Roto Grip Gremlin Bowling Ball

(3 reviews) Write a Review

Your new favorite pearlized ball has been hatched to help advance your game in ways you didn’t know you needed. 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&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.

But it doesn’t stop there, the mad scientists in the R&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.

So, 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. But you don’t have to take our word for it. Try it for yourself, we know you will like it. Oh, and don’t worry, it won’t multiply after midnight if there is oil residue left on the coverstock… Or will it?

  • Staff Review - Roto Grip Gremlin

    ? Staff Review – Roto Grip Gremlin ? Layout: 5 x 4 x 2 | ReactaGloss™ Finish Bowler Specs: 475 revs | 12° tilt | 45° rotation | PAP: 4¾" x 1" up ? The Rundown: The Gremlin might look fun-sized, but don’t be fooled—it’s a serious piece. Built with the new V-R1 Pearl cover and a maxed-out Rondure core, this thing glides through the fronts and hits the corner like a possessed pearl. ⚖️ Ball Comparison (Real Talk): Ball up from a Hyped Pearl Earlier and smoother than TNT Infused Cleaner and flippier than Exotic Gem ? Best Use: When the lanes are transitioning but you still want angle League nights when the fronts go but the backends stay strong Tournament days when symmetric motion isn’t quite enough ? My Take: Super versatile—reads early enough to control the midlane but doesn’t quit downlane. You can move in and trust it to come around without jumping or stalling. Great addition if you need something between your benchmark and your big asym.

    Ball Specs: Roto Grip Gremlin Cover stock VR-1 Pearl Reactive Rondure™ Maxd Core (Asymmetric) Power Edge Finish Layout 4 x 4 x 1.5” Pin Buffer Bowler Specs: Right Hand. PAP 5” Over 1/2 up Rev Rate 300. Tilt 20. Rotation 50. Speed at release 17 Review: I have been waiting to roll the Gremlin ever since I saw the specs on it. This ball is a beautiful mix of purple colors, and the green logos look great in contrast. The Gremlin was much more predictable at the breakpoint than I expected considering the high RG value. I think this is due to the asymmetric core and the new cover stock. The Gremlin covered more boards than I expected but remained controllable. This ball has a very good price point and has already created a buzz at the shop. I would put this ball above my Hustle M&M, but below my Harsh Reality pearl in total hook. I have used this ball at a couple of bowling centers now and what I’m seeing is, as the shot gets worse the ball gets better. The Gremlin is a ball I think I can keep in my hand for a long period before going to something else. The lighter hits seem to move pins around a bit, which is also fun to watch. I have very good expectations about this ball. Summary: The Gremlin is a very attractive benchmark ball. This ball is forgiving versatile. The Gremlin is a performance ball at a very good price point. Glenn Wendel Sidewinders Pro Shop Storm Pro Shop Staff gwendel@comcast.net www.stormbowling.com

    The Gremlin’s modified core simply is amazing. I was able to try this ball on the fresh and the burn and it gave me a great look. The ball on the fresh, I was able to play a little further right around 7-8 board at the arrows. The ball definitely started picking up a touch sooner than I expected but the lanes this summer have been playing with a bit more friction than last summer. Now I was able to jump back on the same lanes at the end of the night after the league and I was blown away with the versatility of this ball. My first handful of shots I was rolling the ball around 15 at the arrows out to about 5 and the ball just ripped off the spot and continued through the pins. Moving a little more left I tried to throw around 20 at the arrows to keep it a little tighter and a handful of shots I missed in gave me some good mix strikes. But the ones that seemed to get to the 12-14 board area on the lane came back high flush.
