RotoGrip Gem Crystal (overseas)

Exquisite. Remarkable. Sublime. While these words may capture its essence, we prefer a more fitting label for this masterpiece – the GEM™. Prepare to leave your competitors spellbound, as its stunning aesthetics are matched only by its outstanding performance. This is all thanks to the inner treasure that lies within, the Defiant™ LRG Core – Roto Grip’s most groundbreaking creation with an extraordinarily low RG asymmetrical core. This translates to an unparalleled speed and revolution response, making it our most dynamic asymmetrical core to date.
DEFIANT LRG CORE
Through, thorough studies on flare migration and core tendencies, our focus returned to the Defiant Series of bowling balls. These balls showcased a core that was ahead of its time in terms of flare migration, resulting in a consistent and prolonged motion. After conducting extensive reviews and tests, we discovered that by tweaking the composition of this core shape, we were able to develop an asymmetrical core with unprecedented properties: the DEFIANT™ LRG CORE. This core boasts exceptional speed, unmatched revving capabilities, and formidable continuation, making it the pinnacle of our bowling ball offerings.
