KBS TGI Vs SteelFiber Shaft Comparison Overview
Graphite iron shafts are hit and miss – in my experience, mostly miss.
It’s really hard to strike that perfect balance between speed/forgiveness and control/stability.
So I was really intrigued when I read about the SteelFiber shaft. It is a graphite shaft with, you guessed it, steel fibers infused into it.
When I got the SteelFiber shaft in for testing, I wanted to compare it to one of the best graphite iron shafts I’ve ever swung: the KBS TGI shaft.
Read on to see how the SteelFiber fared.
KBS TGI Shaft Overview
“The TGI shaft runs the gamut from a 60g version to a 110g version. There are also regular, regular+, stiff, stiff+, stiff++, extra stiff and extra stiff+ options.”
I stuck with my preferred extra stiff (100g) flex for this test. The KBS TGI has a stiff tip section which goes a long way towards giving this lightweight shaft more control.
The bend point is in the middle but you have to swing surprisingly hard to notice it.
Again, this is one of the best graphite iron shafts I’ve ever tested because of how stable it is.
At a much lighter weight point, you can get close to the control of steel with this shaft. The transition is exceptionally smooth and the club head stays true to your swing path.
SteelFiber Shaft Overview
“The SteelFiber is available in weights from 74g to 125g. Stiff, extra stiff, regular, ladies and senior flexes are also available.”
I tested the SteelFiber in stiff flex at 110 grams. The first thing I noticed was the incredibly low torque.
Right away, I was reminded of a steel shaft. But the responsiveness was definitely indicative of a graphite shaft.
I loved the low spin rates and tight dispersion this shaft yielded.
I did find it a bit more difficult to correct face angles compared to the TGI shaft; but it didn’t have much effect on accuracy. Even on heavy loads this shaft seemed to resist ovalling very well.
“I would say the feel/stability combination of the KBS TGI shaft still reigns supreme; but the SteelFiber certainly gives it a run for its money.
Both of these shafts are excellent for anyone who needs a lighter shaft that offers the control of steel shafts.”
