Adams Golf started the aerodynamic revolution in golf several years ago with the original Speedline driver. The innovative shaping and refinement of the clubhead gave golfers a driver they could swing faster for more distance. This new technology platform gained numerous accolades and vaulted praise from aerodynamicists, engineering labs, and golfers of all abilities and swing speeds.v Three years later, the new Speedline F11 driver has even better aerodynamic qualities than previous models and more forgiveness than any aerodynamic driver that's come along. The new patent-pending Velocity Slot Technology that's visible on the crown and sole keeps the airflow attached throughout the swing which reduces the amount of drag while increasing the speed of the swing. A higher swing speed translates into a higher ball speed which then results in more distance.
