This union of nano particles mixed with new chemistry provides similar traction in the midlane to that of our legendary MicroTrax™ material. However, the difference you will easily see is that the NanoStar™ material does not dig into the lane as early as MicroTrax™, it generates more responsiveness to friction down lane in terms of nanotechnology materials. In other words, breaking it down a little more for you... NanoStar is not as early as MicroTrax, and it’s not as clean and responsive as our eTrax™, eTrax PLUS™, or eTrax ULTRA™ materials. Therefore, it fills the gap between MicroTrax™ and eTrax™.\u003c\/p\u003e\n\u003cp\u003eShowcased 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, our team of R\u0026amp;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’s just say, the combination of amplified power and amplified motion results in sheer amplified awesomeness.\u003c\/p\u003e\n\u003cp\u003eSo, if you are indeed ready to rock, then look no further,

Grip RST Hyperdrive","description":"\u003cp\u003eA long time ago in a bowling center far, far away...the world of bowling entered a new level of ball reaction unrest. There were countless oil conditions which added to the complexity of the game. During this revolution very few centers of bowling chose to follow the path of slicker conditions, while the greatest number of centers chose the path of less volume and less length which created more overall friction.\u003cbr\u003e\u003cbr\u003eDuring that time frame, we elected to develop bowling orbs that cleared the front of the lane more easily to combat those higher friction conditions and higher friction lane surfaces to better serve the bowling republic.\u003cbr\u003e\u003cbr\u003eMore recently, however, the cries for help have echoed loudly from all around the bowling galaxy. Those cries for help all requesting greater traction with asymmetrical power to combat and fend off those heavier and longer oil conditions. So, we enlisted the help of our R\u0026amp;D Troops to lead this mission to restore the peace against the oil rebellion.\u003cbr\u003e\u003cbr\u003eThey wasted little time in tossing their research efforts into HYPERDRIVE to create what was needed for the masses in both the competitive and advanced levels of bowling games. In reviewing our current roster of asymmetric bowling orbs, our team of R\u0026amp;D troopers found that we were in fact in dire need of a more advanced propulsion block encapsulated in our MicroTrax coverstock traction system.\u003cbr\u003e\u003cbr\u003eIt was determined during this intergalactic review process that the best block to insert into our A.I. Core technology was in fact the RST (Roto Star Tour) block design. The combination of this singular density asymmetric shape encapsulated inside of an A.I. Core created an ideal amount of accelerated spin and torque thus leading to greater propulsion, thus resulting in the name HYPERDRIVE being given to this beautiful galactic bowling orb.\u003cbr\u003e\u003cbr\u003eSo, as you find yourself battling the sinister lane man at your local bowling establishment, may you find yourself at peace with the assistance of the HYPERDRIVE to combat and destroy those heavier and longer oil conditions.\u003c\/p\u003e","brand":"Inside Bowling","offers":[{"title":"16 lb","offer_id":44950214377706,"sku":"RGBBMRYV16","price":199.99,"currency_code":"USD","in_stock":true},{"title":"15 lb","offer_id":44950214410474,"sku":"RGBBMRYV15","price":199.99,"currency_code":"USD","in_stock":true},{"title":"14 lb","offer_id":44950214443242,"sku":"RGBBMRYV14","price":199.99,"currency_code":"USD","in_stock":true},{"title":"13 lb","offer_id":44950214476010,"sku":"RGBBMRYV13","price":199.99,"currency_code":"USD","in_stock":true},{"title":"12 lb","offer_id":44950214508778,"sku":"RGBBMRYV12","price":199.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2327\/7029\/files\/Roto-Grip-RST-Hyperdrive-Bowling-Ball.webp?v=1740417749"},{"product_id":"roto-grip-ultimate-wrecker","title":"Roto Grip Ultimate Wrecker","description":"\u003cp\u003eThe HP2 Line is SOOOOO BACK BABY!\u003c\/p\u003e\n\u003cp\u003eThat’s right, after a brief hiatus, we felt there was no better time than now to resurrect and revitalize this gap in our product line.

Now some will say, “hey, I’ve seen that core shape before” and to those we say, “yes, yes you have.” BUT what we can also say is that you have never seen this MAXED-OUT version of this core shape before known as Rondure™ MaxD. That’s right, our team of mad scientists in the R\u0026amp;D Lab pushed this core shape to its limits by changing the densities of both the block and the slug on bottom to create the highest RG value and highest Differential value this part has ever seen. From its inception, this mild asymmetric shape was created to emulate the motion of a symmetric core shape with a balance hole in it. Fast forward to this newest version, and well, even though previous models were fantastic, this version is without a doubt the longest and most continuous down lane that we have ever seen.\u003cbr\u003e\u003cbr\u003eBut it doesn’t stop there, the mad scientists in the R\u0026amp;D Lab also managed to formulate a brand-new nano-free coverstock material during this development and testing process as well. That’s right, the versatile response (V-R1) cover formulation was created to handle a wide range of oil conditions and oil types. From the fresh, to the transition, to the burn, this cover provides easy push through the front of the lane while consistently responding to friction down lane without getting out of control.\u003cbr\u003e\u003cbr\u003eSo, if you are in the market for a pearlized ball that complements your big strong asymmetrical balls, or if you are needing a pearlized ball that allows you to move deeper on the lane and still comes around the corner, then you must add one of these to your bag.
