Aerotech SteelFiber i80 Graphite Iron Shaft Review

You’ve seen them played on tour and you’ve read about them in magazines, but are they good enough to try in my irons? I’m talking about the Aerotech SteelFiber graphite iron shafts. If you are like me and like reading all those golf forums, you run into someone asking about these shafts, with all sorts of positive replies from the members.

I don’t have a fast swing, in any respects, but I never thought I was in the range of graphite shafts in my irons. There is a stigma of players who use graphite in their irons and by no means am I anywhere old enough to get a senior discount for my early bird special dinner.  I went to a local fitter friend of mine and he fit me into a set of Aerotech SteelFiber i80 shafts.

These shafts are the best of both worlds – Graphite core with a steel jacket. Aerotech covers the graphite shaft with over 59 miles of steel fiber, and each fiber is only 8 microns, or 1/10th diameter of a human hair. What does that mean? Longer AND straighter shots in all your irons. I was first skeptical at this statement, but after I got them in my irons – I was a believer.

At first glance, the shaft doesn’t stand out. A good shade of gray with the logo in the middle of the shaft, and they seem to match with almost any head out there. Really low key, but they did use nice paint and a good clear coat, so it still has the feel of a quality product.

After getting a set installed into my irons and out on the range, the first impression I had was the feel. I’ve hit graphite shafts before, but this is the firmest graphite iron shaft I’ve ever hit. The shaft felt like it stayed there after impact and because it was graphite, the vibration dampening and the overall feel was buttery and fantastic.

After a dozen shots, I noticed that my shot dispersion got smaller. Yes, smaller. From going from R300 to an 80 gram graphite shaft, I expected a light INCREASE in my shot dispersion, not less. My club fitter did tell me to expect this, and at first I was skeptical, but after seeing how my irons played, I became a believer.

Another feature about the SteelFiber shafts I really liked was the ballfight. I didn’t notice much difference from my R300 steel to the SteelFiber shaft. With the same launch angle as steel and being 50 grams lighter, I gained almost a club length in distance with the SteelFiber shaft. Normally with graphite iron shafts, there is always one errand shot that is 10-15 yards longer than the rest. So far with 4 rounds and 3 driving range sessions, I have not experienced this with the Aerotech shafts.

The only down side is cost – these are $40 each and they are not the most expensive iron shafts out there, but for this price I expected something to look better. If you care more about results than looks, you will be in love with the steelfiber shafts, since it was designed and engineered to lower your strokes, not turn heads.
