The original Gremlin became a superstar on the strength of its maxed-out core densities. 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.
The 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.
