World Alliance™

World Alliance™

Design

At Roto Grip, we rule the lanes! You need the best equipment available if you want to do the same. So as we designed the new World Alliance we looked at the key factors like coverstock, surface preparation, and mass properties of the weight block and created a combination which we are sure will be appreciated across the globe!

Some balls in the Royal line are built on a mild asymmetrical platform like the C.A.M. ™ core design to balance transition and entry angle. The new World Alliance will step on the gas pedal a bit with the more dynamic, proven Pinnacle™ core to help increase entry angle.

When polished to a smooth 1500-grit, the resilient Armor™ coverstock clears the heads with ease, reducing the coefficient of friction values. Since this means that the ball loses speed slower, you’re sure to see a more powerful impact at the pins. And the hybrid version found here gives the later breakpoint without being oversensitive to drier portions of the oil pattern. Put it all together and you’re ready to take on the world!
