Stiff Flex. The RAD SPEED XB Driver features an oversized head shape and back-biased Radial Weighting for the longest and most forgiving ball flight with low spin. The back-biased Radial Weighting system positions 20g of weight in the back of the head for more forgiving performance. The new Carbon Wrap Crown system is 30% thinner to create extra weight that can be repositioned to optimize swing performance. A refined T-Bar Speed Chassis is lighter and allows for even more redistributed weight towards the front in order to decrease spin and increase ball speed.
