The Under Armour Undeniable Composite Shaft is a great shaft that takes offset to a whole new level. The axis offset increases feel and control by lowering the ball even further below the midpoint of the handle. The Undeniable Composite shaft is created out of UA's unique blend of composite material for the toughest impacts. The unidirectional inner layer combined with the 12K weave on the outer layer makes this shaft virtually indestructible. In addition, the Undeniable shaft comes with an adjustable endcap so you can decide where to set the shaft for better whip and feel. This new technology makes for advancing your game even further than you thought.
