Overview/Technology-

The UST AXIVCore is a carbon-fiber weave shaft that maximizes hoop strength with an end result of an absolutely superior energy transfer when compared to its peers.  But UST didn’t stop at providing an ultimate energy transfer machine, it created a shaft with built in counter balancing to make a medium weight shaft feel lighter.  The bottom line is a lighter “feeling” shaft with an energy transfer that promotes faster club head speed, higher launch, and lower spin and we know what that combination means for for us mortals – added distance.

So what exactly sets AXIV technology apart?

“AXIV Technology is a proprietary 4-axis material that UST is using in the design of its latest and most technologically advanced shafts. What is AXIV Technology and how does it work? Through our partnership with Japan’s Mamiya OP, we have developed this unique woven graphite fabric that combines graphite fiber in four distinct directions that maximizes torque, flex and hoop stiffness in one single layer of material compared to standard two- or three-directional woven materials.”
