Rotogrip Vintage Gem

The Gem series is born wearing the first running cover stock "eTrax Plus Pearl Reactive" for the first time in a long time. Rolling and running, stable trajectory and controllability, large arc-shaped bends, all types of players can use the best performance ball "VINTAGE GEM" no matter which line they use.

There will be slight release deviations in any class of bowlers, but this "Defiant LRG Core" will compensate for them and lead to high scores.

Moreover, this work does not dare to adopt A.I. technology to make it sharp with a running cover stock for the first time in a long time, and it is super easy to handle. The heavyweight pin action is also an attractive ball.
