The Roto Grip Wicked Gremlin takes that iconic Gremlin Series to a more aggressive level, pairing the same proven engine with a refined, nano-free solid cover built for controlled heavy-oil traction.\n\nThe Wicked Gremlin keeps the asymmetric Rondure MaxD Core, the high-density block that powered the original Gremlin, and wraps it in the new G-R1 Solid Reactive coverstock at a 2000-grit finish, in a bold Citrine, Red, and Purple cosmetic. The result is a grippy, high-friction footprint without the over-aggressive bite of its predecessor: more mid-lane traction with a smoother, more continuous transition through the backend. It is the high-performance HP3 piece in Roto Grip's lineup. The Wicked Gremlin is part of one of the deepest new-release seasons in years, which you can see in our 2026 new bowling balls roundup.\n\nUnderstanding the Roto Grip Rondure MaxD Core and Roto Grip G-R1 Solid Reactive\n\nRoto Grip built the Wicked Gremlin for controlled traction on medium-heavy oil. Specifically, the asymmetric Rondure MaxD core uses maxed-out densities to read the mid-lane strongly and keep driving, while the new G-R1 Solid cover delivers a high-friction, grippy footprint engineered as a refined, nano-free alternative to the more aggressive V-R1. As a result, you get a predictable mid-lane read and a smooth, continuous transition rather than an over-aggressive, jumpy bite, which is exactly what makes it handle fresh house shots and transitioning tournament conditions wickedly well. The full per-weight specs are listed below.\n\nThe Maxed-Out Asymmetric Engine Behind the Original Gremlin\n\nAt the heart of the Wicked Gremlin is the asymmetric Rondure MaxD Core, the same maxed-out weight block that propelled the original Gremlin to superstar status. At 15 lb it measures RG 2.50, a strong .058 differential, and a .010 intermediate differential (mass bias), numbers that produce heavy flare and a strong, continuous, hard-driving motion. The maxed-out densities are the key: they let the core read the mid-lane early and keep storing energy deep into the pattern instead of rolling out.\n\nThat strong, continuous motion is what makes the Wicked Gremlin a true heavy-oil piece. The Rondure MaxD core delivers an early, powerful read and keeps driving through the pins, and the high differential creates the flare needed to clear medium-heavy volume. It is an aggressive engine that, paired with the right cover, stays controllable rather than jumpy.\n\nA Nano-Free Solid Built for Controlled, Continuous Traction\n\nWhat separates the Wicked Gremlin from its predecessor is the new G-R1 Solid Reactive coverstock. The G-R1 (GRIP-Response) shell delivers a high-friction, grippy footprint, but it was engineered as a refined, nano-free alternative to the more aggressive V-R1, so it reads strongly without the over-aggressive bite. Finished at 2000 grit, it provides a predictable mid-lane read and a smoother, more continuous transition through the backend. As a result, the Wicked Gremlin gives you heavy-oil traction with controlled, continuous motion, which sets it apart from other nano-free solids.\n\nWicked Gremlin Specs\n\nRG and differential vary by weight. Specifications provided by the manufacturer.\n\nWho This Ball Is Right For\n\n✓Tournament Players: An early-reading, controllable heavy-oil solid that handles fresh and transitioning patterns with continuous drive\n\n✓Higher-Rev Bowlers: The maxed-out Rondure MaxD core rewards revs with strong flare and a smooth, hard-driving backend\n\n✓League Bowlers: A strong benchmark solid for medium-heavy house volume that reads the lane the same way shot after shot\n\n✓Control-Minded Stylists: The nano-free G-R1 cover grips without jumping, giving traction with a controllable, continuous shape\n\nGood to Know Before You Buy\n\n·Strong, aggressive motion: This is a high-flare piece built for traction. If you want a controlled, lower-hook reaction, a lower-differential ball will suit you better.\n\n·Ships sanded for traction: The 2000 Grit Abralon finish is built to grip in oil. Polish it for more length when the volume drops.\n\n·Asymmetric layout sensitivity: Layout choices shift the reaction more than on a symmetric ball. Match the pin and mass bias to your game with your pro shop.\n\n·Colors vary: Actual colors vary somewhat from the photos shown; no two balls come out of the mold exactly alike.\n\n·Tiny pit holes are normal: A few tiny pit holes in the coverstock are a normal part of the manufacturing process.\n\n·Sold undrilled: Ships without finger holes, so it can be fitted to your hand and span.\n\nBowlersMart Tips: Where the Wicked Gremlin Fits in Your Roto Grip Arsenal\n\nWhere It Fits in Your Arsenal\n\nIn the Roto Grip lineup, the Wicked Gremlin is the controlled heavy-oil solid you throw on the fresh. Where an aggressive asymmetric can read too early and over-hook, the Wicked Gremlin grips strongly but transitions smoothly, keeping its motion continuous. It pairs naturally below your strongest asymmetric and above a pearl, giving you a benchmark traction piece for medium-heavy volume.\n\nSurface Adjustments\n\nThe 2000-grit finish is a traction setup out of the box. Raise the grit or polish for more length when the oil drops, or refresh the 2000 surface to restore traction. Have surface changes done at your pro shop for an even, consistent finish.\n\nCoverstock Care\n\nSolid covers absorb oil over time, which dulls the read. Wiping the Wicked Gremlin down after every set and deep cleaning periodically keeps its strong mid-lane traction consistent over the life of the ball.\n\nEarn points on every Roto Grip purchase through the Striking Rewards loyalty program.
