The NEW! King F9 Women's Speedback driver is the first Cobra Driver to successfully combine an aerodynamic club shape, a low center of gravity, and a precision CNC milled face.WHAT IS ITSPEEDBACK Technology is a revolutionary advancement in engineering, creating the first driver to successfully combine an aerodynamic shape with a low center of gravity to optimize club speed and ball speed for maximum distance. WHO IT'S FOR Three different models (9.0, 10.5 and 12.0) feature 8 adjustable lofts and a front to back adjustable CG system, allowing golfers of all abilities (Tour to 25 handicaps) to find the perfect launch & spin configuration for their game.WHY WE MADE ITOur engineers identified a common problem in today's driver designs: to get optimal aerodynamic properties, you have to sacrifice other parts of the design. SPEEDBACK™ Technology is a revolutionary breakthrough in driver engineering and is the first to combine a streamlined, aerodynamic shape with a low center of gravity. Paired with the only CNC milled driver face, it delivers substantial improvements in club speed, ball speed and distance without sacrificing forgivenessTHE ULTIMATE FORMULA FOR SPEEDLonger starts with Faster. Faster starts with SPEEDBACK, a revolutionary advancement in low CG, efficient aerodynamics, and precision CNC milled face technology that delivers the Ultimate Formula For Speed.CNC PRECISION MILLED FACEIn an industry where everyone claims to have a fast driver face, ours is the only one that is CNC milled. A process that is up to 5 times more precise than conventional hand-polished driver faces, CNC milling delivers our thinnest and hottest face design repeatedly on every driver.SPEED TUNED PERFORMANCEDual Roll adds distance to your drives by reducing the gear effect that negatively impacts launch and spin on shots hit high and low on the face. Each driver is SPEED TUNED with optimized top and bottom curvatures to tune launch and spin for different swing speeds and attack angles.COBRA'S FIRST EVER CARBON WRAP CROWNContinually pushing the boundaries of innovation, Cobra engineers have created our largest carbon fiber crown design that is the first to wrap over the crown onto the body. This design produces a 12% larger carbon fiber area that saves 10 grams compared to titanium driver crowns.TUNE YOUR BALL FLIGHTThe KING F9 SPEEDBACK drivers feature adjustable center of gravity (CG) and MyFly loft technologies, allowing you to fine-tune trajectory and launch to maximize distance.
