Additional product information:
Dating back to the mid-1950’s, there is a reason Roto Grip is often referred to as the “Original High-Performance Bowling Ball Specialists.”
Our latest asymmetrical creation continues that tradition with the development of the RST Core which produces consistent core torque and energy transfer down lane where it is needed most.
From there we formulated the most versatile MicroTrax Hybrid Coverstock to date which produces optimum responsiveness to both oil and friction.
