Created with human intelligence yet perfected by the artificial kind, MainFrame is a one-of-a-kind face design that has a milled pattern on the backside of each ZX Iron face to increase ball speed on every shot. While our engineers set the parameters, our computers ran the simulations—thousands of them—until we had our fastest irons yet.
The key to better iron play is consistency. To improve spin and distance consistency, the ZX5's grooves are progressive. The 3i-7i feature wider grooves, ideal for longer shots in all conditions. While the 8i-PW have deeper, closer set grooves, perfect for cutting through grass and debris on approach. The result is consistency across the set: both long and short irons delivering repeatable, reliable performance, with fewer surprises.
Tungsten in the toe of ZX5's long and mid irons (3i-7i) increases MOI for more stability and forgiveness. That added stability is invaluable on off-center shots because it helps keep spin and speed consistent. A forged SUP10 face enhances speed and distance while a forged 1020 Carbon Steel body absorbs vibrations for an extremely soft feel
Tour V.T. Sole
The unique Tour V.T. Sole gives Srixon irons a leg up against the competition with smoother turf interaction and improved impact feel. The V-shaped sole glides smoothly through turf, even if you
strike slightly behind the ball. ZX5 Irons also feature the resurgence of our popular sole notches. Revered by our tour staff, these heel and toe notches enhance workability without sacrificing forgiveness.
