Roto Grip Announces New Sinister Bowling Ball

At this year’s 2014 Bowl Expo, Roto Grip announced 5 new bowling ball additions to their line, including the all new high performance Sinister bowling ball. Watch Stuart Williams test it out in the Sinister bowling ball video above.

Ball Description

[custom_frame_left shadow=”on”]roto-grip-sinister[/custom_frame_left]From out of the shadows, I emerge as the winner. The moment I hit the lane, I dominate my foes and leave them
agonizing over what’s coming next. My all-new Cage™ Core is the nucleus from which my rage builds, leaving my
competition contemplating their exit strategy. They can either bow out now, or leave with their heads in their hands.


What my competition can’t see is that I’ve taken every step to ensure their defeat before I even arrive. My newly designed Cage™ Core is a premeditated plot to produce superior midlane motion without sacrificing down lane continuation. Did they think they had a chance?


I lie in wait, ready to ambush my rivals with a wicked one-two blow. The pearl portion of my 76H™ Hybrid Reactive Coverstock eases through the front end while the solid part provides sure-fire continuation through the breakpoint — allowing me to push my opponents past their breaking points.


I was created to devour heavy oil, but with my 4000-grit Pad finish, my scheme is to adjust my rough exterior to also combat medium to lighter conditions.
