The flex of a golf shaft is the amount that the shaft bends in response to the force applied by the golfer during his swing. Every golfer has a different level of force that he applies to the club which will determine how much flex he needs. The more force you apply, the stiffer a shaft you should have and vice versa.
I use steel shafts in my irons and graphite shafts in my woods. I prefer steel because they just feel better to me and I like the way they sound when I hit them and they give me more feedback during my swing. Graphite is good for people who want a lighter weight club (graphite is lighter than steel) which reduces fatigue over an 18-hole round. Some people also say that graphite absorbs some of the vibration from impact better than steel so it feels softer on their hands, but personally, I don’t believe this is true at all.
Now let’s talk about flexes in golf shafts: we have three basic categories: regular, stiff and extra stiff (or “X”). And then within those three categories there are further gradations like: R300, S300, X100 etc… But for now, let’s stick with our three basic categories: regular, stiff
Golf shafts are the second most important component to your golf clubs. The shafts are what helps transfer energy from your body, through the club and into the ball. Each golfer is different and there are a variety of things that affect the flex of a golfer’s swing such as weight, height and strength.
What is flex? Flex is how much a golf shaft bends during your swing. It is rated on a scale of 1-10 with 1 being the stiffest and 10 being the softest. Choosing the correct flex for your game will improve your accuracy, distance and feel for the ball.
There are two major components that affect how much flex you need in a shaft: club head speed (how fast you swing) and tempo (how quickly you swing).

Q: I am a 16 handicap and I think my shafts are too stiff. How can I tell if they need to be replaced?
A: Check the flex of your shaft with a frequency analyzer. Modern analyzers can check the shaft frequency in as little as 3 seconds and can also show you what the effect of swing weight adjustments will have on the entire balance of your club.
Shaft flex is a critical element in designing a club that fits your game. In general, steel shafts will play softer than graphite shafts. The stiffness or flex of a shaft will determine how quickly a shaft releases or “unloads” its stored energy during the downswing. Shaft flex is not just determined by the golfer’s strength; it is also dependent upon the tempo and transition of their swing, as well as their release point.
If you have been playing golf for any length of time, chances are that you have heard the term “flex” being used. The flex of a golf shaft refers to the amount of bend or bow that occurs during a swing. For example, if you were to grab a golf club at the grip end and put your other hand at the club head, then push and pull on the club, you would notice that it bends. This is the shaft flexing.
The flex of an individual golf club can be determined by looking at the shaft itself. On most steel shafted clubs it will be written directly on the shaft, usually close to where the hosel meets with the shaft. Graphite shafts often have a flex code printed somewhere on them as well – usually in small letters near where the grip is attached to the shaft.
The reason for differing levels of flex in different clubs is due to how much weight and speed is transferred through the club during a swing. Different clubs require more or less force behind them in order to achieve optimal distance and accuracy.
The shaft of a golf club has one purpose; to transfer energy from the golfer’s body through the club head to the golf ball. The flex of the shaft is designed to help this energy transfer occur and can be selected based on swing speed, tempo and body size.
There are four basic shaft flexes; extra stiff, stiff, regular and senior. Extra stiff flex is for golfers with a swing speed over 105 mph who are looking for a low-launching penetrating ball flight. Stiff flex is for players between 95 and 105 mph who desire mid-high launch conditions with optimum spin rates. Regular flex is for players 85 to 95 mph who want a high launching ball flight with maximum spin. Senior flex is for players below 85 mph who need to help get the ball in the air as much as possible.
A 5 iron will have different shaft flexes depending on the club manufacturer because all manufacturers have different specs depending on their target market. For example a 5 iron may have a regular shaft in one set of clubs but may have a stiff shaft in another set of clubs. The best way to determine your ideal shaft flex is by getting fitted at your local professional shop and having them recommend the proper shaft based on your swing speed, tempo and body size.*
It’s well known that golfers tend to fall into one of two categories:
Those who think they need more distance, and those who think they need more accuracy.
There are many factors which will affect the distance of your shots. However, one of the most important factors is the design of your golf shafts.
What Is A Golf Shaft?
The golf shaft is the long cylindrical part of your club which connects the grip to the club head. It’s a vital part of your club, but one that’s often overlooked by many amateur players.
When you swing a golf club, the shaft bends slightly during your backswing, then returns to its original position before being hit by the club head.
This bending movement helps transfer energy from your body to the ball during impact, increasing distance and accuracy. However, it can also cause problems if you use a golf shaft that doesn’t match your swing speed or style.
For example, a player with a slow swing speed may struggle to get enough speed from their club to return their shaft back to its original state. This would cause a loss of power and poor shot accuracy for that player.
The shaft is the engine of the golf club. It is responsible for delivering the energy that you create in your swing to the ball. Proper shaft selection can allow you to maximize your distance and accuracy. You need to know what you are looking for before you can make an informed decision about golf shafts.
First, consider the length of the shaft. The general rule of thumb is:
The taller you are, the longer your golf club should be. Men’s standard golf clubs are between 43 and 45 inches long. Women’s standard golf clubs are between 41 and 43 inches long.
The length of a golf club can have a dramatic impact on your game if it is not correctly adjusted to suit your height and swing style. If a club is too short, it will be difficult to hit shots as the bottom of your swing arc hits the ground too early. If a club is too long, it will be hard to control your shots as you cannot get a firm enough grip on the club for accurate shots.
