Launch where needed
The progressive tip helps long and mid irons climb for players who need more peak height.
More height in the long irons, classic Steelfiber in the scoring clubs
Aerotech Steelfiber · Golf ShaftsSteelfiber FC (Flight Control) keeps the Steelfiber construction but adds a softer, progressive tip to launch the mid and long irons higher. The shorter irons keep the stable feel Steelfiber is known for. This parallel-tip version fits .370" iron heads and is trimmed at the tip and butt, in 70g, 80g and 90g.

Why golfers choose it
The progressive tip helps long and mid irons climb for players who need more peak height.
Short irons retain the steady, controlled Steelfiber feel.
70g, 80g and 90g weights suit players looking for easier speed than steel.
