Roto Grip RST Black Bowling Ball

Roto Grip RST Black Bowling Ball: Power, Precision & Performance

Looking for a high-performance bowling ball that offers consistent power and precision? The Roto Grip RST Black is the perfect addition to any serious bowler’s arsenal. Building on the success of the popular RST series, this updated design will take your game to the next level with its cutting-edge engineering.

Advanced Pearl Coverstock for Maximum Hook

The Roto Grip RST Black features the all-new eTrax™ (ULTRA-Response version) pearl reactive coverstock. This innovative material is engineered for superior lane length and a highly responsive backend reaction, making it one of the best bowling balls for medium to heavy oil conditions. Compared to previous pearl coverstocks, the eTrax™ Ultra provides a cleaner glide through the front of the lane while delivering an explosive, angular motion when it encounters friction.

Asymmetrical Core for Powerful Pin Action

At the heart of the RST Black is the RST™ (Roto Star Tour) Core. This asymmetrical core is designed to provide a stable, predictable roll through the mid-lane with a strong continuation through the pins. The result is explosive hitting power and impressive pin carry, helping you turn strikes into victories.

Tested and Approved by Bowling Professionals

Roto Grip’s R&D team and professional staff players rigorously tested multiple materials to find the perfect complement to the RST line. The Ultra™ pearl coverstock was the clear winner, chosen for its unmatched performance and versatility. If you’re looking for a ball that provides more length and a sharper backend reaction than the original RST Hyperdrive, the RST Black is the perfect choice.
