After countless months of research and development, and after multiple tests and discussions with players of all skill levels, the Roto Grip ROCKSTAR provides a new motion and reaction for both the competitive player ranks and the advanced player ranks to shred and rock on those Medium to Heavy Oil Conditions.<\/p>\n

Offering new state-of-the-art technology in both the coverstock material and weight block shape design, the ROCKSTAR was developed to provide greater versatility on more oil conditions and lane surfaces than previous HP3 level balls since there have been plenty of advancements in the world of lane maintenance and lane surfaces in recent years.<\/p>\n

The new NanoStar\u2122 coverstock material is Roto Grip\u2019s latest nanotechnology remix. This union of nano particles mixed with new chemistry provides similar traction in the midlane to that of our legendary MicroTrax\u2122 material. However, the difference you will easily see is that the NanoStar\u2122 material does not dig into the lane as early as MicroTrax\u2122, it generates more responsiveness to friction down lane in terms of nanotechnology materials. In other words, breaking it down a little more for you\u2026 NanoStar is not as early as MicroTrax, and it\u2019s not as clean and responsive as our eTrax\u2122, eTrax PLUS\u2122, or eTrax ULTRA\u2122 materials. Therefore, it fills the gap between MicroTrax\u2122 and eTrax\u2122.<\/p>\n

Showcased at the center of it all you will find our newly developed weight block shape that is destined for greatness, known as the ROCKER Core. Its authentic shape encapsulated in A.I. Core technology provides a more centralized rotation plane to better provide more continuation through the pin deck. As always, the Roto Grip team of R&D rockstars aim to develop weight block shapes that perform for bowlers of all skill levels not just the ones you see on TV. Meaning, the ROCKER Core is no different, it was designed for the masses. Let\u2019s just say, the combination of amplified power and amplified motion results in sheer amplified awesomeness.<\/p>\n

So, if you are indeed ready to rock, then look no further, ROCKSTAR is here and ready to make you famous!<\/p>\n
