Roto Grip Gem

The look and performance of this high-performance bowling ball make it nothing less than a Gem. The Roto Grip Gem introduces us to the Defiant LRG core which is the lowest RG asymmetrical core in the current Roto Grip line-up. This core enables the ball to rev up fast and continue strong! Not only is the core in this ball noteworthy but the coverstock is the extremely aggressive MicroTrax Solid Reactive. This powerful combination makes this bowling ball perfect for heavy oil conditions.
