Dating back to the mid-1950’s, there is a reason Roto Grip is often referred to as the “Original High-Performance Bowling Ball Specialists.”
Our latest asymmetrical creation continues that tradition with the development of the RST Core which produces consistent core torque and energy transfer down lane where it is needed most.
From there we formulated the most versatile MicroTrax Hybrid Coverstock to date which produces optimum responsiveness to both oil and friction.
It’s ok, you can thank us later!
MicroTrax Hybrid Coverstock
Our MicroTrax (Micro Nanoparticle Traction) Hybrid Coverstock creates a larger than average footprint in oil, while still providing above average responsiveness to friction down lane thanks to its overall chemical structure. This version of hybrid technology is far and away our most aggressive due to the nanoparticles helping to provide greater peaks and valleys in the overall surface profile.
Bottom line, this coverstock technology just flat out crushes in terms of performance. Featuring a 100% nanoparticle load, this hybrid concoction provides midlane traction and response to friction while maintaining its surface profile over a longer period of time to ensure you get maximum performance each and every time. And just like the hybrid version, the hybrid version displaces oil at the highest rate of any of our pearl covers. Basically, think of it as added forgiveness on those not-so-great shots off your hand.
Engineered for Medium/Heavy to Heavy Oil Conditions
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.
