Bring precision, feel, and stability to your iron game with Aerotech SteelFiber Iron Shafts. Featuring patented SteelFiber technology, these shafts blend a high-modulus graphite core wrapped in micro-thin steel fiber—providing a unique combination of strength, lightweight responsiveness, and excellent ball-striking control.
