Ball Motion
Think of the GC-90™ core as the big block engine that’s designed to hook up with the early traction of the Posi-Traxx™ Solid coverstock, then deliver a strong, continuous power band through the back end for punishing pin carry.
Posi-Traxx™ Solid Reactive
Our most versatile coverstock delivers early traction without over reading the front part of the lane. Scuff it. Polish it. Whatever you want. It will always come through when it’s crunch time.
GC-90™
This big block has been tuned to deliver a rush of energy that starts early in the mid-lane, and continues through the pins. Features include a shaved side for a slight MB, and an undersized wrap for a higher C.O.R. than what’s typical of a 3 piece ball.
