While distance is always the number one goal & desire with golfer's, it comes in different forms. The Radspeed XB (Xtreme Back) is for golfers who need plenty of speed & distance but also value forgiveness highly & crave a club that flies effortlessly straight & true hit after hit. The Radspeed Xtreme Back Driver features an oversize head profile that will inspire confidence while standing over the ball. The aesthetically pleasing 460cc head utilises rear-biased radial weighting to produce much faster & straighter ball flight out of all the three Radspeed models.
