Behind the Design:

There's no better time than right now to reignite those beloved memories of the late 2000's legend the CELL that put Roto Grip back on the proverbial map. X-CELL is our way of paying homage by blending the original look with our modern day core and cover technology to give players even more forgiveness and versatility than the original everyone loved. On the inside you will find the original Nucleus block wrapped in one of the greatest inventions since sliced bread, A.I. Core Technology. This core allows for greater energy dispersement from the center to the cover to increase overall pin carry. While on the outside you will find our brand new ULTRA versatile, ULTRA responsive - eTrax ULTRA Solid Reactive coverstock that features chemical enhancements mixed into the material to provide an ULTRA consistent reaction shot after shot.

    Dual Angle Layout: 40 x 4 ¼ x 75 Storm Vector Layout: 4 ¼ x 3 ¾ x 4 The new Roto Grip X-Cell reminds me a lot of the Storm Absolute Power. It is cleaner through the front of the lanes than most Assym Solids, and still picks up nicely in the mid lane, but due to the fact it’s cleaner it still has plenty of energy through the pins. This ball will be really good for anyone who has lower rev rate or higher ball speed on your typical house shots. For anyone who loved the original Cell this ball will provide that nostalgia you’re looking for. Comparison video with the Harsh Reality:

    Roto Grip X Cell

    Posted by Matt Fazzone on Jun 19th 2024

    The X Cell is the latest HP4 line ball from Roto Grip and brings back the famous Cell name. The Nucleus Core now features AI Tech and is wrapped around the eTrax Ultra Solid cover stock. Now I drilled my X Cell with a little different layout than I normally do because I was looking for it to do a specific thing, 4 x 4.5 x 2.5. I brought my Harsh Reality to test against it and I was quite shocked on the motion it made. Even with the stronger drilling in it, it was able to get down the lane with ease and the continuation it gives is incredible. It seems like the ball just struck from anywhere. I believe this ball is going to bridge the gap when the bigger asymmetric solids are just a little too much and the stronger symmetrical solids aren’t quite enough. Lower rev rate players will also love the strength this ball gives them without worrying about how it goes through the pins.

    Roto Grip X-Cell Review

    Posted by Tobias Myers on Jun 18th 2024

    The Roto Grip X-Cell features the eTrax ULTRA Solid Reactive cover, Nucleus + A.I. Core, and comes at 2000-grit. This is the newest release in the cell line and has been awhile since we have seen a cell ball. This ball is going to be a ball down from the Gem and just below the Pi and Reality. The X-Cell is cleaner and gets down the lane a bit further than those balls for me. This ball is in the Eternity Pi range for strength but a bit longer and more down lane shape. The Pi is my go to ball right now for heavy oil and when it starts to read the lane too soon then the X-Cell is a great ball to switch too. This would be the same for the situation for the Reality for those who love that ball. This ball does not disappoint and it is a home run for Roto Grip!! Tobias Myers #RotoGrip #SquadRG

    X-Cell Review

    Posted by Adam Chase on Jun 18th 2024

    Layout: 4 1/2 x 4 1/2 x 2 1/2 Surface: 2000 Abralon Rev Rate: 470 RPM The New X-Cell brings back the iconic Nucleus Core from the original Cell series while adding in the AI Core technology. The coverstock is the brand new E-Trax Ultra Solid which is a steppingstone between E-Trax and E-Trax + coverstocks. I got the chance to try this out on a 47ft, medium oil volume sport pattern. What I saw was what you would typically expect in a higher end solid bowling ball, strong midlane and backend motion. Comparing this to the Gem, I saw cleaner overall motion where the X-Cell got to the midlane pretty easily and it had a more angular backend. The Gem was still overall stronger, earlier rolling and smoother overall which allows both balls potentially in an arsenal. Compared to an Optimum Idol, I saw more overall strength as expected while it still wasn't as smooth. I got a little more angular ball motion then the complete controllability of the Optimum Idol. I was able to move about 8-10 boards left of my starting spot before the Cell became too early and slow responsive. I was able to ball down to an Attention Star and continue to strike from the same zone on the lanes. I recommend this ball to someone looking for a heavier oil/fresh ball on higher friction or older lane surfaces as it is cleaner than the Gem. The asymmetry of the core gives this ball a lot of flair potential which will be able to handle most fresh conditions. Adam Chase Storm Staff

    Roto Grip X-Cell Review by Lonnie Pembertron

    Posted by Lonnie Pemberton on Jun 8th 2024

    TESTING ENVIRONMENT Length:43 Volume:Med-High Type (THS, Sport Pattern etc):THS 12:1 Ratio BALL: Coverstock: : eTrax™ ULTRA Solid Core: : NUCLEUS™ + A.I. CORE Finish: 2000 Abralon RG: 2.50 (15lb) Differential: .056 (15 lb) ME: Right-Handed Tweener Speed: 12-13 mph Rev Rate: 315 Axis Tilt: 14° Axis Rotation: 74° PAP: 5 1/8 R 7/8 Up Ball Layout: Pin Up 5 1/2 X 4 1/2 X 2 1/2 VLS The ball that put Roto Grip on the fore-front of high performance bowling balls is back. The legendary cell line with the powerful Assymetric Nucleus block was for many the best HP ball every released by Roto Grip. The GOAT is back with AI technology in the form of the new X-Cell. To compliment the legendary core it has been wrapped in a powerful and responsive eTrax Ultra cover. This cover gives you more length than Micro-Trax but a bit more mid-lane dig than ETrax Plus. The result is a consistant, versatile and trustworthy ball-motion to overpower the lanes. I tested the X-Cell in my home center on a fresh lane that had sat for a bit before I got to it. I lined up around 20 with my feet Looking to push the ball from around 15 to 7 and watched the ball see the spot and go and go and go. I immediately made about a 7 board move left with my feet and opened the angle. I still needed to keep the speed up but my next shot easily covered the increased distance and pushed the rack back into the pit. My biggest astonishment was how easily I managed to get the ball past the front panel (lots of built in friction here) without it wanting to bleed all it's energy off right away. For a ball that gives such a great mid-lane read this ball really retains energy well, making it strong it pretty much every phase. I tested it again in league a few days later, expecting to see a reduction in initial hook as I wasn't sure how much the oil had changed from sitting so long before I had gotten to it on the previous occasion. Surprisingly there was only a couple board difference and by the end of practice I was right back where I had been the last time. The lanes have been tight as of late particularly down-lane but my X-Cell never had the chance to bog down in the Out of Bounds outside down-lane because it had no problems reading the right part of the lane to already be hooking by it. I would recommend this ball to literally anyone. It's more than powerful enough for rev-challenged bowlers and if I can get it down-lane it shouldn't be too much for anyone who is speed-challenged or rev dominant. This is a top of the bag option that everyone will be happy with.
