The flex of your golf shaft is an important factor that shouldn’t be overlooked when it comes to your game, as it can directly influence the launch angle, spin rate and distance of a shot.
As much as finding the right flex can seriously optimise your performance, using the incorrect shaft can lead to inconsistency and frustration.
So, we’ve provided a very brief and simple explanation of what the shaft flex in your clubs means, and how to go about choosing the right one for your game.
Understanding shaft flex
Shaft flex refers to the degree to which a shaft bends during your swing, and is largely linked to your swing speed — although, there are several other factors to consider (as you’ll see below). But, before that, it’s good to know what the most common shaft flexes are:
Regular: For golfers with moderate swing speeds.
Stiff: For golfers with faster swing speeds.
Extra Stiff: For golfers with very fast and often powerful swings.
Factors affecting shaft flex selection
As mentioned above, several factors can influence the ideal shaft flex for a golfer:
Swing speed: This will influence which shaft you need more than anything else. A fast swing speed will usually require a stiffer shaft to control the launch angle and prevent excessive spin. If you are unsure of your swing speed, you can use this handy calculator to work out a rough estimate.
Clubhead speed: This is the speed at which the clubhead strikes the ball. A higher clubhead speed will often necessitate a stiffer shaft to prevent excessive lag on the downswing which can cause off-centre strikes.
Shaft weight: A heavier shaft can help to provide more control and stability. This can be suited to golfers with slower swing speeds, allowing the “club to do the work” so to speak.
Torque: Torque can be a confusing word when associated with golf, especially when it’s usually used as a motoring term. However, the torque in a shaft measures its resistance to twisting. Lower torque shafts provide more control, while higher torque shafts can promote higher launch angles and forgiveness.
What the numbers say
While specific data can vary, here’s a general breakdown of shaft flex recommendations based on swing speed and clubhead speed:
Note: These are general guidelines, and individual preferences and playing styles may influence the optimal shaft flex. It’s always recommended to get a professional club fitting to determine the best shaft flex for your specific needs.
Additional considerations
Age and physical condition: As you age, your swing speed and strength are likely to deteriorate. To compensate, softer shafts can utilised for reduced power in the swing.
Playing style: Aggressive golfers looking for distance will be better suited to stiffer shafts, whereas those looking to maintain an easy-going rhythm — Freddie Couples & Ernie Els for example — may see the benefits of a regular or softer shaft.
Equipment preferences: The type of driver, fairway wood or iron can also play a part in shaft recommendations. As all engineering is designed for different types of golfers, the shafts best suited to them can vary. Some clubs will be built for a higher launch angle — such as game-improvement irons — while Tour Preferred irons will likely be better matched with stiffer shafts.
So, what shaft flex do I need in my golf clubs?
By knowing the factors that influence shaft flex and considering your individual needs, you can take the first step in understanding what might work best for your game. However, as always, it’s best to see a fitting specialist before making any big financial decisions.
