- From the manufacturer
Brilliant. Extraordinary. Magnificent. Call it what you will, but we prefer to call this beauty exactly what it is, a GEM™. Not only will its breathtakingly good looks mesmerize your competition, but its overall performance will as well thanks to the inner treasure known as the Defiant™ LRG Core - (the lowest RG asymmetrical core Roto Grip has ever created.) Which means this is by far the fastest revving asymmetrical core we have ever produced. And well, we couldn’t just stop there, so we wrapped this monstrosity of a core with the most aggressive solid coverstock we make known as MicroTrax™ Solid Reactive. Making this ball dazzle on those Heavier Oil Conditions.
