Description (merchant text, shortened)
A Maxed-Out Pearl Built for Length and a Continuous Backend
About the Gremlin
The Roto Grip Gremlin is the pearl that started the Gremlin Series. It pairs a maxed-out version of Roto Grip's asymmetric Rondure core with the nano-free V-R1 Pearl Reactive coverstock to deliver clean length through the front of the lane and a strong, continuous response off the dry. It is built for bowlers who want a pearl that reads later and keeps driving rather than jumping.
Roto Grip's R&D lab pushed the Rondure core to its limits for the Gremlin, raising both the RG and the differential to the highest values that shape has ever carried. The result is the longest, most continuous motion in the family: a pearl that lets you move deeper on the lane and still comes around the corner, complementing your stronger asymmetric solids when the heads start to open. Finished at Power Edge polish in a Plum, Raisin, and Tanzanite cosmetic, it handles medium to medium-heavy oil with length and forgiveness.
Understanding the Roto Grip Rondure MaxD Core and Roto Grip V-R1 Pearl Reactive
Roto Grip built the Gremlin around length and continuation. Specifically, the maxed-out Rondure MaxD core carries the highest RG and differential the shape has ever had, so the ball revs up later and stores energy deep into the pattern for a strong, continuous finish. The nano-free V-R1 Pearl Reactive cover, polished at Power Edge, pushes easily through the front of the lane, then responds to friction down-lane without getting out of control. The full per-weight specifications are listed below.
A Maxed-Out Asymmetric Core for the Longest, Most Continuous Motion in the Gremlin Family
At the heart of the Gremlin is the asymmetric Rondure MaxD core, a maxed-out version of Roto Grip's proven Rondure shape. At 15 lb it measures RG 2.50, a strong .058 differential, and a .010 intermediate differential (mass bias). Roto Grip's R&D lab changed the densities of both the block and the bottom slug to push the RG and the differential to the highest values this core has ever carried, which is what gives the Gremlin its length and its big, continuous backend.
That maxed-out shape is the whole story. A higher RG means the ball revs up later and saves its energy for the back of the lane, while the strong differential delivers the flare to clear the oil. Together they produce a pearl that pushes long through the fronts and then makes a strong, continuous move: more room for error than a sharp, jumpy reaction, and exactly the shape you want when you need length with recovery.
