Roto Grip Gem Bowling Ball

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.

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.

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.

    I am looking for a 14 lb. Ball for oily lanes. Ian 70 years old and like to play with 2nd arrow but struggling with fresh oil on our house lanes. I throw between 13-14 mph with low to medium revolutions. I now have a Hammer Statement solid 15 lb and a Brunswick Prism solid 14 lb
    The 14 lb moves better for me .
    I average 185-190
    What ball would you suggest?
    I just started bowing again the last 3 years after a 50 year layoff
