The look and performance of this high-performance bowling ball make it nothing less than a Gem. The Roto Grip Gem introduces us to the Defiant LRG core which is the lowest RG asymmetrical core in the current Roto Grip line-up. This core enables the ball to rev up fast and continue strong! Not only is the core in this ball noteworthy but the coverstock is the extremely aggressive MicroTrax Solid Reactive. This powerful combination makes this bowling ball perfect for heavy oil conditions.
Aggressive coverstock, Sharp hook through pocket
More sensitive and prone to over reacting, Requires quick adjust to changing conditions.
Heavy Oil, Tournament Conditio
Yes, I would recommend this to a friend
- A Great asymetric core with awesome visuals for tracking rotation down the lane. The 2000Abralon finish does a great job plowing through heavy oil conditions, like a Sportshot league or tournament pattern. I have a 15lb and a 16lb that makes it easier for me than adjusting the release. Both ball weights have a sharp break that carries nicely through the pocket. Ball can get squirrely on dry lanes or when the lanes begin to break down. Requires a bit more attention to keep it clean and keeping the oil out of the coverstock.
Worked great on long patterns at 500 grit
No real issues with iy
Good ball from heavy to medium oil
Yes, I would recommend this to a friend
In am currently have a 203 average in tournaments. I am a stroker/fingertip style bowler. In Austin the lanes appeared to affected by humidity. But once I found my line, I was getting the high pin counts. During double/singles events, I bowled a high 233 during the morning and a 248 during the evening.
On Sunday, while at the Georgetown lanes, I bowled 60 pins over my total average. During the afternoon, I bowled eight pins over my total average, due to some missed lines and or spares. I could have gotten a higher total average with this bowling ball.
Overall, this ball consistently worked for me on the long patterns. I see a possibily of needing to bowl more to the inside with this ball on league/house shots. But, glad I got this ball just in time for my tournament.
This ball is awesome
Heavy oil

This is the best bowling ball that I ever thrown so far
Yes, I would recommend this to a friend
Wow. I picked my Gem up last night and Roto Grip nailed it. I am admittedly a Roto Grip fan but this ball does things that nothing else in my bag can do. Easily the strongest ball I have ever rolled. Looking forward to it's debut on league night.
Would this ball be good for high rev players? I like too buy weaker balls because of my high rev rate.
This ball would be good for someone with a high ball speed but if you have a high rev rate this ball is already designed to have a high hook potential so you may only be able to use this in the highest oil conditions.
I have the zenith. How would this compare. As well as being a low speed bowler?
This ball would be most similar to the Zenith Solid. I am not sure which Zenith you have but this has a duller finish and solid cover to help it react earlier on the lanes. If you have a slower ball speed you may prefer a ball that gives you more length.
What is the difference between the gem and the nova
How does this ball do in medium to light oil
Could you put a little polish on it to longer
Does the 13# ball has the same core as the 14-15# balls have?
The 13lb ball has a different weight block. Here is a link to view the differences on RotoGrips website: https://www.stormbowling.com/gem-bbmrgm12
What is difference between the gem and nova
The Gem is going to read earlier than the Nova to give it a smoother arcing hook. The solid coverstock on the Gem reads earlier than the hybrid cover on the Nova and also the duller finish on the Gem helps it to start hooking earlier.
I’m a lefty, i role a fast straight ball.Will this ball help me get to the pocket once I place on my mark
If you are speed dominant then this could be a good option for you as the ball is designed to start reading earlier on the lane for a smoother arcing hook. If you do not have a high rev rate then this ball could work for you on medium to heavy oil and being that you are left handed the left side of the lanes tends to hold oil longer because less bowlers are left handed and it will not dry out as quickly because there is less traffic on that side of the lane.
I am looking for a replacement ball is a slightly lighter weight for my original Hyper Cell. How does this ball compare to the Hyper Cell? Similar specs?
In the current Roto Grip line the Gem would be the most comparable to the Hyper Cell. Both have a solid reactive cover and 2000 grit finish to help them read earlier on the lanes for a smoother arcing hook and both work in heavier oil conditions. The other options to check would be a Storm Proton Physix and a 900Global Reality.
Hi have a lot of ball speed not a whole lot of revs woukd this ball be good for me
Yes, this would be good for someone who was speed dominant. The ball is designed to try and read the lanes earlier so if you have a high speed you want to make sure the ball reads earlier so it has enough time to react.
With ball is stronger motiv trident or roto grip gem
The Gem will read slightly earlier than the Trident would and this may give it a slight higher overall hook but it would be very very close. Both are high performance balls and both are designed to work in heavier oil conditions. They are very comparable in performance.
I just got this ball lass week,and i throuh a 719 for 3 game.how maney game should i bowl before taking it to the pro shop to get servis.and whot should thsy be useding .
We hope it brings you some more high scores. If you start to notice that the ball is not performing as well as you would like then you can take it to your proshop for service. It will help if you use a towel in between shots to keep the oil and dirt off the ball as much as possible and if you have a cleaner to use at the end of each night that can help the ball last longer.
How would this ball react for a two hander who throws 16lbs with high revs and high speed?
This ball is a high performance ball with a high hook potential in heavy oil and reads in the midlane. If your ball speed and rev rate are both high you will still get this reaction but you may get slightly more length and a slightly higher hook potential than an average bowler. So that would make this really only good in heavier oil for you.
How does this ball compare to the Motiv Iron Forge and the Storm Incite?
This ball will read much earlier than the Iron Forge and noticeably earlier than the Incite. The stronger midlane read will help it to have a smoother arcing hook and this also helps this ball handle heavier oil conditions better.
I throw my ball between 14 to 16 mph with med revs. My house avg is 180. My go to ball is a ghost jackal which is great for dryer lanes when I go to state competitions the lanes are very oily, would this ball help me on the back end to get higher scores? Thanks in advance!
The solid coverstock and duller finish can help the Gem work better in heavy oil conditions. The Ghost Jackal is also rated to be able to handle some heavier oil conditions but if you do not get the reaction you like with this then you may prefer something like the Gem which will have more grip in the midlane to be able to rev earlier in heavy oil.
If your trying to create a arsenal would you choose the gem or the dna?
Hi Star, these balls are very comparable. It is hard to pick one over the other unless you have a personal preference. Both have great reviews, so I don't think you could go wrong with either choice!
Which is the most versatile ball reality,gem, or dna

Hi do you have a 14 lb to 14.5 lb in stock
i have the rst x-3 and trend 2 would this be a good ball to add to my arsenal
Hi I throw the ball at 16.75 to 17.15 down the lane and a lot of rev will this work for me on heavy oil down the lane that a Brunswick lanes that has no back ends
Yes, this ball is designed to have a strong hook potential in heavier oil conditions. Other similar bowling balls would be the Storm DNA, Hammer Extreme Envy, and Motiv Jackal Ambush.
