Roto Grip Theory Bowling Balls
Put this THEORY to the test. The evolution of the bowling ball never has reached a level this advanced!
The Theory we are bringing to you is based on an exciting new interior shape called the Triliptic Core.
It's a triple elliptical shape that has a myriad of benefits from consistent axis migration to the ease of drilling and predictability of ball motion...it's all there! It takes lots of engineering to come up with a design this intense, and you can literally FEEL the blood, sweat and tears that have gone into the creation of this Theory.
Roto Grip - It's all about the ATTITUDE!
