The Adams Idea Pro Black CB2 irons are forged cavity back irons that are more forgiving than the CB1's. Forged of the same soft carbon steel this set is for players that want the same quality construction and premium look with added features to make them more playable. The cavity of the CB2's features dual perimeter weighting to lower the Center of Gravity to increase launch angles and increases Moment of Inertia for added forgiveness. The CB2's also feature a progressive offset throughout the set that makes the longer irons easier to hit while preserving the control and workability of the short irons.
