Roto Grip Nucleus Bowling Ball Core
The Nucleus Core is hands down the most versatile asymmetrical core design ever created in the history of forever. First seen in the original Cell back in the day, this part has withstood the test of time and still performs better than most. No matter how it is drilled, no matter the rev rate, no matter the ball speed, this core always gets into motion and stays in motion all the way through the pin deck.
