Roto Grip Tour Dynam-X Bowling Ball

(49 reviews) Write a Review

From day one, the end goal was to develop and create a high-performance ball from a completely different dynamic performance-focused perspective. Tour level players and above average bowlers from around the globe have always asked for a ball that produces control and continuation with minimal direction change in order to battle those tougher and more demanding and over reacting conditions. They spoke, we listened! So, we went to work to formulate and create the ultimate “TOUR PLAYER” ball. And truth be told, after months and months of trials and errors, we were finally able to construct the optimum control and continuation for every style of bowler no matter their rev rate. Control, stability, and versatility unified into one dynamic ball that is a must for every single serious or semi-serious bowler.

When a symmetrical core shape just isn’t enough or quite right, and a big asymmetrical core shape is just flat out too much, the answer is simple – the Mild-Asymmetric Rondure Tour Core. Why is this version considered a “Tour” model you ask? We thought you would never ask. From the original version of this shape previously introduced and used in the Rubicon™ Series, we changed the core values significantly to create a faster revving version that stays on-line easier and longer with less change of direction due to the Differential value being cut in half. So, no matter how you throw this ball, whether you have a super high rev rate or a super low rev rate, or a rev rate somewhere in the middle, this Low RG, Low Differential, Mild Asymmetric Differential core produces a constant stable motion off your hand and all the way through the pin deck.

  • RotoGrip Tour Dynamix

    Posted by David Woods on Dec 16th 2023

    When RotoGrip discontinued the Rubicon it left a hole if you needed an asymetrical ball but you didn't need the really strong cover stock to blend out the lanes. I decided to go with a 5x4x1 in 14lbs so that I had a ball that would shape downlane instead of roll early like the Gem or RST X3. I was pleasantly surprised when I threw this ball. I could get it a little right and it would recover and carry. If I missed a little to the left it seemed to get down the lane far enough that it wouldn't just pile into the headpin. I bowl on a typical 44ft house shot where this ball is not quite enough coverstock when it is fresh but once the lanes start to open up the Tour Dynam-x is like an !Q Tour on steroids. I would not recommend this ball for really long oily conditions or very dry conditions but most players will be able to find a spot in the middle of their arsenal.

  • Tour Dynam-x

    Posted by Todd Benner on Dec 15th 2023

    The new Roto Grip Tour Dynam-x features the Rondure Tour Core wrapped in Tour Trax solid reactive coverstock. At 15 pounds the ball has an RG of 2.47 with a differential of .026 and an intermediate differential of .010. I drilled this with the pin above the bridge. The Tour Dynam-x low differential will allow bowlers to keep their angles closed longer and play closer to the friction than most reactive balls would. This ball is a must have for tournament players as well as league bowlers. The Tour Dynam-x is very controllable for the tougher patterns as well as blending out the wet/dry house patterns. This is a heavy rolling ball which not only excels at going up the boards, but it also performs well when you need to open your angles a little bit. This is one of those balls that won’t wow you with overall hook or backend motion. All it does is give the bowler a consistent reaction with excellent pin carry, keeping you out of trouble and in the pocket striking longer!!

  • Tour Dynam-x Review

    Posted by Sandra McIntire on Dec 15th 2023

    I am a higher speed, rev challenged 220-250ish, high tilt, high rotation, and super low track player. I drilled my Roto Grip Tour Dynam-x 5 5/16 x 3 x 2 and my axis point is 3 ¼ right and 7/8 up. The Roto Grip Tour Dynam-x is a small asymmetric solid reactive piece that I really like to use on short and medium volume patterns. The low Rg and small diff gives this ball medium- high flare potential when I need something to spin up fast, be clean, smooth, and controllable this is the ball to go to.

    About Me 900 Global Staff Left Handed: High Rev High Speed Player Pap: - 47/8 +1 Rev Rate: +-500 Speed 17-18mph Layout: 4 ¾ X 3 ½ X 1 Ball Video: N/A Sneaky good and very predictable. I haven’t had a chance to throw the Tour Dynam-X very much before I had surgery. The Dynam-X was definitely stronger than I expected. I had heard different reviews on what this ball was supposed to be. I heard it was supposed to be strong and I also heard that it was supposed to be weak and roll more like urethane. Both of those reviews are correct. What I mean by this is the Dynam-X is a strong ball but has a roll like urethane. The reason I say it rolls like urethane is because of how early it picks up on the front part of the lane and starts reading the pattern and then gets down lane and breaks and has the nice strong controllable finish through the pins like urethane. No, I am not saying that this is taking the place of your urethane equipment because it’s not. What I am saying is the roll reminds me of a very, never seen before strong urethane ball. The Dynam-X hooks like a solid and is very controllable and hits like a tank. I truly believe that the Tour Dynam-X is going to be useful on all different types of patterns, be very versatile and shoul make your line up, I know it’s making mine.

    Layout: 4 1/2 x 4 x 3 1/2 PAP: 5 1/8 x 7/8 Up Rev Rate: 315 Axis Tilt: 27 degrees Axis Rotation: 45 degrees I drilled my Tour Dynam-X 4.5 x 4 x 3.5 and I was really looking forward to throwing it. It has the Rondure Tour Core, which is a slightly modified version of the Rondure Core that was in all the Rubicon balls. The Rubicon Tour core has a slightly lower RG and intermediate differential, but a significantly reduced differential. I really wanted this to be a ball I could bail out to after the lanes get torn apart during league. My first reaction throwing the ball was “This ball HOOKS!” Needless to say, that’s not what I was expecting out of this ball. It took 7-10 games for it to really tame down and settle in, which has significantly reduced the amount of overall hook and has become much more of a control piece. I’m still not using it a lot on house shots, but it definitely makes the trip with me to any tournament I bowl in.

    Layout: 30 x 4 x 65 The Tour DynamX has a very unique ball reaction that, as intended, is best compared to the Storm IQ Tour. It is very smooth and predictable, though the added asymmetry gives it a touch more downlane kick. It does not pick up too early, and saves everything for the midlane. With surface, this ball is good on heavier or flatter fresh patterns. For me, the smooth arcing nature of this ball lends itself to being much better when straighter angles or a “down and in” line is needed. Once I have to move left, balls like a TNT Infused or Clone come around the corner better. I find that this ball is a great alternative to using urethane.

  • Strong climbing motion

    Posted by Jay Hendershot on Dec 7th 2023

    The Tour Dynam-x provides a look that all bowlers would welcome to their bag. I'm a right handed player whose style leans toward being rev dominate. Speed off my hand is in the mid 16 mph range. I drilled mine 45x4x35. This is my go-to layout and gives me lots of options. The Dynam-x is a low flare ball with a fairly strong cover and finish. On the lanes, house or tournament conditions, this ball provides a confidence inspiring mid lane off climbing shape. I like using it when I can stay on top of the shim with speed and chase it in. The dig in this cover alongside the slight asymmetry in the core makes this the play for me. It was a mere matter of moments after I got this one on the lanes that it was destined for my tournament bag. You can reach out to me on my Facebook page, "Throwing Bolts and Seeing Stars", if you have questions about this great piece.

  • Roto Grip Tour Dynam-X Ball Review

    Bowler Stats: Speed: 15.5 MPH Rev Rate: 275 RPM Tilt: 3-5 degrees Axis Rotation: 60 degrees PAP: 5 ⅜ over 1 ¼ up Layout: 41/4 X43/4 X 2 VLS With the release of the Tour Dyman-X during the PBA 50 Season I was not sure how I would match up with the design of the Rondure core. After seeing the core numbers and it being a weaker asymmetrical core I decided to put a stronger layout on it rather than my normal one. I thought it may give me a urethane type of motion off the end of shorter patterns since I didn't have urethane as an option in my arsenal. Unfortunately I think I missed on the layout because it’s very confused on the house and sport patterns. The 41/4 inch pin placement gives me the proper length with the weaker core but the 43/4 mass placement doesn’t allow the ball to flare enough when it begins to read the dry at the end of the pattern. I used a similar drilling I would use on an !Q Tour solid since this ball was to be slightly stronger with the same type of ball motion. I changed the cover to 1000 abralon by hand and that helped it read the house pattern for my ball review video but as it shined up it still was confused. I plan to drill another one and change the mass bias placement in the VLS layout to 4 inches and so it will flare more to match my lower rev rate. Pete Dohan Storm Bowling Amateur Staff #StormNation

    Newest addition to the Roto Grip HP3 line is the Tour Dynam-X. The Tour has a strong solid coverstock with a low rg (2.47)and low diff core (0.26). This is a unique combination. We really haven't had that combo in a ball from SPI. So hats off to the design team! I drilled mine with a pin up 4 inch pin. I have used the Tour on a bunch of patterns, very versatile. Its kind of cover strong like the IQ Tour solid. Ive been able to play inside 4th arrow and played up the lane around 1st arrow with the Tour. The cover responds with all kind of surface adjustments, whether it is with Abralon pads or step 2. The downlane reaction is probably a little on the slow response side, but the Tour for me carries real well. The Tour is kind of between an asymmetrical and a symmetrical ball. Even though the Tour is an asymmetrical ball, but with the lower diff it fits in between. Great ball to have in your bowling ball arsenal.

    Tour Dynam-x It says it all in the name... Tour. This ball exceeds on tougher conditions like the pros see on tour, but don't get me wrong this bad boy also works wonders on a house shot. With is smooth, predictable, and very controlled motion you get an asymmetric shape with the continuation through the pins like a symmetrical core would.

    Roto Grip Tour Dynam-X Layout: 4.5 x 5 x 2 Storm Pin Buffer Layout Rev Rate: 325 rpm, 7 degree of axis tilt, 40 degree of axis rotation Testing information: 41 foot THS (medium to light volume) Bowling Center: Fulton Bowling Center Kegel Machine – Brunswick Anvilane The Roto Grip Tour Dynam-X utilizes the Tour Trax solid coverstock and the Rondure weight block. My first thoughts are control and versatility. The Dynam-X is another option in that iQ Tour space. The Dynam-X can be thrown from straighter angles early and deeper angles later in the blocks. It will never be the ball to cover the most boards but can be thrown from left to right with modest board coverage. We had the Dynamix a touch stronger than the iQ Tour, which has to be the coverstock. The Tour Trax is a new generation solid coverstock that blends the trust-worthy Versatile Traction Control (VTC) coverstock from the Hustle line with some new additives to create a versatile bowling ball.

  • Tour Dynamx Control

    Posted by Sam Cooper on Nov 22nd 2023

    Sam C. Roto Grip Staff Layout:50x5x40 Name of the game with the Tour Dynamx is control. When this ball was announced I was very excited based off the numbers. Lower diff .026 with an intermediate diff of .10. The Dynamx feels like it is stronger than what the numbers say. Threw this ball on the challenge condition 42ft Kegal Chromium which is a shot we use for league I am in on Mondays. This ball let me play a tighter line to start with awesome continuation and power through the pins. You can tell with the way the labels rotate when the ball is reading the lanes and revving up and turning for home. With the little bit of asymmetry of the core it gets the ball moving on the back end more so than a IQ Tour or a Hyped Solid. The reaction is a strong arc. It gives you a very consistent read of what the lanes are doing as well. This will be a first ball out of the bag for a variety of conditions to get a read of what I need to do on the lanes. This ball will be great for people with higher rev rates like myself looking for control. Or even lower speed lower rev players that need to get a ball down lane with control!

  • Very Unique Shape

    Posted by Bradley Paynter on Nov 20th 2023

    The Tour Dynam-x is very unique, and for a good reason. It doesn’t over-flare, and allows you to keep your angles in front of you without sacrificing carry. As someone who too often moves left ahead of the curve, this ball allows me to stick to the right, play the proper part of the lane, and let the ball do the work for you. Amazing work by the SPI team on this ball.

  • Roto Grip Tour Dynam-X review by Ethan Fiore

    Posted by Ethan Fiore on Nov 15th 2023

    The Tour Dynam-X is our new solution for urethane! The Tour Dynam-X has our Rondure Core that was in the Rubicon Series, and the Tourtrax Cover. I see this ball being useful with a lot of friction. It has an early and controllable shape which you will see in a lot of urethane balls. But the low differential, this gets you as close as possible to that exact shape.

    My Specs: PAP: 4 7/8R 7/8up Revs: 350 MPH: 15 at pins Layout: VLS 3 3/4 x 4 x 3 5/8 Pin Down The Roto Grip Tour Dynam-X is a bowling ball that delivers control, stability, and versatility on tough and demanding lane conditions. It features the new Rondure Tour core, which has a very low total differential and a mild intermediate differential, creating a smooth and stable motion from start to finish. The coverstock is the new Tour Trax Solid Reactive, which has a rough 2000 Abralon finish that helps the ball pick up early and provide a controlled arc at the breakpoint. The Tour Dynam-X is ideal for bowlers who need a ball that can handle over-reacting or shorter patterns, as well as for those who prefer a rounder shape downlane. The ball can also be adjusted with different surface preparations or layouts to suit different styles and preferences. The Tour Dynam-X is a must-have for serious or semi-serious bowlers who want to compete at the highest levels of the sport. For my Tweener style I can describe the TD as an asymmetrical Hyped Solid. Not my first ball option in league, more of a third gamer on a THS due to my lower rev rate and speed. and not wanting to get steep with my angles. Great ball to keep in front of you when you need that control at the breakpoint or when you a readable shape. No lack in confidence when it comes to execution and continuation at the pin deck. Definitely a ball to have in your arsenal for the semi-serious and serious local THS tournaments and shorter sport patterns bowler. VISIT YOUR LOCAL VIP PROSHOP TODAY!

    Roto Grip Tour Dynam-X Coverstock: TourTrax Solid Reactive Core: Rondure Tour Factory Finish: 2000 Abralon Layout: 4 x 4 x 2 The Dynam-X quickly found a way into my league and tournament bag. It provides control and continuation while still having a nice strong reaction. I am not sure I have ever thrown a ball that does what the Dynam-X does on the lane. It pops off the dry but isn't anything resembling angular. The other control piece in the HP3 line is the TNT, which is a lot earlier than the Dynamic-X. The shiny options in the HP-3 line are the TNT Infused and the Duo. The Infused and Duo are clean and responsive to friction, much more so than the Dynam-X. The addition of the Tour Dynam-X allows Roto Grip’s HP3 line to cover a lot of bases of ball reaction. The Tour Dynam-X is a well rounded ball that covers a lot of bowlers and skill levels, especially in today's high friction lane environment where slow ball speed is a killer and controlling hook is king.

  • Ball of THE YEAR

    Posted by Johnny Quach on Nov 9th 2023

    One of the most versatile balls ive ever thrown, ive used it on short, medium, and long patterns, ive used it on house shots all across houston, its the first ball in the bag and first ball on the lanes. It takes everything i love of the iQ tour solid and makes it asymmetrical, which means i can get further left without worrying if its gonna miss the spot or be too clean. It hooks early without losing energy, it recovers when you miss out, ive never had a better stretch of weeks in league with any other ball, it still rolls great with surface or with lane shine, its just a great ball for any player. I am a two hander with about 450 revs but i feel like ive seen so many people match up with it, from up ten dumpers to regional tour guys, and especially some pros. Ive drilled two, with another one coming soon. Layout: 50x5x50, 40x5.5x35, next one will either be 50x2.5x60 or 40x4x40 to be even earlier and stronger

  • Roto Grip Tour Dynamx Ball Review by PJ Haggerty

    Posted by PJ Haggerty on Oct 31st 2023

    One of the newest additions to the HP3 line at Roto Grip is the Tour Dynamx. After drilling several balls a year from the Utah plant, I’d have to say this is one of the more unique ones I’ve drilled. Bowling as a game is evolving with the urethane rules frequently changing, and I believe the Tour Dynamix is a ball that can be used to try and replicate a urethane-type reaction while still throwing reactive. The numbers, characteristics, and shape of the Dynamx are unique and I think, impressive. The coverstock is extremely strong. It’s wrapped with the Tour Trax coverstock and inside is the Rodure core. With that combination, the numbers come out to 2.47 RG, .026 differential, and .010 PSA. With the differential being very low (IQ Tour levels), the Dynamx doesn’t flare a lot. When you drill it, I’d recommend drilling it closer to 4-4.5” from your PAP to make sure it flares enough. Don’t be shocked when you look at the oil lines and they are extremely tight together. It’s perfectly normal. However, when you throw it, this ball will read early, often and feel very strong. I think this could be a great ball to use to combat some of the urethane battles bowlers have. With a strong cover and low diff, I think this will eliminate a lot of that over/under bowlers notice when they are following urethane or having to complete against it. I’ve drilled one so far and really like it. It’s drilled with the pin below my ring finger with a good size shift of the CG and mass bias. The numbers come out to 4.5 x 3 x 30. I’m keeping this one relatively dull too. I’ve kept the surface at 2000 to make sure when it use it, it picks up and goes through the pins the right way. This ball is awesome! Just make sure you drill it stronger to assure it will flare enough!

  • Tour Dynam-X Review by Luke Rosdahl

    Posted by Luke Rosdahl on Oct 24th 2023

    User Specs: Left handed, 375 rev rate, 17mph speed, 45 degree angle of rotation, 7 degrees tilt Layout: 4 ¾ x 3 ½ x 2 ½ The Tour Dynam-X is a new mildly asymmetric ball in Roto Grip’s HP3 line. It features the new TourTrax cover which is medium to lower strength. The core is the new Rondure Tour core, which shares the shape of the original Rondure core from the Rubicon series, but the density has been adjusted to lower all 3 numbers down to 2.47 for the RG, .026 for the differential, and .010 for the intermediate differential in 15 pounds. On paper, this is a mildly asymmetric IQ Tour type of ball. The box surface is 2000, and it’s surprisingly strong at this surface. However, because it’s a medium to lower strength cover, it weakens significantly as it shines. However again, this makes it incredibly versatile. With surface it has the traction and stability to be in play on tougher sport patterns, and with shine it’s surprisingly usable and effective on league patterns. The super lower RG helps the ball control the midlane, while the low differential and mild asymmetry helps keep it very stable and controllable. The Tour Dynam-X feels like a smoother and weaker version of the Phaze 2. The shape is identical, the same slightly directional arc that’s very responsive to hand changes and physical adjustments. I think it’s an evolution of the IQ Tour Solid in that it does all the same things the IQ Tour does, but the versatility is increased substantially. Like I mentioned, the TDX is a step down from the Phaze 2 but a step up from the Hustle RIP.

    The all new Roto Grip Tour Dynam-x features all new technology with control in mind. This ball is a unique piece that will be a great addition to any tournament players bag. This ball was built with tour players in mind, they wanted to have a ball that would give a controllable ball motion that does not deviate from its line very easily. In my mind I feel like this ball was created to give a urethane feel without the ball destroying an oil pattern. From what I have seen from this ball so far I will be able to throw this ball on a variety of patterns, this ball doesn’t do anything spooky. For someone that has a higher rev rate, this ball will allow me to stay further right on more patterns which is something that I am always looking for. I am extremely happy with this ball so far and I look forward to using it in more settings! Go out and get yours today!

It has a very smooth reaction through most of the lane but very strong. I compare this to IQ Tour, but earlier and stronger. Very versatile ball as I am able to throw on fresh house shots, as well as medium to medium heavy oil sport shots. What impresses me the most about this ball is how low it keeps the pins when it hits, creating a lot of pin action. This bowls well for out of box as well as shined up, it is probably the most versatile ball in my bag currently.

    Sleeper ball of the decade!!! Roto Grip coming out with some fire with the new Tour Dynamix! An RG of 2.47, Diff of .026 and and intermidiate of .010 wrapped with the Tour Trax coverstock. What you'll see out of this ball is a very smooth and predictable ball reaction that contiues through the pins. This ball is a asym IQ Tour that is earlier with the same amount of continuation. I have thrown this ball across a variety of patterns and its usually the first ball out of my bag when I am looking for something that is slightly stronger than my symetrical solid options, but not something as strong as somethig like a Reality or Gem. Even on easier shots, this ball blends the over/under better than I have ever seen a ball do it. You need one...or two. NOW!

PAP 5” Over 1/2 up Rev Rate 300. Tilt 20. Rotation 50. Speed at release 17 Review: The new Roto Grip Tour Dynam-X is a very nice rolling addition to the Roto Grip Line. This ball has the predictability you would expect from a “Tour” type ball but the Dynam-X has more motion and drive for me than my IQ Tour Navy. I was able to play different lines with this ball and it is equally useful on house or sport patterns. I feel the asymmetric core contributes to the control aspects of this ball without overpowering the cover. An added bonus of the Tour Dynam-X is that it polishes so easily and it still maintains the predictable roll it had dull at box. It looks great with polish also. We used it at dull box for the video. There are so many good medium type balls coming from the Storm, Global and Roto family you cannot go wrong. Roto Grip lists this ball a bit weaker than I see it, but we all bowl on different conditions and surfaces. I think we will see this ball being used in the tour stops when a bit more motion than an IQ Navy is required. I had my best look with this ball keeping my lines in front of me just inside the friction. The Tour Dynam-X fits between the Hustle USA and the original Gem in my Roto line up. This ball seems to roll nice than make a predictable move at the right time and carries through the pins with great carry. Summary: The Tour Dynam-X should be a tour favorite. The Tour Dynam-X has a bit more pop at the back end than my IQ Tour Navy. This ball could also be used as a asymmetric benchmark solid. Glenn Wendel Storm Pro Shop Staff Video Link:

  • Tour DynamX

    Posted by Brian Hirsch on Sep 25th 2023

    Hey everyone, I'm back with another ball review, and this time it's for the Roto Grip Tour Dynam-X! In 14 pounds this ball is wrapped in TourTrax Solid Cover and comes with A 2000 grit finish and an RG of 2.52, Diff of .026, and an MB of .008. The Tour Dynam-X is the newest ball from Roto Grip and right after throwing this ball, you can tell that this ball is different. The technical numbers of this ball make it a great middle-of-the-bag ball AKA benchmark ball. This ball comes with some surface and at 2000 it blends the lane instead of being too quick to hit all three phases of ball motion. I use this ball later in the night during league when they get wet/dry but really see this ball shining more on the tournament side where you see different lane conditions and oil patterns. This ball takes to surface changes very well and depending on what you are looking for play with the surface to get what you looking for.
