Track - Robo Rule
Description: Designed for heavy oil, its u-shaped flip block moves more mass away from the center of the core, creating more energy for the backend. And the light load GP2 coverstock allows it to do it all without sacrificing strong midlane reaction. So what exactly does all of this mean to you? Simply that you get the best qualities of a symmetric core in a powerful asymmetric design. Brought to you by the design team at Track. Because we believe bowling better isn't about being the loudest, it 's about bowling smarter.
