 
  Roto Grip® strives to give you the Ultimate in High Performance bowling balls the Pure Fuel™ delivers a high octgane boost to your game.
We took the Cyclotron™ core from the original Fuel and Top Fuel and modified it to deliver more power and energy at the breakpoint. This translates into superior mid-lane reaction combined with intense backend force.
The Ultimate Grip™ Pearl Particle coverstock gives you smooth acceleration through the heads with strong mid-lane and explosive backend reaction. The coverstock is easily adjusted with the use of scotch-brite pads and polishes.
Ultimate Grip Pearl Particle Coverstock
Cyclotron II Core
The Cycloton II core is described as having a strong mass bias differential, but I was unable to find any specs. If you come across them, feel free to pass them along. Thanks! - Aaron
