The RadSpeed XB Tour Length driver achieves our highest MOI ever at 5700 and is configured with a shorter 44.5” playing length, and a 14g weight to deliver optimal distance and accuracy off the tee. As the name states, the RadSpeed XB is designed for eXB speed, distance and forgiveness. A larger shape features a 17 gram tungsten back weight to achieve a higher MOI. A revolutionary advancement, the Cobra KING RadSpeed Driver is the Ultimate Formula for Speed. Cobra’s most forgiving driver utilizes a larger shape with more perimeter weighting and a tungsten back weight to help accomplish the highest level of MOI. A CNC Milled Infinity Face helps to ensure the face is machined to precise specs for optimal performance. Cobra’s 360 Carbon Wrap Crown wraps around the body to save 25g of weight for enhanced stability.
