Description
Roto Grip RST X-4 Squad Pro CG Solid
The RST X-4 Squad Pro CG Solid was engineered with the needs of high-rev competitive players in mind. Professional bowlers demand a ball that maintains continuous motion downlane with minimal deflection as it drives through the pins—and this design delivers exactly that.
Roto Grip’s R&D team focused on creating a core that preserves its dynamic integrity after drilling, ensuring the ball maintains strong torque and consistent motion. By placing a larger mass at the base of the core, the design guarantees that when the thumbhole is drilled—naturally near the bottom of the void—it has minimal impact on the core’s most influential mass. The result is a true Tour-Level core built for stability, continuation, and powerful downlane motion.
Paired with a reliable solid coverstock, the RST X-4 Squad Pro CG Solid offers a strong midlane read with the heavy rolling continuation elite players rely on in challenging or higher-volume conditions.
