The inception of the Dual-Drive was born of a sprawling development process that has spanned years. This could not be achieved without placing a weight block of specific size and shape inside of another weight block. The outer weight block incorporates strategically placed geometric shapes that, in conjunction with the inner weight block, establishes a new standard in bowling ball motion – faster revving action with a higher level of energy transfer at the pins.
