The RADSPEED XD Driver features an oversized head shape and heel-biased internal Radial Weighting for the fastest and straightest ball flight with maximum slice-reducing capability. The heel-biased Radial Weighting system places a 10g weight in the heel, making it easier to close the face for straighter, more draw biased drives. 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. An infinity edge CNC Milled face expands the milled area by 95%, increasing the zone of maximum ball speed.
