KBS TGI Shaft Review – Specs, Flex, Weight

In general, graphite iron shafts sacrifice accuracy for the sake of distance and control for higher handicap players.

But things are changing with golf gear technology all the time. KBS is known best for their steel iron shafts that are gamed by some of the best players in the world.

However, they are also doing a good job of innovating new technologies and not allowing themselves to be pigeon-holed. The KBS TGI is a graphite iron shaft that KBS says offers the performance of their tour spec’d steel shafts. We’ll be the judge of that. In the following review, we will be telling you about the strengths and weaknesses of this shaft as well as who should be gaming it.

KBS TGI Shaft Overview

In case you haven’t realized, TGI stands for Tour Graphite Irons – shoutouts to KBS for keeping nomenclature simple.

Of course, you can expect a lighter weight from these shafts when compared to KBS steel shafts. That was the whole point of the KBS TGI shafts.

They were designed to be more accessible than  their steel counterparts but to offer comparable performance. The fact that the KBS TGI is not available in extra stiff flex should tell you a little bit about the type of player this shaft was made for; but we’ll get into more detail about that a bit later.

This is truly a KBS shaft. Not only is the title simple; the design is simple as well. KBS likes to keep things straightforward and understated in terms of branding and we salute  them for that. The KBS TGI shaft has a matte black finish with a red block in the middle that contains all the lettering – much like their steel shafts.

One of the things we noticed pretty quickly was that the KBS TGI shaft has a stiffer tip than what we were used to with graphite shafts. In hindsight, we shouldn’t have been surprised. KBS shafts are renowned for their control and accuracy – the KBS TGI is no exception.

Why is the KBS TGI So Popular?

The KBS TGI gets “built-in” interest simply because it is a KBS shaft.

Over the past decade, KBS has really made a name for itself and has become a titan in the shaft market. On a subjective level, the KBS TGI is a popular choice for slower swing speed players and players with a more deliberate tempo because it gives the accuracy and control of steel KBS shafts.

How Does the KBS TGI Perform?

Yes, these are graphite shafts.

But you should withhold your preconceived notions about graphite shafts if you are considering getting fit for the KBS TGI. One thing we don’t like about graphite shafts is that the flex profile can be inconsistent throughout an iron set. That’s not the case with the KBS TGI shafts.

From the long irons to the wedges, the flex profile is consistent. The KBS TGI shafts don’t feel noodly but they flex enough to have a reactive feel. This is tempered by the stiff tip section though so you are still able to transfer all the energy from your swing into the ball. This is truly an amazing feat for a graphite shaft that doesn’t even come in extra stiff flex.

Another thing we were really impressed by was the tight shot dispersion. Yes, mis-hits will still veer off-line but as long as you are moderately accurate, you can expect straight flight with these shafts. When you load up on the KBS TGI shaft, you get an active response that never feels out of control. This shaft is stout enough to handle your heaviest swings while producing a mid-high launch and mid spin.

In fact, that was really the only gripe we had about the KBS TGI: the spin rates were a little high. But for some players, this is actually great news.

KBS TGI Shaft Specs

Available flexes Lite, amateur, regular, stiff
Weight 50, 60, 70, 80 grams
Butt .600
Tip .370
Length 41”

What Flexes Are Available? What Swing Speeds Do They Suit?

Sub 80 MPH swingers should try the lite and amateur flex options while 80+ MPH swingers should test the regular and stiff flexes.

What Weights Are Available? What Swing Speeds Do They Suit?

The 50 and 60 gram versions would work well for slow swingers with more deliberate tempos.

Chances are if you’re swinging your irons faster than 85 MPH, you’ll like the 70 or 80 gram versions.

Why is it So Good?

The KBS TGI is about as consistent as it gets for graphite shafts.

We loved the tight shot dispersion.

KBS TGI First Impressions

Our first few swings with the KBS TGI informed us that it was light and airy and produces mid-high launch.

Key Features & Performance

The KBS TGI features the E.I. curve that is used for KBS’s steel shafts.

This feature is partly responsible for the consistency and enhanced control you get from this shaft.

KBS TGI Iron Review

You get a bit of smash factor help from the flex of this shaft; but more importantly, the flexion stays the same throughout your set so you know exactly what to expect from each iron.

KBS TGI Wedges Review

The relatively high spin rate comes in handy in the wedges. If you play on a course that demands soft landings on the green, you will really appreciate the KBS TGI.

Who Should Buy it?

The KBS TGI shaft is an excellent choice if your swing speed is slowing down a bit and you want to transition to graphite iron shafts.

They will allot you the same accuracy and control as you steel shafts; but with the assist of higher flexion. This is also a great shaft if you like the precision of KBS steel shafts but need a lighter option.
