Often imitated but never duplicated, the Nucleus Core dates back to the original Cell and has been a fan favorite since. Even though it is asymmetrical, it has the continuous roll of a symmetrical ball no matter how it is drilled.


The all new Radioactive Solid Urethane cover will produce the truest read we have ever seen at Roto Grip. Because it is urethane, it will blend out those over reacting conditions like a boss!


This ball was created with one goal in mind, design a urethane ball that provides more punch than all the other urethane balls on the market today. Safe to say we exceeded even our own expectations. No matter how you throw it, this ball rolls true every time and is a must for every tournament arsenal.
