Roto Grip Attention Star S2 Bowling Ball

Roto Grip Attention Star S2 Bowling Ball

Building on the overwhelming success of its predecessor, the Roto Grip Attention Star S2 Bowling Ball takes precision and lane control to a whole new level. Designed with pro-level insight and innovation, the S2 features the same game-changing Momentous™ AV Core with A.I. Core Technology that made the original a standout, now paired with a brand-new eTrax™ PLUS Hybrid Reactive coverstock for enhanced midlane grip and powerful backend recovery.

Finished with 2000 Grit Abralon, the hybrid shell offers earlier read than the original pearl while maintaining the explosive continuation that bowlers loved. The S2 reads the midlane with control and rolls through the pins with authority—ideal for medium to heavy oil conditions where predictability and power matter most.

Roto Grip’s R&D team carefully tuned the density inside the Momentous asymmetrical block, enhancing energy retention and release at impact. With an RG of 2.48, differential of .049, and a mass bias strength of .017, the S2 is a strong, high-flaring option that delivers confidence with every roll.
