This is the Adam ACSS shaft.
ACSS stands for Adam Center-core Super Shaft.
The ACSS shaft is very light and enormously stiff because it uses special space-age materials to line the core of the shaft; which creates less deflection and enhances feel.
This shaft has a hole, bored in a certain pattern, from the bottom of the shaft all the way to the top, after which space-age secret components are injected to line the inside of the shaft creating exceptional control.
This shaft features Adam's patented X2 double jointed system, which produces a much firmer hit; perfect for 3-cushion billiards.
This shaft creates more side spin than any other shaft available!
