Here comes the "boom" with Roto Grip TNT!

Explosive new ball motion is here in the newest 2023 Roto Grip release! Featuring the new Torpex symmetric core, this low RG/high diff shape will help create a strong overall hook motion, while still allowing forgiveness for all different bowling styles.

Wrapped in the eTrax PLUS solid reactive coverstock, finished at 2000-Grit Abralon, TNT will light up medium to heavy lane conditions and hit the pins with devastatingly strong traction.
Here's what Roto Grip has to say about TNT:
Engineered to create more torque and overall explosive power than all the low RG symmetrical balls before it, the TNT is here to blow racks up and take names. This ball will have your opponent's calling the bomb squad for help.


The early motion from the TNT really blends out oil patterns and provides a smooth motion off the dry. It was best for straighter angles on the fresh and in early transition.


The TNT's smooth motion limits its effectiveness when opening up the lane in transition. Steeper launch angles require much lower ball speeds to be effective, and more angular balls are a better option later in transition.

Overall Summary

The TNT is one of the earliest and smoothest motions in the current Roto Grip line. Its low RG core design and dull solid coverstock get it started quickly, providing a controlled motion at the friction.
