CORE TECHNOLOGY: The Rondure™ TOUR-X Core is a precision-engineered modification of the proven Rondure
shape. By manipulating the internal mass densities, we have successfully lowered both the Radius of Gyration and the Differential. This intentional shift provides a highly controllable, medium-flaring asymmetric dynamic, perfectly tuned to deliver the smooth, professional-grade motion demanded by elite players.
COVER TECHNOLOGY: The V-R1™ Hybrid Reactive is an advanced, nano-free formulation designed for a more
aggressive footprint on the lane. By utilizing a precisely engineered 2:1 ratio—blending two parts solid & one
part pearl—this coverstock achieves a potent balance of unadulterated havoc and refined predictability. The
solid components ensure maximum mid-lane traction, while the pearl additive provides more response through the backend. The result is a tour-level coverstock that offers consistent & continuous motion.
PERFORMANCE SYNOPSIS: Engineered specifically for bowlers seeking more overall control and a predictable,
continuous motion throughout the entire lane. The combination of the Rondure™ TOUR-X Core and the
balanced V-R1™ Hybrid Coverstock creates a highly versatile and tunable ball that excels on a wide variety of
oil patterns, making it a staple for any competitive arsenal.
Master the lanes with the Roto Grip Gremlin Tour-X, the disciplined successor to the legendary Gremlin series. Engineered for the competitive bowler who demands a “Tour-ready” look, this ball trades unpredictable “snap” for surgical precision and smooth, continuous motion. Whether you’re navigating league night transitions or a demanding tournament block, the Tour-X is built to keep you in the pocket and at the top of the leaderboard
Features
Rondure TOUR-X Core: We’ve re-engineered the DNA of the original Rondure™ MaxD Core, meticulously adjusting densities to lower the RG and Differential. This creates a stable, centered energy displacement that prevents overreaction at the breakpoint, offering a predictable mid-lane read
V-R1 Hybrid Coverstock: The perfect “middle ground” shell. By blending versatile pearl materials with a solid component, this hybrid technology provides enough teeth to handle oil while maintaining the cleanliness needed to clear the front of the lane with ease.
Engineered for Versatility: This ball excels on Medium to Medium/Heavy oil conditions. It bridges the gap between wet and dry, offering a controlled medium-flare pattern that tames “jumpy” backend responses.
