- BOWLING BALL CORE NAME: Roto Grip RST Core
- BOWLING BALL CORE SHAPE: Asymmetrical Core
- BALL LANE CONDITIONS: Medium – Heavy Oil
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.
