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. RADICAL ENGINEERING. By increasing the distance between the front and back weights, we are 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. RADIAL WEIGHTING EXTREME 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. RAD TECHNOLOGY 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 us even more discretionary weight to position more mass forward within the frame to decrease spin and increase ball speed. RADSPEED DRIVER HANDICAP RANGE: 0-15 The RADSPEED Driver features a traditional (460cc) shape and forward-biased RADIAL WEIGHTING in addition to front to back movable weight technology to deliver the fastest ball speeds, lowest spin, and the most workability of the three models. RADSPEED XB DRIVER HANDICAP RANGE: 5-15 The RADSPEED XB (XTREME Back) Driver features an oversized (460cc) shape and back-biased RADIAL WEIGHTING to deliver the longest and most forgiving ball flight with low spin. RADSPEED XD DRIVER HANDICAP RANGE: 5-25 The RADSPEED XD (XTREME Draw) Driver features an oversized (460c) shape and heel-biased internal RADIAL WEIGHTING to deliver the fastest and straightest ball flight with maximum slice-fighting power.
