Additional product information:

CORE TECHNOLOGY: The Rondure™ TOUR-X Core is a precision-engineered modification of the proven Rondure shape. By manipulating the internal mass densities, we have successfully lowered both the Radius of Gyration and the Differential. This intentional shift provides a highly controllable, medium-flaring asymmetric dynamic, perfectly tuned to deliver the smooth, professional-grade motion demanded by elite players.

COVER TECHNOLOGY: The V-R1™ Hybrid Reactive is an advanced, nano-free formulation designed for a more aggressive footprint on the lane. By utilizing a precisely engineered 2:1 ratio—blending two parts solid & one part pearl—this coverstock achieves a potent balance of unadulterated havoc and refined predictability. The solid components ensure maximum mid-lane traction, while the pearl additive provides more response through the backend. The result is a tour-level coverstock that offers consistent & continuous motion.

PERFORMANCE SYNOPSIS: Engineered specifically for bowlers seeking more overall control and a predictable, continuous motion throughout the entire lane. The combination of the Rondure™ TOUR-X Core and the balanced V-R1™ Hybrid Coverstock creates a highly versatile and tunable ball that excels on a wide variety of oil patterns, making it a staple for any competitive arsenal.

    Gremlin Tour-X

    Posted by Chase Valenzuela on Apr 1st 2026

    Gremlin Tour-X is Roto Grip's newest lower-diff asym. This type of ball is becoming more and more vital in a post-weight-hole world, and Gremlin Tour-X provides a unique and complimentary shape to the like of Ion Pro and Ion Pro Solid. The Ion Pro core lacks a flip block, and this makes the motion really smooth and predictable. The mild asymmetry helps the Ion Pro make the corner. Gremlin Tour-X is familiar to its predecessor, the Gremlin. Although the differential has been lowered, Gremlin Tour-X corners much harder than either Ion Pro. The cover formula on the Ion Pro is also stronger and can get a little early/flat as the lanes transition. Gremlin Tour-X stores more energy and is more angular off the spot but still maintains a relatively even "Tour" motion that is more usable as the lanes begin to hook. If you like the Ion Pro Solid but have trouble getting it to clear the front/corner, Gremlin Tour-X is a perfect fit! -Chase Valenzuela

    Gremlin Tour X Review by Kyle, Joel, & Dean Johnson

    Posted by Kyle, Joel, & Dean Johnson on Mar 31st 2026

    Roto Grip Gremlin Tour X Coverstock: V-R1™ Hybrid Reactive 4000 grit Core: Rondure™ Tour-X (Asymmetrical) Color: Smoke/Velvet/Ink Review: Don’t let the craze and hype of the bionic turn you away from the Gremlin line. Despite not seeing a lot of use early in the PBA season, The original Gremlin and now this Gremlin Tour X are very complimnetary pieces. The Gremlin Tour X we feel like is more versatile for its predictability, control of the pocket, and smooth shape. If you were a fan of the Ion Pro, this ball is basically a direct replacement. One notiveable difference from the Ion Pro is this Gremlin Tour X seems to respond and take surfaces changes better. It looks great with many different grits and even with some polish. Overall this ball is one that can look good on the fresh for medium patterns, great for that 2nd ball out of bag on heavier conditions when you start to lose control of the pocket, and even better if you are looking for a “ball down” from a bigger ball like a hyperdrive solid, ion max solid, or equinox solid.

    Roto Grip Gremlin Tour X

    Posted by Dannial Cohen on Mar 31st 2026

    Roto Grip Gremlin Tour X Ball Review The Gremlin Tour X features the Rondure Tour X core. Roto Grip adusted the densities from the Rondure Max D Core found in the original Gremlin which lowered the rg and diff. RG-2.48 Diff-.034 PSA-.011 Surface-4000 Grit Abralon Coverstock-VR1 Hybrid Coverstock Layout-VLS 4.5x4.5x4.5 The Gremlin Tour X will be a smooth and very controllable option in the Roto Grip lineup. I compared the Gremlin Tour X to the Tour Dynam-X,Gremlin and Concept. Compared to the Tour Dynam-X i found the Gremlin Tour X to be cleaner with a little more pop on the backend. Compared to the orginal Gremlin i found the Gremlin to be cleaner with a sharper backend. Compared to the Storm Concept the Gremlin Tour X was cleaner with a little more response on the backend. I feel when your urethane or urethane type balls are getting lazy you can go right to the Gremlin Tour X and still have great control on the backend on medium lane conditions

    Gremlin Tour-X

    Posted by Rich Kollmeyer on Mar 31st 2026

    The Roto Grip Gremlin Tour-X is a controlled asymmetric hybrid that fits right into that benchmark/transition slot, but with a much smoother and more predictable shape than most asyms. It features the Rondure Tour-X core with a lower diff, wrapped in the V-R1 Hybrid cover at 4000 grit, giving it a very balanced, controllable motion. I drilled mine 4 1/2 x 4 x 2, similar to how I drill up most of the tour line balls. The Tour-X feels like a cleaner, more continuous version of the Ion Pro — still very controlled, but just a little more refined. It’s not a ball you’re using to open the lane up — it’s more of a “stay out of trouble” piece that you can trust when things get tricky. Out of the box, it hooked substantially more than I expected - I’m really hoping that tames down a bit over the next several games. Layout: 4 1/2 x 4 x 2 My Specs - Speed - 16 mph, Rev Rate - 280.

    Gremlin Tour X

    Posted by Gremlin Tour X on Mar 30th 2026

    Gremlin Tour X - Ball Specs Cover Stock: V-R1 Hybrid Coverstock Finish: 4000 Abralon Core: Rondure Tour X RG: 2.48 Differential: 0.034 Intermediate Diff: .011 Review The Gremlin Tour X is the newest addition to the Gremlin line series. The Gremlin Tour X reminds me of the Ion Pro Hybrid. The V-R1 Hybrid Coverstock paired with the Rondure Tour X core will allow me to play straighter on the fresh and move deep inside on the burn. As mid to low rev player l can to stand right of center on the fresh and as far left as 28 board on the burn without losing any carrying power. This ball will be in my bag for league and tournaments.

    Gremlin Tour-X

    Posted by Thomas Coco on Mar 29th 2026

    The Gremlin Tour-X is the newest addition to the Roto Grip line. This new ball is featured with the all-new Rondure Tour-X core, along with the VR-1 Hybrid Reactive Cover Stock. It is padded at 4000 grit out of the box and has a medium flare potential. The previous “tour” ball Roto Grip featured was the Tour Dynamix, which was very popular on the PBA Tour, as well as most tournaments I competed in. The Gremlin Tour-X provides more control, a blended hook and backend motion balanced by the solid and pearl cover stocks. As a big fan of “tour” balls, especially throwing the IQ Tour and Dynamix, I was very looking forward to throwing the Gremlin Tour-X. Ball layout: 75 x 4 ¾ x 40. I have tested it a few times on a 42ft league pattern, as well as on 42ft PBA Scorpion recently. The Tour-X works so well at the start on the fresh. It blends out both patterns easily, as I could play a little straighter before opening my angles. With its weak core, the mid lane traction doesn’t tend to jump very quickly as it has a smooth blended shape in the backend. Once the friction started to show, I could move right a couple boards with my feet, and the ball still responds smoothly into the pocket. Surface adjustments can be used, depending on what patterns you are bowling on. The Gremlin Tour-X tends to be a little stronger than the Dynamix. I find the Gremlin Tour-X to fit all varieties of bowling styles, and it is a great addition to have in your bag. Head on out to your local Storm Vip Pro Shop and drill up a Gremlin Tour-X today, you won’t be disappointed!!

    Gremlin Tour-X

    Posted by Darren Wong on Mar 29th 2026

    The Gremlin Tour-X is part of the Storm Tournament Collection and fits right square in the middle of the arsenal. As the name indicates, it’s part of the Gremlin series, but is a “tour” version so it emphasizes control instead of crazy ball motion. It essentially is intended to provide “professional-grade motion.” The original Gremlin is a great ball that has been a little overlooked by me and many pros I think because it was released at the end of the year when most of the PBA season was over. In the current environment when many bowlers are infatuated with big back end motion or dramatic ball motion, I was really excited for the Gremlin Tour-X because I was hoping it could be a controllable ball that can be used on a variety of patterns. The coverstock is the versatile reactive V-R1 featured on the Gremlin, but on the Tour-X, it’s hybrid rather than pearl and comes factory sanded at 4000 grit. This makes it smooth rather than skiddy and quick response. The core is the Rondure Tour-X which takes the Gremlin Rondure Maxd and tweaks the densities to lower the RG to 2.48 (in the 15#, compared to 2.50 in the original Gremlin). That lower RG combined with the hybrid ensures it won’t skid too far. The differential and the intermediate dif are both low at 0.034 and 0.011, respectively, which is what you would expect for a tour, control piece. That means it’s more about the operator than the equipment making the ball motion. Still, the little bit of asymmetry does help it read the mid lane. I heard many compare it to the Ion Pro Tour (it even looks like it). But to me, the Ion Pro Tour was a little quick and got forward on me while Gremlin Tour-X has a more rounded and continuous shape. I drilled the Gremlin Tour-X 4.5” pin to PAP x 4” pin to PSA x 2” pin to VAL. I took the Gremlin Tour-X to USBC Open Championships and it was exactly what it was supposed to be. In Team event, we broke them down in the track so by the middle of game 2, I put the Gremlin Tour-X in my hand and hit 18 at the arrows and wanted the ball to get just right of the range finder down lane (essentially 9). I proceeded to hit the pocket 19 out of the last 20 shots, threw the back 7 for 240 game 2 and 236 game 3. Everyone should have a Gremlin Tour-X in their bag as the perfect control, versatile middle of the bag ball.

    Gremlin Tour X – Smooth Control When You Need It Most

    Posted by Jerry Calabrese on Mar 28th 2026

    The Roto Grip Gremlin Tour X Bowling Ball is exactly what you want when you need control on tougher patterns. This ball is designed to be smooth and predictable, and that’s exactly what I’ve seen from it on the lanes. I drilled mine 4 ¾ × 4 × 4, and the reaction is exactly what I was hoping for. The ball gets into a nice roll, reads the midlane well, and most importantly doesn’t jump off the spot. Instead of that sharp “hockey stick” move downlane, it makes a smooth, controlled move and keeps going through the pins. The motion is very continuous and easy to trust. I actually drilled this ball specifically with Nationals in mind, because I sometimes struggle when balls get too quick off the end of the pattern on sport conditions. The Gremlin Tour X does the opposite—it blends the lane and keeps the reaction predictable, which makes it much easier to stay lined up as conditions change. If you’re looking for a ball that takes the over/under out of play and gives you a smooth, reliable motion, the Gremlin Tour X definitely does what it was designed to do. It’s the kind of piece that really shines when the patterns get tougher and you need control more than anything else.

    Gremlin Tour-X

    Posted by Todd Benner on Mar 27th 2026

    The new Roto Grip Gremlin Tour-X features the V-R1 hybrid coverstock finished at 4000 grit abralon, and the Rondure Tour-X core. At 15 pounds, this ball has a low RG of 2.48 with a differential of .034 and an intermediate differential of .011. I drilled this ball at 5x5x2 putting the pin above my bridge. This ball is very different than the original Gremlin, so don’t let the nameplate fool you. Many people compare this ball to the original Stom Ion Pro, but for me the Gremlin Tour-X is a stronger overall ball and has a more angular backend motion. The new Gremlin Tour-X will provide the bowler with high usability on many lane conditions, making this a must purchase for any league bowler who bowls in a high friction center, as well as any tournament bowlers who need a ball they can rely on to provide a consistent reaction when the scoring pace is on the lower side.

    Roto Grip Gremlin Tour-X – Ball Review (Tweener Perspective)

    Posted by Scott K. on Mar 26th 2026

    As a right-handed tweener with a PAP of 1" up and 3.5" over, about 14 mph ball speed, and roughly 330 RPM, the Roto Grip Gremlin Tour-X has become a very reliable option in my league bag. I primarily bowl on a 40' house shot on synthetic lanes with built-in friction, and this ball matches up extremely well with that environment. The first thing I noticed with the Gremlin Tour-X is how smooth and predictable the motion is. It gets through the front of the lane clean without burning up early, but it still reads the midlane strong enough to avoid skidding too far. For my speed and rev rate, the reaction shape is a controlled arc rather than a sharp flip, which helps keep the ball in play even when I miss slightly right or left. On a typical house shot, I can start around the second arrow and let the ball make a smooth move toward the pocket. As the lanes transition, the Gremlin Tour-X still retains plenty of energy, allowing me to move a little deeper without losing continuation through the pins. What really stands out is how well this ball blends the wet/dry conditions that house shots tend to create. It doesn’t overreact when it touches friction, and it doesn’t quit when it sees a little extra oil. The result is a very confidence-inspiring ball motion that makes it easier to repeat shots.
