The Gremlin Tour-X pairs Roto Grip's V-R1 Hybrid Reactive coverstock, finished at 4000 Abralon, with the asymmetric Rondure Tour-X core. At 15 pounds the core measures a 2.48 RG, a .034 differential and a .011 intermediate differential, per the manufacturer's specs. That moderate differential gives roughly 3 to 4 inches of track flare.
