You have lost 15 metres with the driver over the past ten years.
What should you change?
Your driver? Your shaft? Your swing? Your physical training?
The answer often sounds remarkably simple in golf equipment discussions. As golfers age, speed declines. Therefore clubs should become lighter, loft should increase and shafts should progressively move from stiff to regular and eventually to “senior”.
It is an appealing logic because it turns ageing into a predictable sequence of equipment changes.
It also has one major weakness: it starts with the solution before identifying the problem.
In the first article in this series, we used almost 10 million drives recorded by Arccos to establish that distance genuinely declines with age. Among male golfers with handicaps below 5, average driving distance falls from 263 yards between 20 and 29 to 239 yards between 50 and 59, 227 between 60 and 69 and 209 between 70 and 79.
In our examination of swing speed and ageing, we also saw why this happens. Strength changes with age, but so does the ability to produce force quickly. Crucially, those physical qualities remain trainable.
So we know the phenomenon.
We understand part of its mechanism.
What we still need is a diagnosis.
Because a golfer who has lost 20 metres has not necessarily lost those 20 metres for one reason.
Before looking at distance, look at speed
Imagine a golfer who carried his driver 220 metres at 50 and now carries it 200 metres at 65.
The first question should not be:
“Which driver should I buy?”
It should be: Has my clubhead speed actually declined?
Clubhead speed tells us something about the energy the golfer is bringing into the system.
If it has fallen from, say, 95 mph to 85 mph, an important part of the problem has already been identified. The engine is producing less speed than it once did.
The cause still needs to be established. Physiological ageing, reduced strength and power, lower activity levels, injury, changes in swing mechanics or a combination of several factors may all contribute.
Measuring the decline does not yet explain it.
But at least we know it exists.
Now imagine the same golfer still produces 94 mph but has nevertheless lost 20 metres.
Blaming age or physical condition immediately becomes much less convincing.
The next place to look is what happens between the clubhead and the ball.
What are you doing with the speed you still have?
This is where ball speed becomes important.
Two golfers can move their drivers at exactly the same speed and generate different ball speeds. The relationship between the two is commonly expressed through smash factor.
In simple terms: ball speed ÷ clubhead speed = smash factor.
A golfer swinging at 90 mph and generating 135 mph of ball speed produces a smash factor of 1.50.
At the same 90 mph but only 126 mph of ball speed, the figure falls to 1.40.
The engine has not changed.
The efficiency has.
Smash factor is not, by itself, a complete diagnosis of swing quality. But comparing club and ball speed immediately helps separate two problems golfers routinely confuse:
having less speed available and transmitting the speed you still have less effectively to the ball.
This becomes particularly interesting as golfers age.
One player may have lost several mph while retaining excellent strike quality.
Another may have preserved much of his physical speed but gradually lost consistency of strike or changed his impact conditions.
Both walk off the course saying exactly the same thing:
“I’m getting shorter.”
They do not necessarily have the same problem.
How is the ball using that speed?
Even excellent ball speed does not guarantee optimal distance.
Once the ball leaves the face, launch angle and spin become critical. The optimum balance between launch and spin also changes according to the golfer’s club and ball speed.
That last point is fundamental.
There is no single ideal launch angle or universal spin number that every golfer should chase regardless of age or speed.
And that means equipment that worked perfectly at 52 may no longer extract the same performance from the same golfer at 67.
Not because the club has become too old.
Because the golfer for whom it was fitted has changed.
Case 1: you really have lost speed
This is the most straightforward situation.
Your driver speed has fallen significantly. Strike quality remains good and your launch conditions show no major problem.
The main issue is therefore likely to exist upstream from the ball.
Changing equipment might allow you to use your remaining speed more efficiently, but no driver can physically recreate mph your body is no longer producing.
This is where physical preparation becomes relevant.
Strength, power, the ability to generate force rapidly and golf-specific speed remain at least partly trainable, including among older golfers.
That does not mean every golfer should embark on the same programme. Health, training history, injury and current physical condition matter enormously.
It simply means that buying another driver may amount to optimising the consequences without first addressing the cause.
Case 2: the club speed is still there, but the ball speed isn’t
Now consider a second golfer.
Clubhead speed has changed very little, but ball speed has fallen much more substantially.
The question becomes one of strike and efficiency.
Where are you contacting the ball on the face?
Has the vertical or horizontal pattern of your strikes changed?
Has your movement changed?
Does the club still allow you to find the centre of the face consistently?
In this situation, trying to develop more physical speed may be secondary.
You already possess part of the potential you are looking for.
You simply no longer convert it into ball speed as efficiently.
Technical work may therefore offer more value than speed training. Equipment may also contribute if club length, overall weight, balance or other characteristics are making consistent contact more difficult.
The question is no longer: “How can I swing faster?”
It becomes: “Why isn’t the ball benefiting from the speed I already have?”
Case 3: speed and strike are fine, but the trajectory is costing you yards
There is a third possibility.
Club speed is appropriate.
Ball speed is appropriate.
But the trajectory is not using that energy efficiently.
A ball launched too low, too high or with unsuitable spin for the available speed can sacrifice carry.
The cause might involve technique, dynamic loft, angle of attack, impact location or the interaction between golfer and equipment.
This is where fitting becomes particularly interesting.
Not because the golfer needs a hypothetical “senior driver”, but because we need to determine whether the current driver still produces appropriate launch conditions for the current golfer.
That distinction changes the entire fitting conversation.
The first question should not be: “How old are you?”
It should be: “What does your swing produce today, and can we use it more efficiently?”
Case 4: everything has declined
This is probably the least attractive scenario, but it may be one of the most common after several years without objective measurement.
Clubhead speed has fallen.
Strike quality has deteriorated.
Ball speed has declined even further.
Launch conditions are no longer appropriate.
In that situation, looking for the cause of the distance loss makes little sense.
There are several.
Imagine a golfer who loses some physical capacity, unconsciously changes his movement to accommodate reduced mobility and continues using a driver originally fitted ten years earlier for a different speed and ball flight.
His body, technique and equipment have all evolved.
They simply have not necessarily evolved together.
The solution may therefore need to address several areas as well.
This is exactly why measurement is more useful than intuition.
The “senior shaft” problem
This may be the most obvious commercial shortcut in the entire discussion.
You are 67.
Therefore you need a senior shaft.
But what exactly is a senior shaft?
Flex designations are not governed by one universal standard across the golf industry. A Regular in one shaft family does not automatically reproduce the behaviour of a Regular in another. Weight, bend profile, torque and the way a golfer loads the shaft all matter.
More importantly, age is not a mechanical characteristic of a golf swing.
Two 68-year-old golfers can have completely different speeds.
But even two golfers with similar speeds can possess very different tempos, transitions, physical strength, delivery patterns and preferences for feel.
The word “senior” describes their demographic category.
It does not necessarily describe the shaft they need.
A lighter club is not automatically a faster club
The same problem applies to weight.
It seems intuitive that making a club lighter should allow an ageing golfer to swing it faster.
For some players, it may.
But it is not a law.
Weight also affects control, rhythm, feel and potentially the way the golfer delivers the head into impact.
A lighter club that produces slightly more clubhead speed while significantly degrading strike quality may leave the golfer worse off.
Once again, measurement settles a debate that theory cannot.
Test it.
Measure it.
Compare it.
If a lighter configuration produces more clubhead speed and more ball speed while maintaining acceptable dispersion, it has achieved something useful.
If club speed rises but ball speed falls and dispersion deteriorates, the attractive number in the “club speed” column does not necessarily represent better golf.
The objective is not to win a clubhead-speed contest.
The objective is to play better.
More loft can help — but not because you turned 65
Exactly the same principle applies to loft.
As speed declines, changing loft may help produce more useful launch conditions.
But age is still not the determining variable.
Two golfers swinging at 85 mph may deliver the club with very different angles of attack and dynamic lofts.
Automatically giving them the same loft simply because their speeds are similar would already be an oversimplification.
Giving them the same loft because they happen to be the same age would be even less defensible.
Golfers should keep a record of their own ageing
There is one piece of information very few golfers possess, yet it could become extraordinarily valuable:
their own performance history.
We know our old handicaps.
We vaguely remember how far we used to hit particular clubs.
Some golfers keep scorecards for decades.
But how many know their actual driver speed at 45?
Their ball speed?
Average carry?
Spin?
Strike pattern?
Dispersion?
And then the same measurements at 50, 55, 60 or 65?
The spread of radar and launch-monitor technology has changed what is possible. For the first time, an amateur golfer can realistically build an objective record of how his game changes over time.
That history would tell him far more than a table showing how far the average golfer of his age hits the ball.
Population data tell us what tends to happen to golfers.
Your own measurements can tell you what is happening to you.
Five numbers before changing anything
For a golfer who notices a significant loss of distance, a small group of measurements can therefore produce much better questions.
Clubhead speed, to determine whether the engine has slowed.
Ball speed, to measure what actually leaves the face.
Strike quality and location, to understand the efficiency of energy transfer.
Launch angle and spin, to examine how that ball speed is being converted into flight.
Carry and dispersion, because actual golf performance remains the final judge.
Those numbers will not automatically provide the solution.
Their first purpose is more important:
they stop you solving the wrong problem.
Ageing is not a fitting specification
After 50, 60 or 70, changing equipment may be entirely appropriate.
Changing certain aspects of the swing may also be appropriate.
Working on strength and power may be appropriate.
Doing all three may be the correct answer.
But none of those decisions should follow automatically from the date on your birth certificate.
The first article in this series showed that age changes golf performance statistically, while golfers of the same generation can still be separated by dozens of yards.
Our examination of swing speed showed that some of the physical qualities responsible for speed decline with age but remain trainable.
This third step leads us somewhere different.
The useful question is not:
“I’m 65. What clubs should I play?”
Nor is it simply:
“I’m 65. How should I swing?”
The question should be:
“What has actually changed in my golf over the past ten years?”
If the answer is speed, train and adapt what can be trained and adapted.
If it is strike quality, work on strike quality.
If it is launch conditions, find out why.
If your equipment no longer makes efficient use of your swing, change it.
And if several things have changed, do not look for one solution to a problem that has several causes.
Ageing in golf requires adaptation.
But first, measure what actually needs to be adapted.
