From the very beginning, Roto Grip's aim was clear for the Tour Dynam-X: to design and produce a cutting-edge bowling ball that revolutionizes performance with a fresh and focused approach. Responding to the requests of top-level tour players and skilled bowlers worldwide, they set out to create a ball that offers exceptional control, unwavering continuation, and minimal deviation, enabling them to conquer even the most challenging and reactive lane conditions. Roto Grip heeded their feedback and embarked on an intensive journey to develop the ultimate "TOUR PLAYER" ball. After numerous trials and a learning process filled with valuable mistakes, they successfully engineered a bowling ball that delivers optimal control and seamless continuation for every bowler, regardless of their rev rate. Their approach began by lowering the RG (Radius of Gyration) to initiate early core motion. This crucial adjustment resulted in the ball staying on its intended path for an extended period, reducing the typical directional change associated with high-performance balls. As if that weren't impressive enough, they also incorporated a mild asymmetry aspect into the design. This addition further enhances the ball's ability to maintain its trajectory while generating enhanced power as it drives through the pin deck, all while minimizing overall deflection. In summary, Roto Grip's relentless pursuit of excellence led them to create a game-changing bowling ball that fulfills the demands of tour-level players and skilled bowlers around the world. Its unrivaled control, seamless continuation, and extended precision on the lane make it the ultimate choice for those seeking an unparalleled bowling experience.
