Behind the X-3 name…
Founded in the early 1950s, Roto Star emerged as the frontrunner in the realm of high-performance bowling balls, later known as Roto Grip. Their expertise in crafting top-notch bowling balls earned them a renowned reputation in the industry.
Because of this industry leading mantra, and with the latest creation of the Roto Star Tour Core, it only made sense to go back in time to recapture the vibe and pay homage to those balls that set the standard for technology and development.
Overseas bowling balls are approved for all sanctioned USBC league and tournament play, but may not approved for PBA competition. Please check all rules and regulations before competition.
