CORE TECHNOLOGY: The Morph-Wing Core returns as a dynamic asymmetric masterpiece designed to evolve. This core transforms unlike any other asymmetric shape on the market; its unique "wing" geometry allows for massive displacement during the drilling process. By strategically removing mass from the wing, the core numbers shift dramatically, allowing for a completely customized flare pattern and motion based on the specific transformation of the core shape.
 
COVER TECHNOLOGY: MicroTrax™ Pearl Reactive... Evolution meets friction. The TRANSFORM Pearl features our high-performance MicroTrax Pearl Reactive coverstock, which is 100% nano-loaded. Unlike traditional pearls that can sometimes "squirt" through heavy oil, the nano-particle additives create a significantly stronger footprint and enhanced traction through the mid-lane. This ensures the ball maintains its path in oil while still delivering the aggressive, crisp response to friction that bowlers demand down-lane.
 
PERFORMANCE SYNOPSIS: Building on the versatility of its predecessor, the TRANSFORM Pearl offers a lethal combination of mid-lane stability and backend recovery. While the core provides unmatched tunability for any arsenal, the 100% nano-loaded cover ensures you don’t have to sacrifice "teeth" for "turn." It is the ultimate solution for bowlers needing a ball that digs through the slick but snaps hard when it sees the dry.

    Transform Review by Kyle, Joel, & Dean Johnson

    Posted by Kyle, Joel, & Dean Johnson on Aug 3rd 2026

    Roto Grip Transform Coverstock: MicroTrax™ Pearl Reactive with Power Edge Core: Morph-Wing™ (Asymmetrical) Color: Red/Cherry/Shadow Review: There was a LOT of information on the original Transformer release so we hope you didn’t get lost in the sauce because this core design is definitely a game changer for SPI. This is the second cover formula on the first intentional shaped core with special drilling designed to change the dynamics of how the ball will react on the lanes. Our style: tweener, 350-375 revs, 16.5mph, layout of choice is 4x4x2 (pin is above bridge). The big question is leave the wing or take the wing out? This really depends on what kind of shape you want. If an earlier, smoother motion throughout the lane is warranted, then you will likely drill out the wing. If you want a later, more continuous look through the pins, then you will likely want to leave the wing. This ball with the wing drilled out rolls a lot like an Exotic Gem. Big engine that is very forward rolling, especially with the nano-loaded coverstock. You can really manipulate the shape and blend patterns well. This ball with the wing in is very different and continuous. Like an Ion Max Pearl that is slightly more continuous. You really can tell the difference when that wing flips and that weight block drives through the pins. This is a really cool second installment release and we hope that people aren’t scared by the amount of information put out.

    Transform Pearl

    Posted by Keith C on Aug 3rd 2026

    Roto Grip Transform Pearl – Ball Review Layout: Storm VLS 5 × 4 × 1 Style: Right-Handed Ball Speed: 16 mph Rev Rate: 300 RPM Axis Tilt: 16° Axis Rotation: 73.5° PAP: 5¼” over, 7/8” up Lane Condition: Typical 41’ House Shot The Roto Grip Transform Pearl has quickly become one of the most versatile transition pieces in my tournament and league arsenal. Drilled with a 5 × 4 × 1 Storm VLS layout, it gives me the ideal combination of easy length, a defined but controlled backend motion, and outstanding continuation through the pins. On a typical 41-foot house shot, the Transform Pearl clears the front of the lane effortlessly while maintaining enough midlane stability to prevent the over/under reaction that many pearl asymmetrics can produce. With my 300 RPM rev rate, 16 mph ball speed, 16° of axis tilt, and 73.5° of axis rotation, the ball stores plenty of energy before making a strong, continuous move through the breakpoint. The backend motion is best described as strong and continuous rather than sharp and sideways. The asymmetric core gives the ball enough stability to read the lane before changing direction, resulting in a predictable shape that blends wet/dry conditions exceptionally well. Even when I open my angles during transition, the Transform Pearl retains enough energy to drive through the 8-9 pin area and produce excellent carry. The 5 × 4 × 1 VLS layout complements my release perfectly. The longer pin-to-PAP distance promotes excellent energy retention, while the smaller VAL angle creates a quicker response to friction without becoming uncontrollable. I found I could stay aggressive with my target moves as the lanes broke down, knowing the ball would recover consistently while maintaining continuation through the deck. This is the ball I reach for once stronger solids begin reading too early but I still need a defined move downlane. Instead of sacrificing control for backend motion, the Transform Pearl delivers both. In the Bag Here’s where the Transform Pearl fits within my current SPI arsenal: Viking Conquest The Viking Conquest bridges the gap between heavy-oil solids and cleaner asymmetric pieces. It provides a strong midlane read with excellent continuation and is ideal when the Harsh Reality begins reading too early but I still need control in the oil. Transform Pearl This is my transition ball. As the fronts begin to hook and I need more length with a stronger move downlane, the Transform Pearl shines. It allows me to migrate left, open my angles, and continue creating entry angle without sacrificing predictability. On a typical 41-foot house shot, this is often the ball that stays in my hand the longest because it blends the transition so well. Roto Grip Hyped Up The Hyped Up gives me easier length and a smoother, more benchmark-type motion than the Transform Pearl. When the pattern gets drier or I need to square up and keep my angles in front of me, the Hyped Up becomes the better option. It offers excellent control while still providing enough recovery to carry from deeper inside lines. Best Uses • Medium to medium-heavy house conditions • Transition games during league and tournament play • When stronger solids begin reading too early • Creating more entry angle without sacrificing predictability • Opening up the lane while maintaining continuation through the pin The Transform Pearl can be one of the most valuable spots in your arsenal. It provides the clean front-lane motion I want after transition while still giving the confidence of an asymmetric core that won’t overreact to friction. It creates a predictable, continuous motion that produces outstanding carry on a typical 41-foot house shot. For bowlers looking for a pearl asymmetric that combines easy length, strong continuation, and exceptional control, the Transform Pearl is an outstanding choice. Move in and get comfortable playing the transition. #SquadRG #Stormnation #Stikingworldwide

    Transform Pearl!

    Posted by Joshua L. Shoemaker on Aug 1st 2026

    The Transform Pearl is Roto Grips newest HP5 bowling ball. The Transform Pearl features the same Morph Wing core found in the Transformer but is now wrapped in Micro Trax Pearl. The Transform Pearl for me is easier to shape than the Ion Max Pearl. The Transform Pearl will be the perfect piece to bridge the gap between balls like the Alpha Crux and Vengeance Returns. The Transform Pearl is now available from any Storm VIP Pro Shop! Review Video: https://youtu.be/0qSlP9RLw6M?si=eaeErUYs1l4_IrkS

    Transform Again, This Time With Pearl

    Posted by Darren Wong on Jul 31st 2026

    The Roto Grip Transformer introduced by Storm Products at the beginning of the year was an advance in core dynamics technology to manipulate ball motion utilizing a core shape with a morph wing which could be drilled in multiple ways to “transform” and dial in ball motion. The advancement in core design was great, but I felt the cover around the Morph-Wing in the original Transformer was maybe a little too weak (VR-1 solid). Roto Grip has released the Transform Pearl with a stronger coverstock- MicroTrax Pearl Reactive. Even though it’s pearl, the MicroTrax cover is stronger than VR-1 because it features nano-particles mixed evenly throughout the entire coverstock making it the most aggressive pearl material SPI manufactures. So I think this cover is a better match with the Morph-Wing Core. MicroTrax cover was on the RST-X1 (one of my personal favorites) and the Optimum Idol. As we learned with the original Transformer, the Morph-Wing Core RG is on the higher side at 2.51 for the 15# which also helps it clear the fronts. The diff is 0.051 and PSA dif is 0.015 which are both in the medium range. But what makes the core special are those wings. If you leave them in tact, it creates torque induced precession which essentially pulls the ball from right to left for a right hander. If you drill through the wing, then it removes that torque induced precession and acts like most other balls/cores. Since I want to take advantage of torque induced precession uniqueness offered by the Transform Pearl and because I use my thumb, I drilled mine to miss the wing (4 3/4 x 4 x 2). I haven’t had a chance to throw this one a lot, but I like what I see the couple times I’ve thrown it on a house pattern (shot 278 first game out of the box with it). It definitely continues down lane and drives through the pins which really helps my pin carry. The pearl cover with the nano-particles does provide that good combination of not reading too early so it has some free push, but it does not over-skid or hydroplane through the front. If you are looking for a middle of your bag ball, the Transform Pearl would be a great choice especially because you have options to achieve the desired ball motion. If you are looking for strong continuous downlane motion, leave the wing intact. If you want a smoother ball motion, hit the wing. I would definitely recommend that Transform Pearl and you should get it drilled by your local Storm VIP Pro Shop to ensure it’s laid out properly for what you want to achieve.

    wow amazing reaction

    Posted by Todd Pawlak on Jul 31st 2026

    The new Roto Grip Transform... All I can say is WOW!! This ball rolls pretty good and looks really good going down the lane. A lot of back end for sure. Mine is drilled pin up, I liked how it rolled out of the box, after putting a few games on it, I decided to hit it with a 4000 pad just to get the ball to hook a little sooner and I liked it a little more. Don't be afraid to adjust your bowling ball surface to make it fit how you roll the ball, we are all different for sure. for me, It even reacted pretty good on the longer oil patterns as well, so its pretty versatile for sure. Straight up with some back end reaction, or playing a little deeper, yeah this ball will work for sure.

    Roto Grip Transform Pearl Ball Review by PJ Haggerty

    Posted by PJ Haggerty on Jul 31st 2026

    There’s one thing that our gurus in Utah continue to impress bowlers with… and that’s technology. When the original Transformer came out, the Morph-Wing core was introduced and it was something that’s never been seen before. It taught bowlers and pro shop operators how to change the physics of the core by drilling into the ‘wing’ or missing the ‘wing’ and how that could drastically change the way a ball rolls. I thought the original Transformer was excellent, and after throwing the Transform Pearl, I believe it’s just as good. With the new Transform, the core didn’t change, but the coverstock did. This ball features the MicroTrax coverstock which provides more length and more pop at the end of the pattern. I’ve drilled one so far and really like it. My goal was to use this after some of the earlier-reading balls have done their job (Vengeance, Viking Conquest, etc.) so I mapped this one out as 5.5 x 5 x 3. This puts the pin above my middle finger and the mass bias just to the right of my thumb. I haven’t touched the surface either. As expected, this ball isn’t necessarily something I’ll use on the fresh, but it’s definitely a ball I’ve transitioned into once the balls listed above have done what their supposed to do. Go drill one!

    Transform Pearl

    Posted by Todd Benner on Jul 29th 2026

    The new Roto Grip Transform Pearl features the same Morph Wing core from the Transformer but wraps it in the hugely successful Micro Trax pearl coverstock finished with Power Edge. At 15 pounds the Transform Pearl has an RG of 2.51 with a differential of .051 and an intermediate differential of .015. The Morph Wing core offers a lot of different reaction options depending on the drilling. I chose to keep the wing intact and not drill into it. The combination of the core and the Micor Trax pearl make this ball a huge success. The coverstock gets through the front part of the lane but really reads the midlane and very rarely, if ever, misses the spot at the breakpoint. Speaking of breakpoint, for an asymmetrical pearl, this ball has a very strong and continuous backend motion. I found this ball really blends out the wet/dry league pattern like a champ. The cover is strong enough to read in the oil and clean and responsive enough to recover on those errant shots that hit the dry too soon. With league season fast approaching, this is a ball all bowlers will want to add to their bag!

    Roto Grip Transform Pearl

    Posted by Dannial Cohen on Jul 28th 2026

    Roto Grip Transform Pearl The Transform Pearl uses the morph wing core which was used in the orginal Transformer wrapped with the microtrax Pearl coverstock. Microtrax Pearl coverstock features nano particles in the coverstock which creates a stronger footprint creating more reaction in the midlane and backend. Transform Pearl is a asymmetrical core RG 2.51 Diff .051 Intermediate diff .015 Finish is poweredge polish I drilled my Transform Pearl 5x4.5x2 using the Storm VLS layout system which gives me length through the heads with strong response to the friction. The Transform Pearl will be a great compliment to the orginal Transformer You can start with the Transformer on fresh oil then once the lane transitions you can go to Transform Pearl for more backend with a strong continuation

    Transform

    Posted by Carlos Torrero on Jul 28th 2026

    The Transform Pearl has been a great ball for me with the 4.5 × 4 × 2 layout. It gets through the front of the lane really clean and has a strong, smooth move when it finds friction. It's become one of my favorite balls for transition because it lets me open up my angles while still carrying the corners.

    The Transform Pearl!

    Posted by Rick Klimowicz on Jul 27th 2026

    Transform Pearl • Roto Grip • HP5 Series Coverstock • MicroTrax Pearl • Finish Power Edge Core • Morph-Wing Core Weight •. 15 lb. RG • 2.51 Differential • .051 PSA •.015 Layout • 4 ½ x 4 1/8 x 2 1/8 Tester PAP • 5” R, 5/8” D Tester Axis Tilt • 11° Tester Rev Rate • 300 Test Pattern • 42’ THS (Typical House Shot) • Modified, Kegel Stone Street Roto Grip takes its state-of-the-art technology to a whole new level with the release of the Transform Pearl. The Transform Pearl starts with Roto Grip’s uniquely designed, high-flaring Morph-Wing Core, originally found in the Transformer. Roto Grip then wraps that Morph-Wing technology with its superior nano-gripping MicroTrax Pearl coverstock. This combination proves the Transform Pearl is a great choice for those seeking a balance of traction and power! So, let’s take a closer look at the Transform Pearl and where it can fit in your arsenal. The Morph-Wing found in the Transform Pearl rolls and reacts very similarly to the original Transformer. I drilled my Transform Pearl in the pin-up position and found it had an incredible amount of flare as it made its way down the lane. As a straighter bowler, that strong flare gave my slower-rev hand a much stronger, more powerful entry angle, bringing some tantalizing results through the pins. The Morph-Wing core stood up brilliantly for me when the Transform Pearl exited the pattern. That hard-rolling motion created not only a lot of swirling pin action but also a ferocious continuation to carry those light hits I tend to have. So, there is no doubt the Morph-Wing core will bring results. However, to get the most out of the Morph-Wing Core for your style of bowling, I highly suggest you talk with your Pro Shop operator in depth about where and how to manipulate the Wing to suit your game best. The Morph-Wing is uniquely designed; why not drill it that way to boost your game! The MicroTrax Pearl Coverstock has the potential to suit many bowling styles. However, I found that the MicroTrax Pearl took a bit of getting used to for my game. I loved how the MicroTrax grips in the mid-section of the lane with excellent biting traction, and the Transform Pearl certainly maintains a smooth roll throughout its motion down the lane. However, with my challenged rev rate and the factory Power Edge Finish, the Transform Pearl was a bit squirrely off the pattern on a fresh THS. Further, with the factory Power Edge Finish, as the night went on, my Transform was a bit too over-responsive to friction as it came off the pattern, making it a bit jumpy. So, I decided to change the surface on my Transform Pearl to 2000-grit Abralon with a light Power Edge finish, and it gave my Transform a whole new look to fit my particular game! I found that with the correct surface for my straighter, low-rev hand, the Transform came alive. I had that smooth, gripping traction in the mid-lane I liked, and now I also had a clean, predictable motion off the pattern I could depend on, whether it was a fresh THS or the transitioning conditions I tend to see in late game two and beyond. So I would suggest taking the time to tweak the surface of your Transform Pearl to fit your game. Like the Morph-Wing, to make the most of your Transform, tweak the MicroTrax Pearl to fit your game and conditions. I believe it will certainly bring results. In closing, the Transform Pearl is an excellent new release from Roto Grip with a special twist that many bowlers will enjoy. That twist starts with the unique Morph-Wing Core design, which lets you customize drilling to match the reaction you want, and the nano-based MicroTrax Pearl coverstock, which lets you tweak the surface to get the most balance from the grip and flip the MicroTrax can deliver. So, stop into your local Storm VIP Pro Shop today and talk with your Pro Shop operator to get the maximum striking power from your Transform Pearl. The Transform Pearl is worth it!
