AeroTech STEELFIBER FC90 Iron Shafts - Graphite - .370 Tip

AeroTech STEELFIBER FC90 Iron Shafts

The AeroTech STEELFIBER FC90 Iron Shafts are designed for golfers who want refined launch control throughout their set — with elevated trajectory in the long irons and traditional SteelFiber flight in the scoring clubs. Built around SteelFiber’s signature composite construction, the FC90 adds Flight Control (FC) technology for targeted performance where it matters most.

Featuring variable tip stiffness, the FC90 profile promotes a higher ball flight in the mid and long irons to help generate added carry distance and steeper descent angles into greens. Meanwhile, the scoring irons retain the trusted low-launch characteristics that have made SteelFiber a top choice among elite players. This strategic profile shift ensures better gapping and total shot control across the full set.

Weighing in at 90 grams, the AeroTech STEELFIBER FC90 Iron Shafts provide an ideal balance for moderate-tempo players seeking a smooth transition from graphite’s vibration dampening to the dependable feedback of a steel-like shaft. From long-iron carry to short-iron accuracy, this model is a complete solution for players who value versatility and consistency.

If you’re looking for an iron shaft that adjusts to your game throughout the bag, the AeroTech STEELFIBER FC90 Iron Shafts offer performance-tuned feel, responsive flight control, and the signature stability that defines SteelFiber technology.
