The RADSPEED XB (XTREME Back) Driver features a slightly oversized profile at address (460cc) and 20 grams of back-biased RADIAL WEIGHTING to deliver low spin, and the fastest ball speed with maximum forgiveness. By increasing the distance between the front and back weights, Cobra is able to create faster ball speed while maintaining forgiveness. A perfect balance of front and back RADIAL WEIGHTING delivers low spin for enhanced speed with maximum stability. The RADSPEED XB driver features 20g positioned in the back (14g of fixed weight and a 6g interchangeable weight) to create maximum stability for forgiveness on off-center hits. An additional 8g of fixed weight is positioned in the front to lower spin for faster ball speeds and the longest drives. An infinity edge face design expands the milled area by 95%, increasing the zone of maximum ball speed. A lighter carbon wrap crown design features a new carbon fiber material that is 30% thinner which creates another 6 grams of discretionary weight that can be repositioned to optimize performance. A refined T-Bar Speed Chassis design is 7 grams lighter, giving us even more discretionary weight to position more mass forward within the frame to decrease spin and increase ball speed. If you would like to customize the shafts, grips, lengths or lies give us a call or send an email to Tom@dallasgolf.com. Standard Cobra warranty applies and satisfaction is guaranteed.
