MainFrame is a variable thickness pattern of grooves, channels, and cavities carefully milled into the backside of ZX4 Mk II, ZX5 Mk II, and ZX Mk II Utility Iron faces that maximizes flex at impact. MainFrame not only boosts COR, it also repositions mass away from the face and into the toe and sole for a lower Center of Gravity. This creates more than just faster ball speed, but also more consistency and forgiveness, enhancing all aspects of your Iron play, shot for shot.
Sole notches on the heel and toe sides lessen drag by reducing the amount of surface area that contacts the ground. Ultimately, they provide better clubhead speed through turf and improve shot versatility without sacrificing forgiveness.
FORGED MULTI-PIECE CONSTRUCTION
ZX Mk II Utility’s forged SUP10 faces are strong yet light—increasing face-flex at impact for enhanced speed and distance—while a forged 1020 Carbon Steel body absorbs vibrations for a softer feel.
UST MAMIYA RECOIL DART 90
UST Mamiya’s Recoil Dart shafts now come standard as a graphite offering for ZX5 Mk II, ZX4 Mk II, and ZX Mk II Utility Irons. The new DART technology (Dual Action Recoil Technology) helps provide greater overall consistency, an optimal feel at impact, increased ball velocity, and precise ball flight for all golfers.
