“Purple Gem” is newly released from the hot topic gem series. This product, reminiscent of the original “Gem”, is a ball that is resistant to oil, bends, and has a pin fly that overturns the conventional wisdom.
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.
MicroTrax Solid Coverstock
The MicroTrax (Micro Nanoparticle Traction) Coverstock offers the optimum balance of midlane traction and responsiveness to friction thanks the blend of nanoparticles throughout the coverstock. This formulation maintains its surface profile texture longer to ensure you get maximum performance while displacing oil at an above average rate compared to other coverstock materials on the market today.
Engineered for Medium/Heavy to Heavy Oil Conditions
Defiant LRG Core
Sometimes evolution can spark new life into technology from yesteryear. Such is the case with our latest introduction to the HP4 Line of balls. With recent more in-depth studies of flare migration and core tendencies we circled the wagons back to the Defiant Series of bowling balls which featured a core ahead of its time regarding flare migration in order to create a longer constant motion. Upon further review and testing, we found that by altering the composite of this core shape, we were able to create the fastest revving, strongest continuing, lowest RG asymmetrical core we have ever offered in the history of ever now known as the DEFIANT™ LRG CORE.
Originally introduced in the GEM, the Defiant LRG Core has brought style, pizzaz and honor scores to bowlers of every skill set around the globe. Thanks largely in part to the density composition of this core, it sets the standard as the fastest revving, strongest continuing, lowest RG asymmetrical core across our lines. So, if strong and continuous is what you are in the market for, then look no further than this part right here. No matter your style or your number of revs on the ball, this core will get into a roll and keep rolling every single time.
