With roots dating back to the mid-1950s, Roto Grip has earned its reputation as the “Original High-Performance Bowling Ball Specialists.” Keeping this legacy alive, our newest asymmetrical creation introduces the RST Core, delivering consistent core torque and optimal energy transfer precisely where it matters, down the lane. Experience the true essence of precision and power with Roto Grip.
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.
XtremeTrax Solid Coverstock
Derived from countless hours of mixing, formulating, and testing, the Xtreme Traction (XtremeTrax™) material pushes us into boundaries of scientific chemistry. We started with the base materials of our MicroTrax™ coverstock and went down a new path in terms of chemistry by adding different chemicals which in turn created “chemical charges” to the nano-particles, thus making a material that not only digs in on heavy oil, but also provides more responsiveness and reaction down lane than traditional nano materials.

Roto Star Tour (RST) Core
Professional bowlers like to see continuous motion down lane with minimal deflection as the ball enters the pocket due to their rev rates usually being on the higher side. This logic was the basis of development by the R&D team as they looked to create a core that would maintain dynamics after drilling in order to maintain a higher level of core torque down lane. The larger mass at the base of the core does indeed create that. Especially since when drilled, the thumbhole will always end up near the bottom of the void area not to affect the bottom mass of the core all that much. Thus, making this core a “Tour Level” type core design.
