About this item XL HEAD DESIGN This is huge: a bigger head means an MOI of 3,081 g-cm2in the 7-Iron—ourmost ever in a Cleveland Golf game-improvement Iron. It’s maximum distance with maximum fun. MAINFRAME Designed using artificial intelligence, MainFrame variable face technology increases ball speed while unique weight pad designs ensure maximum forgiveness across the face. ACTION MASS CB An 8g weight placed inside the end of the grip delivers better balance for more control without extra effort. V-SHAPED SOLE An elevated leading edge glides through turf with far less drag than a typical flat sole to maintain speed and power on heavy strikes.
