The Gremlin Tour-X pairs Roto Grip's re-engineered Rondure Tour-X asymmetric core with the V-R1 Hybrid Reactive coverstock at a 4000 Abralon finish. At 15 lbs it carries an RG of 2.48, a .034 differential, and a .011 mass bias - moderate numbers tuned for a smooth, controlled roll rather than a sharp, unpredictable flip. The hybrid cover reads the midlane for traction while staying clean enough through the front to trust on a wide range of conditions. It's built as a true benchmark piece: strong enough for medium-to-heavy oil, but predictable enough to be the ball you keep coming back to. It ships in a Blue/Grey/Purple colorway with no added scent.
