Translated from Japanese:

From the GEM series, which represents the world's most popular ball, RotoGrip, the "Gem Crystal" is now available.

This time, "Hyper X™ Hybrid Reactive" was used as the cover stock to refine the trajectory stability on the oil. This cover material boasts the second coefficient of friction from the top of the Rotogrip cover material.

Although it is a hybrid, it uses a lot of pearl material and increases its power from the middle of the lane.

The "Defiant™ LRG Core" built into the GEM series causes a strong roll from the front, and the biggest feature of the "Gem Crystal" is that it can be corrected by stabilizing the rotation axis in response to a misrelease, and you can feel the ease of throwing.

Roto Grip 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.
