms more than any other core on the market once it’s drilled. By removing mass from the core’s distinctive wing, the internal weight shifts dramatically, significantly changing the core numbers and creating a completely different flare pattern and ball motion. This level of transformation is unmatched by any other asymmetric shape available today. Surrounding that powerful core is the V-R1 Solid Reactive coverstock. This nano-free material delivers the most balanced and reliable traction-to-reaction ratio in Roto Grip’s lineup, providing a strong read through the midlane with a smooth, controllable response at the breakpoint. The result is a motion that blends the lane exceptionally well while remaining predictable and consistent. What truly separates the Transformer from the rest is its ability to unlock multiple performance shapes from a single ball. For traditional thumb players, the unique design of the Morph-Wing Core allows for two distinctly different reactions depending on the drilling layout, making it easier than ever to fine-tune hook potential and breakpoint shape. The Transformer makes adding a specific motion to any arsenal simple, giving bowlers a level of control and customization that has never been easier to achieve.
