UST Proforce Axivcore Tour Black Wood Shaft:

For the player seeking high initial launch, low spin, and increased ball speed.

PROFORCE AXIVCORE Tour Black wood shafts are tour-proven designs that integrate a true weave — 4-axis material — within the inner walls of the butt section that provides stability and consistent shaft recovery. This counter-balanced shaft series reduces club heft, helping players gain more MPH of clubhead speed.  They also feature superior high modulus carbon fiber in the mid and tip section. The Tour Black Series’ flexible, low torque tip section offers high launch, low spin, and better control, and is available in multiple weights and flexes to fit various swing profiles.
