Track Kinetic Obsidian Bowling Ball

TRACK KINETIC OBSIDIAN We’ve improved our famous Kinetic series of bowling balls once again. The Kinetic Obsidian uses our Modified Kinetic core, combined with a solid version of our DR-7 coverstock. The combination of the two provides excellent traction in the midlane with an aggressive change of direction at the backend of the lane. This is perfect for medium to heavy oil patterns. DR-7 SOLID Our DR (Delayed Reaction) series of coverstocks are typically used in conjunction with a polished finish. The combination of the two produce great length with a strong reaction at the backend of the lane. For the first time, we are offering this cover in a solid version with a sanded finish. By doing so, we created the strong midlane reaction expected from the sanded finish, while enhancing the reaction at the breakpoint do the inherent chemistry of the DR series. MODIFIED KINETIC CORE The Modified Kinetic Core is one of several popular cores in the Track brand. This low RG, medium differential and low MB core stores energy longer and responds quicker to friction compared to Track’s other mid performance cores.
