What is the true frequency of a golf shaft?
To find any shaft’s true frequency, the shaft is placed in a clamp with the clubhead dry fit on the end of the shaft. Then the club maker pulls the shaft to make it oscillate. This oscillation is measured in cycles per minute (cpm’s). The faster the shaft oscillates the stiffer the shaft is said to be.
Can two different shafts have the same Butt frequency?
And equally, it is quite common for two shafts to have the same exact butt frequency measurement but be completely different in their stiffness design over the rest of the shaft. Here’s a couple of examples to illustrate this point.
What is the butt diameter of a golf shaft?
The butt diameter is measured about 2" down from the top of the shaft. For standard size shafts for adult players, this will usually be around 0.600", (or larger if it's a bubble shaft). The butt diameter is important to note because you'll want to match that measurement as closely as possible with the core size of the golf grip.
What is the right frequency for your golf swing?
The right frequency for your swing depends on the speed and acceleration of your swing as well as WHEN you release the club (when you stop accelerating). When we discuss frequency, we start out with the shaft frequency.
What does butt frequency mean?
Refers to the resonant frequency of a shaft when the butt (handle) end is anchored and the tip is made to vibrate. Usually, the shaft is anchored at the butt end when performing a resonant frequency test.
What is the butt of the shaft?
BUTT: The top end of the shaft, called the butt, is located underneath the grip. Shafts have different amounts of torque and flex in the butt, just as they do in other sections of the shaft.
What is frequency in shaft?
The frequency of a shaft is the number of cycles per minute a shaft will oscillate when one end is fixed (clamped) and the other end is pulled down with a weight attached to it. Ideally a flex (such as Stiff, Regular, or X-Stiff), should correspond to one frequency number.
What does frequency matching golf shafts mean?
Frequency matching shafts only measures the butt flex of the shaft and allows the club maker to perfectly match a set of golf clubs. It is up to the club fitter to match a shaft to the golfers swing needs. Golf shaft manufacturing processes, while having improved by leaps and bounds, are still imperfect.
How do I measure my butt for a golf shaft?
If you're not sure what the hosel ID is, you can measure it with a fine tip gauge or contact the club manufacturer for this information. On the opposite side of the shaft is the butt end. This is the side where the golf grip will be installed. The butt diameter is measured about 2" down from the top of the shaft.

Or making a closed shoulder is the effect that it has on swing weight.
How is shaft frequency measured?
Simply put, CPM stands for “cycles per minute,” which measures the frequency of a golf shaft. To obtain this measurement, a fitter or club builder places the grip end of a golf club into a clamp, then pulls on the tip section of the shaft and releases it to make it oscillate.
How do you determine the flex of a golf shaft?
Start by using a launch monitor to analyze your golf swing speed. If your swing ranges between 85 mph and 95 mph then you should start with a regular flex. If your swing speed is faster than 95 mph, then you should try a stiff shaft.

How do you find the frequency match?
In the frequency matching approach, we have to proceed differently....Matching in a case control study in practiceFor each case...Select a potential control from the pool of controls available.Repeat step #2 until three successes occur.Repeat step #1 until all cases have been matched.
How do you measure a stiff shaft?
There are numerous ways to measure shaft flex. The most common way is to clamp the butt end of the shaft, attach a weight to the tip, displace it, and measure the CPM (cycles per minute) or frequency that the shaft oscillates. This can also be done in reverse – clamp the tip and weight and displace the butt.
What is individual matching?
Individual matching is a method of controlling a priori a confounding factor when setting up groups to compare.
Who first discussed shaft oscillation frequency?
The concept of using shaft oscillation frequency was discussed in the 1968 book, “Search for the Perfect Swing” by Alastair Cochran and John Stobbs. “Search for the Perfect Swing” is one of the first explorations of golf technology.
Is shaft frequency used to measure stiffness?
Shaft frequency is not of much use in evaluating shaft stiffness. The problem for club makers and fitters who recognized the importance of shaft profiling was that there was not an affordable EI instrument until I designed and manufactured one. They used the frequency instruments they had.
Do golf shaft stiffness rates work across brands?
The systems we have to rate golf shaft stiffness do not work across brands or even across models within brands. Most experienced club fitters use their experience to understand golf shaft stiffness. Many use some systematic method, most often frequency, to rate the shafts they work with.
What is a CPM in golf?
An electronic device called a frequency analyzer counts that oscillation rate and displays it as cycles per minute (CPM). "In a set of woods or irons, the frequency reading of the shafts in the clubs will normally increase from longest to shortest club in the set.
Is flex rating important in golf?
For most golfers, not very: it trails well behind shaft weight, flex rating and bend profile in importance for all golfers. It does matter at the margins, however, and so, relatively speaking, is more important to the best golfers than it is to most golfers.
Does frequency matching help golfers?
But, Wishon said, frequency matching trails multiple other shaft factors in importance: "If the shaft weight, shaft flex and bend profile are not fit properly to the golfer, frequency matching will not help the golfer. It is far more important to properly fit the weight, flex and bend profile to the golfer than to worry about frequency matching in ...
What is a taper tipped shaft?
Taper tipped shafts, which are used by all of the big manufacturers, are designed to be mass produced and dropped into a particular club’s head and the cut to length i .e. a 9 iron shaft for a 9 iron head. These are difficult if not impossible to match perfectly.
Do two different types of shafts measure at the same frequency?
This, however, does not mean that two different types of shafts which measure at the same frequency will play the same. Shafts have different bend profiles – which means they are stiffer or softer in different areas of the shaft.
Is golf shaft manufacturing imperfect?
Golf shaft manufacturing processes, while having improved by leaps and bounds, are still imperfect. This means that if you go to the local golf retail store and buy a set of “off the rack” clubs and later get the shafts measured for frequency, you will find that the vast majority of those sets will not match.
What is the shaft of a golf club?
Many consider the golf shaft the "engine of the club". Golf shafts are either made from graphite or steel. Both types have its benefits and disadvantages. Either way, the golf shaft is where power is stored and released at impact. Sitting in between the golf grip and club head, a solid connection is what allows the golf shaft to do its job.
What is shaft flex?
Shaft flex is a description of how much a shaft will bend under the force of a golf swing with a head attached at the tip end. The speed and frequency of your swing will determine what flex you need. There are generally 5 different flex notations (from most bendable to least bendable): A-flex (Senior), L-flex (Ladies), R-flex (Regular), ...
How long is a 0.370" iron shaft?
decreasing in length from #3-PW). 0.370" parallel iron shafts arrive in uncut lengths, usually 41" or 42" for irons or 46" or more for woods.
What happens if you swing too heavy?
If the overall club is too heavy, you can lose swing speed which can result in a loss of yardage. Too light of a club will be hard to guide and control which can lead to mishits. Players with faster swing speeds or more accelerated tempos can benefit from heavier shafts.

A bit of confusion because I have never really cared about shaft frequency but I do now....
Blade
It says raw shaft but it doesn't say what weight they put on it. I have a frequency meter which came with two different tip weights. I can't remember how much each weighs. All that stuff is still in my garage in NM. But, the amount of weight you put on the end, or if you tip the shaft will change the cpm dramatically.

Frequency is often confused with relative shaft flex but essentially they are two different things.

ok so it's only an estimation of the butt frequency. OK so what do you think about this:

That's the thing. There is no real standard. Each mfg has their own. You can probably find some charts to give you a general idea though.
