Ball Motion

A lower Rg allows this power pearl to start digging in earlier than the original Adrenaline™, while the pearl cover makes sure that there is still a motherload of energy to plow through the pins on medium, or heavier, lane conditions.

Posi-Traxx™ Pearl Reactive
Posi-Traxx™ Pearl Reactive

This evolution of our most versatile coverstock starts to deliver a smooth, powerful transition soon after clearing the heads, then continually builds without ever becoming a typical skid-flip type pearl.

GC-90XL™
GC-90XL™

The power of the original GC-90™ core has been kicked up a notch by increasing the body density, then enlarging the ball wrap. This change effectively lowered the Rg by moving more mass to the center without sacrificing any other core dynamics.
