So how exactly does Roto Grip improve and expand upon already proven performance like that of the Infinite Theory?

Remember that ball motion is a culmination of the numerous factors like coverstock material, surface texture, porosity, weight block dynamics, layout, etc. When considering all of these variables, it is truly a technical feat to be able to balance all of these items and produce a bowling ball that meets the high standards you've come to associate with Roto Grip.

With the new Critical Theory, Roto Grip is expanding the Theory series with its first pearl Insight™ coverstock. Designed to maximize dry lane traction, this shell will help increase your entry angle and sharpen your break point (CATS testing proved that the Critical Theory created the most entry angle in the entire product line), all in an effort to help you strike more! Its textured 4000-grit surface increases the Ra value, minimizes oil sensitivity, especially at the end of the oil pattern, and maximizes your bowling enjoyment.

Wrap the new textured pearl Insight cover around the high-torque, asymmetrical Triliptic core and you have some horsepower. Drill your new Critical Theory with your favorite layout, throw it at the dry boards to the outside, and watch it charge back with authority.

ROTO GRIP – It's all about the ATTITUDE.
