Which KBS iron shaft is best for you?

KBS iron shafts are for everyone from the world’s best golfers to slow-swinging amateurs, but which of their 14 models best suits you? Let us explain…

Golfers rarely give a second thought to which shafts are in a new set of irons. Yet, KBS believe 14 different models (all of which come in numerous weights and flexes) are needed to cover all types of players.

Technology has taught the brains behind KBS – Kim Braly, if he’s to fit hard-hitting tour pros alongside moderate speed, high handicap amateurs the brand needs a vast array of options. The thinking has led to the creation of 14 different steel and graphite KBS iron models.

EXPLAINED: How we test golf equipment

We don’t want to fit you for your perfect iron shaft. That should only ever be done with the help of a decent club fitter in the real world. But, to highlight how shaft technology helps you hit better iron shots more often we’ve taken a look at the full KBS line-up.

When buying your next set remember KBS shafts can change how a shaft feels, launches and spins, so you have the opportunity to choose your perfect ball flight and set-up. Here’s what you need to know about KBS iron shafts.

Players’ models  

KBS C-Taper iron shaft

There are three-pillar players’ shafts within the KBS line-up and each differs by balance point. The Tour is stiffest in the grip section (for good feel) and it gives mid-launch and mid-spin. The C-Taper is stiffest in the tip section (close to the head) to give a stout and strong feel and deliver low launch with low spin. The S-Taper fits neatly between the pair.

C stands for Constant Taper, so the shaft has no steps, which allows the C-Taper to have a strong and stout feel. Typically the model suits stronger golfers, and players can expect a 5% lower ball flight than True Temper’s Dynamic Gold. Major winners Gary Woodland and Justin Rose have played the C-Taper as has Rickie Fowler.

KBS $-Taper iron shaft

All three KBS pillar players’ iron shafts come in the same five weights, so golfers get to choose based on the launch, spin, and ball flight desired for their own game.

Half flexes (R+ and S+) are brilliant for golfers that sit on the fence between two flexes. They alleviate decisions around whether to go regular flex for more distance or stiff for increased accuracy. The S-Taper (Subtle Taper) is midway between the C-Taper (lowest spin and launch) and Tour shaft (mid-spin and launch).

KBS Tour iron shaft

The Tour is Kim Braly’s signature shaft, it was the first KBS model and it’s the mothership of KBS. Thanks to not being overly strong the Tour can suit a wide audience of golfers. Its consistent step pattern is a good fit for smoother, less aggressive transition players.

Thanks to being a high balance point model (so weight is positioned closer to the grip), golfers get a slightly softer feel and good feedback at the top of the swing. A further Tour FLT (Flighted) shaft model launches long irons higher and short irons lower for a more optimised set.

KBS Tour V iron shaft

KBS see the Tour V as an outlier shaft because the model is 10g lighter than the C-Taper, $-Taper, and Tour.

KBS Tour Rep Paul Steels says “the Tour V shaft is often a good fit for players who like the shot shape and flight of the C-Taper but want extra feel, as the C-Taper is just so boardy”.

KBS C-Taper Lite, $-Taper Lite, and Tour Lite iron shafts

There’s lots of misunderstanding around lighter iron shafts. But KBS say golfers should see their Lite models (which are 15g lighter than the standard models) as giving a little more launch and being easier to get airborne (than the 3 pillar models).

For players who don’t go at iron shots full tilt Lite models can be a really good option as club speeds increase and shots launch higher. Lite models and aging typically go hand-in-hand. If you happen to overload the shaft you’ll know because shots will start turning over left of the target (for a right-handed golfer).

Also, think about launch windows. A strong but very low launch player could see benefits by going Lite but in a strong flex to up launch and ball flight.

KBS Max and Max CT80 iron shafts

To ensure KBS have shafts to suit every golfer’s speed they produce ultralight Max and Max CT80 shafts as well. Both Max shafts are high-launch, high-spin models which help optimise ball flight for maximum carry distance at moderate speeds.

Remember it’s possible to be a fast but inconsistent high handicapper (in which case you’d be better suited to one of the KBS players’ shaft models), so think about shafts suiting speeds rather than ability. Thanks to their low kick point and high launch properties the Max shafts regularly make an appearance in stronger lofted irons (think TaylorMade Stealth and Callaway Big Bertha B21).

Typically high-speed players, irrespective of ability will not touch this product.

There are junior options too   

To ensure golfers can go through their whole golfing career with a familiar KBS feel, the brand also produce two junior steel shafts (the 560 and 580). Both are designed to suit the speed of 8 – 11-year-old players.

Both shafts are lightened steel, so the weights are similar to lightweight graphite iron ranges. But, crucially golfers don’t get a heavy head feel which can cause issues when switching from graphite to steel once a child is a stronger teenager.   

When should you go graphite?

Graphite irons shafts are massively misunderstood in the modern game. Many people think they’re for older golfers and slower speed players, which just isn’t the case. Graphite irons shafts are easier on the body. They remove vibration, and can suit everyone from tour players to very moderate speed club golfers.

In typical KBS fashion, the brand make three graphite models (all are available in numerous weights and flexes), here’s what you need to know about them.

How KBS graphite iron shafts differ in launch and spin

KBS TGI – Tour Graphite Iron shaft

KBS specifically target a steel-like feel from their graphite shafts. They’ve done such a good job fulfilling their brief several tour players swear it’s not actually graphite. Thinking instead it’s a steel shaft painted black.

The TGI can be matched to golfers’ speeds (there are eight weights, so the model can suit from 57mph to 100mph speed players) in exactly the same way as the brand’s steel shafts. The TGI is the company’s lowest launching and spinning graphite iron shaft, it’s pretty strong and stout, so decent players often like it.

KBS PGI – Players Graphite Iron shaft

In developing their shafts KBS have undertaken masses of research, and they say when the flex isn’t disclosed golfers often prefer the feel of graphite over steel. Their advice is to play the flex you need. Don’t be tempted to go stiffer than necessary. And if you swing a 6-iron at 70mph play a shaft that performs at that speed.

The PGI was developed to bring a steel-like feel to graphite and it’s a step up from the lower launching and spinning TGI. The PGI is widely played on the LPGA Tour, it’s the brand’s mid-launch/mid-spin graphite iron shaft. Six weights mean the model can suit from 57mph to 94mph players.

KBS Max graphite iron shaft   

The Max graphite is the highest launching and spinning graphite iron shaft in the KBS line-up. It’s a model for golfers who really need help launching shots high into the air to maximise carry distance. Five weights mean the model can suit swing speeds from 51 to 82mph.

Get it right the first time

KBS reckon so long as golfers get fitted correctly the first time they can progress through KBS models throughout their playing career. It means, if like Gary Woodland you’re a C-Taper player or Cameron Smith a Tour shaft player you stay within that family but progress to lighter models as you age.

And to demonstrate how important finding the right family is KBS say to look at Adam Scott and Gary Woodland. Scott has been a Tour shaft player for years (think of his smooth, under-control swing) whereas Woodland is a big strong hitter of the ball, so he’s a C-Taper guy all day long. But, switch their clubs over and both would struggle to play, as they wouldn’t get the ball flight or shot window they’d be expecting.    

Don’t forget your wedges

Today KBS are a through-the-bag shaft company. They make shafts for drivers, fairways, hybrids, irons, wedges, and putters, so if you’re taking the time to get fitted don’t neglect how the company produce five different wedges shafts too.

KBS say the Hi-Rev wedge shaft has been designed from the Tour shaft profile. There’s a lengthened tip section to give a softer feel and generate extra spin. If you play the Tour shaft you’ll likely enjoy this wedge model too. The brand’s 610 wedge shaft was designed to complement the Tour V shaft.

Where C-Taper and S-Taper fans often run shafts from their irons through into the wedges, albeit at a slightly lighter weight as wedge shots are rarely hit full out.

How do KBS iron shafts compare in data?

Verdict: KBS iron shafts

Lots of people will look at our test pro’s data and think the shafts are performing very much alike. But the data says nothing about how different the shafts felt.

Comparing the C-Taper and S-Taper the data shows the pair as being pretty evenly matched but the difference in feel was phenomenal. So different in fact our test pro felt he just wouldn’t be able to use the C-Taper effectively on the golf course (as it’s so strong). Where the $-Taper felt brilliant and could well be his perfect match within the KBS family.

The Lite shafts produced a faster ball speed, just as KBS promised and the C-Taper Lite in particular launched and flighted shots higher with a steeper descent angle, so there’s a huge amount of tuning in ball flight and feel available from shafts.

Just as KBS promised the TGI graphite shaft produced some very good optimal numbers too, they’d be a very sensible choice for golfers looking to avoid the shock and vibration of using steel shafts. Equally the Max graphite climbed to its peak height very early in its flight, which at lower speeds will be a real benefit in maximising carry distance.   

At the end of the day, KBS are all about the consumer. You get what you want, whether that be higher or lower launching, more or less spin, or a different feel, everything is on offer within the KBS iron family. Our test pro liked the $-Taper for his own game as it didn’t feel too strong, yet it felt stable and produced a good feel through the hands, and he had control over his ball flight.

KBS Founder Kim Braly on a life spend designing golf shafts

Many golfers won’t know the name Kim Braly, but the guy is a shaft legend. He has dedicated his life to creating the highest performance shafts you can buy, and we sat down with him. 

How have shafts evolved over the last 150 years?

A hundred of those years were dominated by hickory shafts. Steel shafts didn’t come about until the 1930s. My father patented “Frequency Matching” (in the 1980s) which has been the biggest breakthrough during my lifetime. Until then there were no standards; the method gave a baseline to compare and match shafts. Everything I’ve achieved since is down to the Frequency Matching method he invented.

How did the Frequency Matching idea come about?

We made titanium irons with tungsten weights and wanted to see how different set-ups affected performance. We organised a golf robot, and tried two identical set ups, yet the results were entirely different. We started questioning if shafts might not be matched. My dad developed Frequency Matching as a way to compare and match (for flex, weight, profile through CPM, cycles per minute) shafts to one another. The process hasn’t changed for 30 years.

You developed the Rifle and Project X shafts which are still popular; what was different about them?

No set of shafts had been designed individually for each club until then. They were a breakthrough. We’d follow the PGA Tour (at a time when there were no tour vans) and explain to players about matching their irons. We could match a whole set to the club they felt most comfortable and confident with. We were custom fitting without really knowing it.

I’m also proud of what we’ve achieved at KBS over the last 10-12 years. If we aren’t the leaders in shaft technology I really don’t know who is.

What was the players’ reaction?

They were super interested. We had lines of people wanting to understand how shafts affected performance. We learned all sorts. In relation to frequency the lightest shaft in the bag (the driver) will be the stiffest. The weakest shaft should be in the lob wedge, as there’s lots of shots hit less than full out, and a fraction weaker shaft allows you to know where the head is.

Today, the correct fit for players is often a flex and a half stiffer than we recommended 15 years ago. At the start we were a couple of guys just trying to understand. It wasn’t about marketing; we had our mathematical theory and we wanted to understand if it worked in practice.

How have launch monitors affected modern shaft fittings?

They’re one of the best things to have happened to golf. Launch monitors have helped people understand ball flight, spin, height and launch. Every shaft I’ve ever designed has been designed with a type of player in mind.

Each KBS shaft fits into a matrix, we’ve worked on them one at a time, and the line-up is nearly 100% complete.

Where do you start designing new shafts? Is it an idea from you, or a request from a player?

We have ideas, but they have to work in practice. In golf “feel” is a huge thing. If the feel is wrong products go nowhere. I’ve enjoyed dialling in the KBS Tour Lite (steel) and KBS PGI (Players’ Graphite Iron shaft) to be “everyman” golf shafts over the last two years.

They work at specific swing speed ranges, and thanks to our options we can optimise launch and spin for golfers swinging 6-iron in the region of 80mph.

You’ve worked on a bunch of top performing shafts, but which are you most proud of?

The Precision Rifle put me on the map, set up my career and I learned loads from it. The first KBS Tour shaft was a really big deal, too. It’s the foundation stone of every other KBS shaft, where all our other current shafts start. I’m awfully proud of it. 

Have you hit hickory shafts? How different are they to today’s models?

The last two tournaments I’ve played have been hickory challenges. Hickory weighs a ton (they’re 180g in a 6-iron), they’re really stiff but the torque is unreal. You can literally twist the head in your hand. Wood is strong in one direction – the one it’s grown in – which is up and down the shaft.

Will graphite shafts ever be the norm through the bag?

I’ve heard so many times how graphite represents the future. In terms of iron shafts steel is still a great material. The reason graphite became popular is its strength to weight ratio. It’s possible to make a 45in driver shaft at a “normal” swingweight.

You just can’t do that with steel, but you don’t need that as much in irons. Steel isn’t going away.    

KBS make 16 different iron shafts; why so many?   

Each of our profiles do different things. You may have the tendency to hit the ball low, so we have shafts designed to spin more and have a higher trajectory, and vice-versa.

For every 2.5mph of club speed change golfers need a different shaft flex, and that’s why we make half flexes. There’s also feel to consider. In our KBS Tour franchise we go from 130g to 90g in 5g increments (nine different weights), so golfers get what they need.

Whereas in a traditional three flex line-up (R, S, X) golfers get pushed into the best option available. KBS have a reputation for making good feeling shafts because golfers get shafts with the correct load at impact, which naturally feels good. Everything really does come back to fitting.
