Roto Grip Rubicon UC3 Bowling Ball Features:
The Rubicon UC3 (Ultimate Concept 3) takes Tour Level performance to a whole new level. Roto Grip first focused on core specifics and decided that the mildly asymmetric Rondure™ Core was the ideal core shape in order to generate adequate flare. From there they engineered the Tour-ethane Pearl coverstock to maximize performance and control on those higher friction patterns and lane surfaces. This core and urethane cover combination changes the game!
