The Evoke Hysteria is here to cause a ruckus. This pearlized powerhouse wasn’t just added to the line—it was turned loose. Designed to create a devastating yet controllable angle on moderately heavy oil, this asymmetric beast fuses the game-changing Overload core with the most adaptable Propulsion cover yet: Propulsion MXV. What does that mean for you? Simple. The Evoke Hysteria isn’t just angular—it’s a weapon that fits more playing styles and lane conditions than ever before.
The insanely tunable Overload core is a game-changer. The most versatile asymmetric core in the MOTIV line, it delivers a deadly combo of low RG, moderate differential, and intermediate diff. It slots perfectly between the Jackal series and the medium oil Pride line—powerful yet controllable.
Here’s the kicker: Ball drillers can fine-tune the differential on this core to fit your game. The Overload Core features the unique ability to lower the differential for less flare, perfect for rev-dominant players who need control. Or crank it up by nearly 20% to unlock massive flare and turn the Evoke into a heavy oil destroyer.
Propulsion MXV = Maximum Versatility. The Propulsion coverstock is already legendary for explosive backend motion in balls like the Primal Rage Evolution, but there are times that a more versatile and controllable pearl coverstock is necessary. Enter the Propulsion MXV Pearl—built for maximum versatility.
This next-level cover digs in for added traction in oil while delivering a slightly slower response to friction for a more controlled backend reaction. Finished at 4000 grit LSS, it’s a benchmark starting point for ultimate customization. Want more length and backend pop? Add polish. Need earlier read and smoother motion? Scuff it up. The choice is yours.
Bottom Line: The Evoke Hysteria is your unfair advantage. Dial it in to dominate the lanes and shatter all limits!
Since their conception back in 2016, the Hustle Series of bowling balls has provided outstanding performance above and beyond the retail price. From the 34th sanctioned 900 Series by the Hustle™ INK, to countless TV appearances over the years on both the PBA & PWBA Tours. The various versions of Hustle’s have provided consistent reactions time and time again.
And while the inner Hustle Core has remained the same since day one, it’s the different variations of the VTC™ (Versatile Traction Control) Coverstock – Solid, Pearl & Hybrid, that have kept this line viable on those Light to Medium Oil conditions for every level of bowler from the first timers, all the way up to the pros.
After countless months of research and development, and after multiple tests and discussions with players of all skill levels, the Roto Grip ROCKSTAR provides a new motion and reaction for both the competitive player ranks and the advanced player ranks to shred and rock on those Medium to Heavy Oil Conditions.
Offering new state-of-the-art technology in both the coverstock material and weight block shape design, the ROCKSTAR was developed to provide greater versatility on more oil conditions and lane surfaces than previous HP3 level balls since there have been plenty of advancements in the world of lane maintenance and lane surfaces in recent years.
The new NanoStar™ coverstock material is Roto Grip’s latest nanotechnology remix. This union of nano particles mixed with new chemistry provides similar traction in the midlane to that of our legendary MicroTrax™ material. However, the difference you will easily see is that the NanoStar™ material does not dig into the lane as early as MicroTrax™, it generates more responsiveness to friction down lane in terms of nanotechnology materials. In other words, breaking it down a little more for you… NanoStar is not as early as MicroTrax, and it’s not as clean and responsive as our eTrax™, eTrax PLUS™, or eTrax ULTRA™ materials. Therefore, it fills the gap between MicroTrax™ and eTrax™.
Showcased at the center of it all you will find our newly developed weight block shape that is destined for greatness, known as the ROCKER Core. Its authentic shape encapsulated in A.I. Core technology provides a more centralized rotation plane to better provide more continuation through the pin deck. As always, the Roto Grip team of R&D rockstars aim to develop weight block shapes that perform for bowlers of all skill levels not just the ones you see on TV. Meaning, the ROCKER Core is no different, it was designed for the masses. Let’s just say, the combination of amplified power and amplified motion results in sheer amplified awesomeness.
So, if you are indeed ready to rock, then look no further, ROCKSTAR is here and ready to make you famous!
The Level bowling ball is the groundbreaking debut of the Lab Series, a line designed to redefine performance through limitless innovation. Wrapped around the new Level is a new coverstock material that has physical properties never seen before in the bowling industry. This makes the Level a great choice when consistent, continuous, predictable ball motion is needed.
Wrapped in the revolutionary RPM (Regenerative Polymer Matrix) coverstock, the Level offers oil absorption rates never seen before, delivering consistent ball motion with less response to friction. Unlike traditional coverstocks that lose surface integrity over time, RPM maintains its surface profile for a predictable reaction on every shot. Built for bowlers who demand top-tier performance, the Level delivers unmatched consistency, control, and innovation for the modern game.
At its core is the Equalizer A.I. Core™, a tall, low-density weight block engineered to deliver a higher RG for a smoother, more controlled transition without sacrificing differential or consistency. This precision design ensures unparalleled repeatability and shot-to-shot reliability.
The most crucial part of the design is the overall density of the weight block itself. A lighter density was chosen in order to increase the RG value so the Equalizer™ A.I. Core™ would take longer to respond to friction. Lighter densities raise the RG, but they simultaneously decrease the total differential. Traditionally, a shape of this design would require a higher density slug to increase differential into a zone that would be more manageable for a majority of bowlers. The cuts towards the middle of the shape combined with the increased overall length of the weight block create more differential than would normally be seen with a shape of this size and density.
The Hy-Road 40 celebrates four decades of Storm innovation by continuing the legacy of one of the most trusted names in bowling. At its core lies the legendary Inverted Fe² Technology—Storm’s most successful weight block design—delivering unmatched energy retention and dynamic hitting power. Wrapped in the successful A1S Pearl coverstock—first debuted on the Equinox and known as one of the fastest oil-absorbing materials in our lineup—the Hy-Road 40 maintains a consistent reaction shot after shot, especially in heavier conditions where oil buildup can compromise performance. The Hy-Road 40 is a tribute to where we’ve been—and a bold step toward where you’re headed.
