The falacies of Golf Shaft flex

I am sure that you have gone to buy new golf clubs and you got confused with the shafts. One golf club you tried in a R flex felt similar to the one in the S flex, how can that be? That’s because there are no Golf Industry “Flex Standards”. One companies A flex is another companies S flex! That’s not right, no it isn’t and unfortunately the only ones that suffer is you the golf fanatic. Fortunately we level the playing field, through using the same system the top shaft companies use to define there shafts flex.

Ever go to one of the big box stores and see the high end fitting sets for clubs with shafts labeled 5.0, 5.5, 6.0 etc? That is the universal reference system for flex in the industry. Unfortunately, not all companies use this standard, due to the inadequacies in there golf shaft designs. The better companies try to follow these guidelines to promote the quality and consistency of there golf shaft designs, others ignore it and rate there shafts by what they can acheive with there shafts, and rate them according to how they relate in flex to other shafts in there collection.

Typically you will see fitting sets with higher end shafts with denotations of flex at 5.0, 6.0 or 7.0 etc., using an industry standard for GOlf Shaft Flex. These fitting sets are only seen used by the most demanding and precise high end shaft and club companies. To help provide more precise fitting to top golfers seeking expensive high end golf clubs. Unfortunately they don’t offer heads in your ability to try with these systems, don’t worry you aren’t missing much. Why because these sets are terribly inaccurate the way they are developed, simply because the weight of the golf heads vary and the listed shafts are “Profiled” to feel like a 5.0 or 6.0, they arent actually that flex every time.

That’s all we use, the original FM Precision Frequency matching scale, later referred to as the Project X scale. Simply because the founder and designer of Project X Shafts was Kim Braly and they popularized it for tour players. Kim Braly was the co-founder of this engineering based frequency oscillation flex scale along with his father in the mid 70’s. Your probably wondering why, if it was developed in the mid 70’s why did it take so long to be implemented? It’s hard to get OEM companies to change to something that can ultimately be there down-fall to another brand, easy answer.

Why do we use this system exclusively? To provide you the top performance in fitting you for custom golf clubs, and provide you with exact tolerences for your custom golf clubs. something the big box stores cant provide to you, they don’t have the resources. Really, you find that hard to believe, go to the big box store, get fitted with one of there fitting sets, and try to buy that exact golf club, you cant. They order a “similar” club for you, that’s based on components that are similar to the one you hit, not the one you hit.

We are different, we guarantee you will have no difference in performance and the club we build you will feel identical to the one you hit in our custom golf club fitting set. We back that up, with performance testing. When we deliver your clubs, we have you warm up, then hit the fitting club you tested, then present you with your new identically matched custom golf clubs to compare them. We guarantee they are identical in feel and performance or we will fix them for you, no charge until you are satisfied.

Our system combines the best of both worlds! We have combined the principles and engineering practices of Frequency Matching golf clubs, which is used by every Equipment manufacturer during research and development of their clubs especially in shaft design. We then put that technology into your set of custom built golf clubs. Why don’t the OEM’s use it in sets they sell? Simply because they would have to charge $15000 for a set of custom irons instead of $1400.

OEM’s simply aren’t set up for true custom golf club work, they are set up for mass production. I know you are assuming that when you order custom clubs from a big box store and they are coming from an OEM, they spent a lot of time putting them together! Right? You couldn’t be any further from correct, they have someone working for minimum wage or a sweat shop in another country banging those sets together in about 45 minutes combined time for a set of irons. Not 8-10 hours as the process we use does to make a custom set of golf clubs.

You think to yourself, well when I was fit at the Big Box store in Paramus, they had designations on the shafts like 5.0, 5.5 so when I get my clubs they will be a true 5.0 like I ordered right! Uuuuuuuh nope, couldn’t be further than correct. We just worked on two sets of clubs that were ordered from OEM performance centers, one was a set of Mizuno MP69 Tournament Blades, the other a set of Taylormade Speedblades. Both are quality heads, played on Tour by PGA pro’s, so you are getting the same quality the Pro’s get going to there performance center right!

Wrong, you are getting mass produced golf clubs with literally next to no true quality control, in terms of matching or Precision. Although the Mizuno set cost our client over $2400 originally, he was absolutely unable to play them with any consistency. There were two problems, one he didn’t belong playing those heads they were entirely too advanced of a head for him, yet they fit him for them anyway: the other problem, the flex, although he was fit by a Mizuno performance studio and determined to be a 6.0 flex and ordered a 6.0 flex. What he got was not a 6.0 flex. He received a set of irons that varied in flex from 6.4 to 7.7 flex ratings! So everything he hit he had to put everything he had into the shot and he had no consistency, they were way too stiff. When we fit him, he was a 5.4 flex, doubt what we say, take a look at our blog, this would be Jeff M from New Jersey, he pretty much says it all.

During our fitting we analyze your specific swing taking into account every characteristic that affects your swing and generate club speed. We take every aspect of it into consideration, how you load and unload our wrists, your transition points, swing tempo, angle of attack, weight transition, everything that makes your swing unique and then math it to the proper type of shaft and the exact flex profile that gives you the best performance possible. into consideration the shaft bend profiles of each shaft we have to determine the proper shaft selection for a customer, we can apply the principles of frequency matching to give our customers a perfectly matched set of clubs. That’s right we use this system to reverse engineer your specific swing, to give you the most technically advanced combination of shafts and heads that will give you the best advantage for performance in your game.

With the technology we have in our shop, backed up by the design and development of our fitting sets, we can determine your exact shaft loading profile. Using our frequency oscillation equipment we can then duplicate from the fitting club you hit an exact replica of that club and in the case of Irons we can then build an entire set to match the precise feel and performance of the fitting club. Sounds like a profound statement, has you thinking, imagine having 14 go to clubs? Reaching into you bag and having the confidence that every club is your go to club. No more second guessing a shot, no more thinking well that’s my 6 iron I really have to put everything I have into it to hit it right, or that’s my 9 iron I have to hold back my swing to make it fly right.

We level the playing field with our Dynamic Frequency Fitting system and our build process which is exclusively frequency matching. We engineer every golf club to your precise and unique swing characteristics, giving you the advantage of a perfectly matched set of clubs. Ever wonder how the Pro’s on TV can swing so effortlessly and make the ball perform as they do? They are fit to there full shaft loading profile, everything they can handle effortlessly and nothing more. Meantime you are swinging as hard as you can and struggle to get the performance you see them have. Exhausted or running out of gas to finish the round by the 14th hole? That’s because there clubs are properly fit for them by qualified Professional’s. They don’t go to the big box stores for there clubs, they go to custom fitters, that specialize in performance just as we do.

Dynamic Frequency Fitting

Is our answer to a proper fitting for clubs. We have spent years developing a system that essentially allows a customer to find the correct shaft and head combination for there individual needs. We have taken our years of experience with Golf Fitting and applied use. Combined that with comments from customers about what makes them comfortable with knowing they have the correct equipment. Taken the systems that equipment manufacturers use in there research and development and created a complete version of the OEM’s vastly abridged and inaccurate version of fitting sets to a practical application that can be described as the ultimate fitting set on steroids!

This has become our mission over the past 10 plus years to develop a system that is seemingly bullet proof and leaves nothing to a customers imagination, except the vision of being truly able to improve there game.

What sets our fitting system apart, the way it is built and designed. Using precise engineering specifications from each shaft we have in our set we developed a system that uses the exact shaft flex profile for each shaft in a dynamic and uniform system to walk a customer through the selection of the correct head and shaft combination for there game.

Our set not only has flex ratings for each shaft, it has flex ratings for each shaft type in 3 CPM increments, by shaft type and weight. With the ability to fit a customer for the specific torque and flex profile that performs best for them. We actually find your exact shaft loading profile for your swing. What works best for you, not just close, exact shaft loading profile. Through the development of our fitting set we can take you through all types of shafts, by shaft weight, torque and bend profile.

Whats a CPM, that would be the “Cycles Per Minute” or the frequency the shaft oscillates at which determines its actual stiffness. Translation, the actual true stiffness of the shaft with force applied which affects the shafts unique dynamic performance. The same test criteria that every shaft manufacturer uses to determine the stiffness of the shafts they make.

By using this system we have set up our fitting set using our heaviest MB fitting head we are able to keep all shafts at a relative flex regardless if we are fitting you with lighter heads than the master head. How does that work? Lets use our master head as an example, it is 263 grams, when we attach it onto a fitting shaft using our Faz-fit fitting system we can record the actual frequency of that shaft, with that head. For an example we will say that it oscillated at 300 CPM at 37 ½” in length. We record that on the shaft, the next shaft in the set from the same type of shaft and same Raw (uncut) length would be targeted to have a frequency of 303 CPM. SO we take the raw shaft and cut it to length to achieve that finished rating of 303 CPM.

We have done this throughout our entire fitting set, categorizing each shaft type and logging the actual frequency of the raw uncut shaft from the factory. Thus when we order a shaft, we can call and say we need 10 shafts for a set of irons, the original frequency of the fitting shaft was 274 CPM and the shaft companies we deal with will send us 10 shafts that are 274 CPM, one may be 275 or 273, but we have the target frequencies we need to produce a set of clubs that will dynamicly match the one we fit you for. Obviously there is a lot more to it than that, but we have the basis to build a set of clubs for you that will provide as close to a perfect match in flex profile as is possible. We will have to then match the flex slope for the individual but we have scientifically analyzed each shaft for its unique properties and have the capability to provide you with a true matching set of clubs using the FM Precision shaft flex profile that the top manufacturers use to produce there shafts.

What do we have that is so unique?

We have the ability to let you try the exact head and shaft combination we intend to build for you and build your set to match exactly to the one we build you. We put heads individually on fitting shafts, that have listed frequencies or “Stiffness” that we have recorded through using our frequency analyzer to record that specific shaft. Then after we fit you, we can take that exact combination you hit and approved and duplicate it for you, using engineering principles just as OEM manufacturers use in there design and development. However, that is where it stops with

Our approach to fitting is based upon years of research not done by us, but the golf industry themselves. Fathered from the research of Kim Braly , founder of KBS Shafts & his father DR. Joe Braly a professional engineer, developed in the 70’s. Using there method, that is still used in all golf shaft Research and development performed TODAY in 2015 we can provide our customers a much more precise analysis of there swing and choose the correct shaft loading profile for them.

Yes that’s correct all golf shaft industry research and development companies use the same system to design to develop dynamic shaft bend profile charactristics determining the shafts loading characteristics including flex potential and flex charactersitics as we use in our fitting system to determine our customers full shaft loading profile.

Ever hear shaft designers refer to the shafts Ei? Ei refers to a shafts bend profile and defines dynamic behavior of the shaft or how the shaft reacts to the loading force during the downward transitional force that is applied to it in your swing. The amount of energy applied to the entire shaft through each golfers individual ability to apply the force to the shaft during the downward transition of his swing and the way the force is applied to the shaft and loading at the transition point.

Each golfer has a unique swing which includes wrist cock motion and release combined with unique acceleration points creating individual and unique swing characteristics, this applies the force and creates the torque to propel the ball at the Moment of Impact.

Thus demonstrating how that shaft reacts individually to the applied force and transfers that energy with direct force at the moment of impact to the golf ball. In engineering terms the actual Torque generated during the swing is the force that propels the Golf ball. Please understand that this explanation of torque is not what is referenced in a shafts specifications listing of torque, that is the actual rotational torque of that particular shaft under stress applied by the weight of the actual club head.

How does this affect my clubs and why do you need to know the shafts characteristics to determine what shaft I need? The big box store told me all they need to know is my swing speed and the launch monitor tells them the rest.
Johnny, they couldn’t be further from correct. Fitting based on swing speed alone is a recipe for disaster. That’s the difference between true custom fitting and buying a big box disaster story of your own!
