After countless months of development and testing, it was determined that creating a core with a small asymmetrical split is what was needed to fill the newly created gap in the Roto Grip product line. The reason it is a newly created gap is due to the new USBC Rule that went into effect on August 1st, 2020. That rule eliminated the use of balance holes, thus creating a need for a different type of ball motion and reaction, that is where the NEW Roto Grip Rubicon™ comes in.

Once the R&D Team created the Rondure™ Core shape, they then went to work dialing the core numbers to get them where they needed to be. The concept was to create a core that would compare/replicate the motion of a symmetrical ball with a balance hole. Thus, making a ball stronger than a traditional symmetrical core ball, but not as strong as the typical asymmetrical core ball. The happy medium or gap filler if you will.

After the core development process was complete, the next step was to determine the ideal coverstock to wrap around the newly created Rondure Core. Countless tests by countless styles of players brought us to the eTrax-S20™ Solid Reactive formulation. This is our purest form of reactive material which also happens to be one of our most responsive covers to friction as well. Translation, the cover is super versatile and pliable, making it user friendly on a vast array of conditions.

All in all, it is safe to say the Rubicon is sure to secure the place of the “Benchmark Ball” in everyone’s bag for many years to come.


Roto Grip’s mission is to give the daredevil and adrenaline junkies a bowling ball brand that they relate to and that allows them to express their individualism and style.
