Roto Grip Gremlin Tour X Bowling Ball

The legend grows, but the footprint gets more precise. Roto Grip is proud to introduce the Gremlin TOUR-X, a ball designed specifically for those who demand “professional-grade motion” without the unpredictability.

When the lanes get tough and the original Gremlin is a bit too “wild,” the TOUR-X steps in to provide the control, predictability, and punch you need to stay at the top of the leaderboard.

Engineering the “Tour” Motion

We didn’t just tweak the original; we re-engineered the DNA of the Gremlin series to favor control and versatility.

The Rondure™ TOUR-X Core: By meticulously adjusting the densities of the original Rondure™ MaxD Core, we’ve lowered both the RG and the Differential. This creates a more stable, centered energy displacement that prevents the ball from overreacting at the breakpoint.

V-R1™ Hybrid Coverstock: This proven hybrid shell offers the perfect “middle ground” traction. It provides enough teeth to handle oil while maintaining the cleanliness needed to clear the front of the lane.

4000-Abralon® Finish: Sanded to a smooth 4000-grit, the TOUR-X offers a matte finish that reads the mid-lane early enough to be predictable, but late enough to retain maximum energy for the pocket.

Why the Gremlin TOUR-X?

In the modern game, “more hook” isn’t always the answer—better hook is. The Gremlin TOUR-X is built for the competitive bowler who needs a ball that blends the wet and the dry. Expect a medium-flare pattern that keeps your transitions smooth and your carry high.

The Bottom Line: If you loved the shape of the original Gremlin but want a more disciplined, “Tour-ready” version for league nights or tournament blocks, the Gremlin TOUR-X is your new go-to.
