The Silver Streak/R is Roto Grip's latest release of the performance proven Rotary Core. This revolutionary design continues to be the most versatile and successful ever created.

Sure grip pearl reactive surrounds this core creating increased length through the front part of the lane, and an explosive backend motion.
