RADIAL WEIGHTING FOR RADICAL DISTANCE.The RADSPEED XB (XTREME BACK) Driver features a slightly oversized profile at address (460cc) and 20 grams of back-biased RADICAL WEIGHTING to deliver low spin, and the fastest ball speed with maximum forgiveness. RADICAL ENGINEERING - 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 RADICAL WEIGHTING delivers low spin for enhanced speed with maximum stability. EXTREMEM BACK WEIGHTING - 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. FRONT WEIGHTING - An additional 8g of fixed weight is positioned in the front to lower spin for faster ball speeds and the longest drives. CNC MILLED INFINITY FACE - An infinity edge face design expands the milled area by 95%, increasing the zone of maximum ball speed. THIN-PLY CARBON WRAP CROWN - 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. T-BAR SPEED CHASSIS - A refined T-Bar Speed Chassis design is 7 grams lighter, giving Cobra even more discretionary weight to position more mass forward within the frame to decrease spin and increase ball speed.
