Roto Grip Nuclear Cell Bowling Ball Features:

The Nuclear Cell is the latest ball to use the asymmetrical Nucleus weight block from Roto Grip. This core has come in many incarnations of the Cell line, each paired with new coverstocks. The Nuclear Cell is no different, as it pairs this proven weight block with the new eTrax-P20 cover. This formulation is a very aggressive pearl that comes out of the box at a 1500 grit polished finish. The new cover is stronger in both traction through the oil and reaction to the dry than the previous versions of the e-Trax Pearl cover, such as eTrax-P18 that was used on the Idol Pearl and Halo Pearl.


Inside you will find the forever famous Nucleus Core. By far the most versatile asymmetrical core design ever created. No matter how it is drilled, or how you toss it down the lane, this core always gets into motion and stays in motion.


The R&D Team has been at hard at work mixing and formulating coverstock materials. Our newest version of eTrax Pearl contains a new chemical additive as well as ratio changes in order to produce better traction in the midlane and create more responsiveness to friction down lane.


There is no doubt the Nuclear Cell will quickly become a fan favorite and claim its place in everyone’s arsenal. If you want long and strong, leave it out of box. If you want it a little sooner and smoother, scuff the cover a little. Hands down, this will be one of the most versatile balls in your arsenal.
