Graphite iron shafts are now a serious part of the premium fitting market, and KBS has built a range that covers very different types of golfer. Some models are designed to feel as close to steel as possible. Others are aimed at easier launch, lighter total build and greater playability for moderate or developing swing speeds.
That matters because moving into graphite is no longer a single-lane decision. A golfer can choose graphite for comfort, speed, launch, feel or simply because they want a better overall build. KBS TGI, PGI, MAX and GENERATION all speak to different versions of that need.
Talk to Outtabounds about reshafting, replacement shafts and practical build advice for irons, wedges, hybrids and woods.

Why golfers move into graphite iron shafts
The most obvious reason is weight. A lighter shaft can help many golfers maintain speed, launch and strike quality, especially as the set gets longer. But weight reduction is only part of the story. Graphite can also change how the club feels on repeated practice sessions, which is a real consideration for players who hit a lot of balls indoors or on mats.
Some golfers move to graphite because they want less vibration. Others simply want a more efficient build that creates height and carry without feeling loose. The KBS range is strong here because it offers both player-style graphite models and more game-improvement oriented options.
| Model | General design idea | Best known for | Typical golfer fit |
|---|---|---|---|
| TGI | Steel-like graphite iron | Control and weight-specific fitting | Player wanting graphite without giving up iron-like feel |
| PGI | Players graphite with wide weight spread | Playability and control in graphite | Broad range from improving golfers to stronger players |
| MAX Graphite Iron | High-launch graphite based on swing speed | Easy launch and lighter build | Moderate swing speeds seeking height and distance help |
| GENERATION Graphite Iron | Lightweight high-launch graphite | Junior and developing player support | Younger golfers or very light-loading players |
TGI: the steel-like option
TGI is the KBS graphite iron shaft that most directly speaks to golfers who want graphite to behave like a serious iron shaft rather than a soft alternative. KBS describes it as built for maximum steel-like playability, shot control and performance, with the same E.I. curve as the KBS Tour steel profile. That makes it a natural test for players who like the idea of graphite but do not want the club to feel disconnected.
This model is often attractive for players who have lived happily in steel for years and want to reduce vibration or fine tune weight without losing the flight discipline they trust. It can be particularly compelling if you are building a mixed practice routine that includes plenty of indoor balls and want graphite benefits without a dramatic change in response.

PGI: broad playability without giving up control
PGI sits slightly more broadly in the market. KBS describes it as a steel-like performance graphite shaft built for anyone, with weights ranging from 50 grams to 100 grams. The emphasis is on tight tolerances, dispersion and control, but within a package that opens the door to many more swing profiles.
In fitting terms, PGI is often a very practical answer for golfers who want the club to feel lighter and easier than a traditional steel build but still want the flight to look like an iron shot rather than a purely launch-assisted hybrid-style delivery. It is one of the easiest models in the KBS graphite family to recommend as a first test.
MAX Graphite Iron: easier launch for moderate speeds
MAX Graphite Iron is built from the same family idea as the steel MAX products and is aimed at players using swing speed rather than traditional flex labels as the best guide. KBS says it is designed to help lower swing speeds launch the ball higher with more spin and accuracy in a lighter package. That makes it very relevant for golfers who simply need help getting the iron up in the air consistently.
This is not a niche product for beginners only. Plenty of club golfers with decent technique still benefit from a lighter, higher-launch graphite iron if it improves carry gaps and makes the long end of the set easier to use. If your mid and long irons feel like work, MAX Graphite Iron is one of the KBS options that deserves a proper test.

GENERATION: a clear route for younger players
GENERATION Graphite Iron is designed specifically around younger players and lower swing speeds. KBS links it to the MAX family logic, but for the next generation of golfers who need high launch, added spin and very manageable overall weight. For junior development, that is a meaningful category rather than a minor side note.
A lot of families make the mistake of leaving younger golfers in ill-fitting hand-me-down shafts for too long. A shaft like GENERATION can help a young player build a cleaner swing pattern because the club is no longer asking them to force launch or speed that the build itself should be providing.
| If this sounds like you | Best KBS graphite starting point |
|---|---|
| You want graphite but still prefer a steel-style response | TGI |
| You want broad graphite playability with real control | PGI |
| You need easier launch and lighter total weight | MAX Graphite Iron |
| You are fitting a junior or very light-loading player | GENERATION |
How to choose between them
The cleanest decision comes from looking at the problem you are trying to solve. If you like your current iron flight but want less vibration or a better weight fit, start with TGI or PGI. If you need the ball to launch higher and carry further with less effort, MAX is more relevant. If the player is still growing and developing speed, GENERATION is designed for that job rather than pretending junior golfers should fit into adult categories.
Graphite fitting becomes much easier when you compare it in a repeatable environment. Indoor testing can be especially useful here because carry, peak height and spin patterns are easier to compare from session to session. If you are researching how equipment fits into a home practice setup, see our pages on building a golf simulator in the UK and golf simulator garden rooms.
And if the next step is a rebuild rather than a brand new iron set, our club reshafting service helps turn those test results into a finished club that actually reflects the chosen shaft properly.
