KBS Tour 90 shafts

[ltom]

I recently ordered Cobra King SZ irons from Dicks.  I ordered regular shafts. 

The shaft label says KBS Tour 90 S.  Does anyone know if this means they are stiff shafts?

If so, are these good for someone with 92MPH driver swing?

The S on the shaft does indicate that they are stiff. Without seeing your swing tempo and transition hard to tell if they would be ok. Based just on swing speed they may be a little stiff for you.

The S is for stiff.  Way back in the day of golfwrx, there was a thread in the clubmaking forum started by Howard Jones that used software to show the relative stiffness of shafts.  He could put several shafts on the graph at one time and show how stiff they were in comparison to each other.  His software showed the KBS Tour plays quite soft to flex, almost a full flex softer than some other brands.  All of that to say, you shouldn't have any problems with these.  In fact, it's what I've got in my Mizuno 900 Forged right now (and I've played them in a few others before) and my driver swing speed is also in the 92-94 range.

I really like the clubs , but they do feel a bit stiff.

I think this is the thread I am thinking about: 

 

Unfortunately, it's such an old thread that many of the attachments have been lost over the years after software changeovers or just being deleted.

Ok good to know, thanks so much.

I have KBS Tour 90 R-flex in my irons. My driver CHS is just below 90 MPH.

 

I got the CB Pro Tungstens right when they were going out of production. The shop had two sets of new CBs, one in Tour 90 R-flex and one in S-flex. I did a side-by-side with both flexes over two days, and decided to go with R-flex. Just went through the ball smoother, and was slightly longer. (And, I was 67 years old...)

 

Like my CBs, your King SZ irons have a parallel tip hosel (0.370" diameter). Parallel tip KBS Tour 90 shafts (uncut) weigh 101 grams in R-flex and 102 grams in S-flex. So only real difference is S is slightly firmer, not heavier.

 

Old FCM chart showed original KBS Tour as having a "middle earth" flex compared to other irons. KBS Tour 90 should be easier to handle.

Yep - Stiff.  Depends on your swing mechanics & tempo.  Those Tour 90 shafts are 95g-100g+ depending on tip; more of a mid-bend and active tips creating a higher trajectory.

Should I go by feel?  If so they seem very stiff and i'm tiring out towards end of a round.  I'm in decent shape, maybe I need to hit the weights to get stronger.

How old are you if you dont mind me asking? My brother has them in his hmb irons and they are very very light ane very responsive lively feeling. I just so happen to really like them and i only swing my driver maybe 100mph. They are very accurate as well. They can be hit high or low also. Underrated for a lightweight steel shaft to be honest. I swing them fast and slow and still get the same great responses. Im 32 my brother is 25. These should be light for you and feel great.

You may grow into them as your game progresses. I agree that they are a bit soft to flex. I demoed a set and compared them to a set of Dynamic gold R 300s I have lying around and they felt very similar from a stiffness perspective. Just a bit lighter. My driver SS is in the low 100s but I have a smoother tempo and they were a good fit for me.

I concur. Hit the Tour 90 stiff in 6 iron and 9 iron Ben Hogan PTX Pro irons and I was impressed. The stiff is a 102 gram shaft, the regular is 90. High quality shaft. I would say the OP either has the speed or can build the speed to play them.
 

That’s not too heavy. And you are not too old! If you are getting tired swinging a 102 gram shaft I would offer two suggestions: Give it time to adjust and make sure you are not swinging too hard and gripping the club too hard because that causes fatigue and zaps speed. The entire key to the game is to get the club swinging fast, don’t try to swing it hard. Only costs you speed. 
 

Here is an informative review on how stable they are versus much heavier models.

I have KBS Tour 90 R-flex in 2 sets of irons and really enjoy them.  I also have a driver head speed of 92.  I do not find them to play soft.  I've not tried them is S flex, so can't offer a comparison.  As others have mentioned, they are a high quality, lightweight steel shaft.

[Strategery]

KBS Tour 90 R are excellent shafts for moderate swing speeds.

I demoed the PTX Pros in the KBS 90 R. Really liked the feel of them. I ended up buying a set of PTX Pros in graphite and I def don’t like them as much as the steel shaft. Great shaft.

I’m with ya brother. I am trying hard to like graphites — no doubt the quality is better than ever — but it still seems like the balance and ‘heft’ of steel in irons is good for calming my tempo from getting quick.

Yeah I’m kicking myself for not buying steel. My dispersion is terrible with graphite. I bought the graphite because I got a great deal.

FWIW,

I moved to KBS Tour R flex several years ago.

You did get a Stiff set, or they were mislabeled, as my stickers have the small R.

Oddly, when I had a second set redone with the Tours - fitter left the stickers off.

Glad I know what was installed.

Ok... yeah im more then sure it they should be ok for you to swing. My dads in his 50s and he can swing them and connect well and he is no fast swinger as well. They are about as light as it gets as far as steel options. That being said.. everybody is different and going what feels best and natural to you is really whats best.

I ended up selling the stiff shaft clubs on craigslist and bought cobra reg shaft clubs from some one on golfwrx. The reg shafts are working way better for me.

Received these shafts in a recent iron set I bought, but I was expecting/wanted the KBS Tour 110. They are the parallel tip so not a significant difference in weight <10g from the 110. My 52* has the KBS Tour Wedge shaft and my 46* has the KBS Tour 110, so I'm curious to see how I play with the Tour 90 R in irons. Generally, I have a moderate tempo with a 90 - 100 driver SS and probably around mids 70s for my 7-iron. It's my 145 - 150 club and I'm fine with R flex. What I'm curious is if this gets me a ball flight I like. The lofts on the irons were weakened a bit so that will already help with trajectory and I'll be interested to see how the shafts fit to that. I feel like my swing gets a mid to low flight which I prefer to keep. If these help my accuracy and hold a few more greens then of course that will be satisfying. Only had one chance with them so far on the range yesterday so time will tell. Based on everything I've read these should be a good fit so we'll call it a happy accident until otherwise.

i've had my irons shafted in these around 4 years ago, and they've been snapping at the hosel for every one of them.
