As someone deeply involved in fitting and testing golf equipment here at Stafford Golf Store, I’ve helped countless players, especially senior golfers and mid-handicappers—navigate the confusing world of shaft flex options. One of the most common questions I get is about senior vs regular flex shafts.
Let me be clear: the right choice isn’t based on age but on how you swing. Your swing speed, tempo, and control all determine which shaft delivers the best performance for your game.
What Is A Golf Shaft?
A golf shaft is the long, narrow part of a golf club that connects the grip to the clubhead. It plays a significant role in how well you hit the golf ball. The shaft helps transfer energy from your hands to the clubhead, affecting how far and straight the ball goes. Golf shafts come in different types, like graphite shafts or steel shafts. The shaft flex, weight, and length are key factors that impact your swing speed and ball control.
Choosing the correct shaft flex helps senior players and average golfers improve their golf game.
Types of Shaft Flex
Golf shafts come in different flexes designed for varying swing speeds. Regular flex suits swing speeds between 85–95 mph and offer a stable balance of power and control. Senior Flex (or A-flex) is softer and lighter, suited for slower swing speeds (around 70–85 mph). It allows easier clubhead speed and better launch angles. Flex consistency may vary by brand, so professional fitting is essential.
What Is Senior Flex In Golf Clubs?
Senior Flex, also called A-Flex or lite Flex, is a golf shaft designed for players with slower swing speeds, usually between 70–85 miles per hour. These shafts are lighter and more flexible than regular shafts, which helps generate more clubhead speed and distance. Senior flex shafts are often made from graphite, a lightweight material that is easy on the joints.
They’re perfect for senior golfers, beginners, or anyone needing help getting the golf ball airborne with less effort.

What Is A Regular Flex Shaft?
A regular flex shaft is designed for golfers with a swing speed between 85 and 95 miles per hour. It balances control and distance well, making it a popular choice for average and weekend golfers. Regular shafts are stiffer than senior flex shafts but provide enough flexibility for smooth energy transfer. This golf club shaft helps maintain accuracy and is ideal for moderate swing speeds.
It’s a strong option for players looking for consistent performance without going too stiff.

Popular Shaft Flex Types and Swing Speed Ranges
| Shaft Flex | Typical Swing Speed (mph) | Player Profile | Key Features | Example Brands/Models |
|---|---|---|---|---|
| Senior Flex (A) | 70–85 (often 72–83) | Senior golfers, slower swings | Softer, lighter, more flexible, higher launch | Fujikura Vista Pro, Graphite Design AD DI, Aldila NV 2KXV, KBS Tour 90 (light steel)1467 |
| Regular Flex (R) | 85–95 (often 87–94) | Average swing speed, most golfers | Balanced power and control, moderate flexibility | Available from all major brands |
| Stiff Flex (S) | 95–105 | Faster swings, advanced players | Stiffer, more control, lower launch | All major brands |
| Extra Stiff (X) | 105+ | Very fast swings, strong players | Very stiff, maximum control, lowest launch | All major brands |
| Ladies Flex (L) | Below 70 | Slowest swings | Softest, most flexible, highest launch | All major brands |
Senior Flex vs. Regular Flex Golf Clubs
Senior flex shafts are lighter and more flexible, ideal for slower swings under 85 mph. Regular flex shafts are slightly stiffer and better for players swinging in the 85–95 mph range. Senior shafts provide improved distance and forgiveness for those losing speed, while regular shafts maintain control and stability for average players.
Clubhead Speed for Senior Flex Shafts
A senior flex shaft can significantly improve your performance if your clubhead speed is 70–80 mph. These shafts bend more during the swing, helping generate additional club speed and ball flight. For most senior golfers, the increased flexibility compensates for reduced physical strength, helping maintain a consistent game.
Shaft Weight
Weight matters more than most golfers think. Senior flex shafts are typically 30–50g, offering a lighter option that helps with faster swings and less fatigue. Regular flex shafts are heavier (often 55–80g) to match the power of faster swing speeds. Even a few grams can change swing tempo and accuracy.
Why Swing Speed Matters
Swing speed is the most critical factor in choosing shaft flex. Golfers with slower swing speeds need a more flexible shaft to get the ball airborne, while faster swingers need stiffer shafts for accuracy. A mismatch can lead to erratic ball flight and loss of distance. A professional fitter can measure your speed and recommend the perfect shaft flex.
Material: Steel vs. Graphite
Steel shafts offer more control but are heavier and stiffer, ideal for stronger golfers with faster swings. Graphite shafts are lighter, making them perfect for senior players, beginners, or anyone with joint pain. Most senior flex shafts use graphite for higher swing speeds with less strain.
Flexibility: Key Factor in Control
Senior flex shafts are the most flexible for men. Their soft bend profile helps air the ball for players with slower swings. Regular flex shafts are stiffer and suited for golfers needing more stability and accuracy. Choosing the wrong flexibility can result in reduced carry distance and inconsistent performance.
Weight: Lighter vs. Heavier Shafts
Lighter shafts (30–50g) help golfers generate more clubhead speed and are typically used in senior flex shafts. Heavier shafts (70g and up) can offer better stability and control for faster swingers but may limit distance for slower ones. A proper balance between weight and Flex ensures optimal carry distance and shot dispersion.
Length: Matching Shaft Length To Player
Senior golfers often benefit from slightly shorter shafts, which improve control and reduce fatigue. Longer shafts offer more distance but may decrease accuracy. The ideal length varies based on height, arm length, and swing speed. A club that’s too long or short can cause poor ball striking.
Brand And Model Insights
Top senior flex shafts include the Fujikura Ventus Red, UST Mamiya Recoil, and Mitsubishi Tensei AV. For regular Flex, options like True Temper Dynamic Gold, Project X LZ, and KBS Tour are standard. Each model has its torque, weight, and flex profile—fitting matters more than brand loyalty.
Senior vs Regular Flex: Key Differences
| Feature | Senior Flex (A) | Regular Flex (R) |
|---|---|---|
| Swing Speed | 70–85 mph (72–83 mph common) | 85–95 mph (87–94 mph common) |
| Flexibility | More flexible/softer | Less flexible/stiffer |
| Shaft Weight | Lighter | Slightly heavier |
| Launch/Spin | Higher launch, more spin | Mid launch, balanced spin |
| Ideal For | Seniors, slower/relaxed swings | Average golfers, moderate swing speed |
| Example Brands | Fujikura, Graphite Design, Aldila | All major brands |
Note: Flex ratings and swing speed ranges can vary slightly by brand, so professional fitting is recommended for optimal performance14567.
What To Consider When Buying A Flex Golf Shaft
When choosing a golf shaft, consider:
Swing Speed: This is the most critical factor. A senior flex shaft helps generate more clubhead speed and distance if you have a slower swing speed.
Material:
- Graphite shafts are lighter and absorb vibration—great for senior golfers or those with joint pain.
- Steel shafts are heavier and offer better control—suitable for stronger players.
Weight:
- Lighter shafts (like in senior flex graphite shafts for irons) help improve swing speed.
- Heavier shafts are better for stability but can reduce speed.
Flex:
- Use Senior Flex if your swing speed is below 85 mph.
- Choose Regular Flex if your speed is between 85–95 mph.
Feel & Comfort:
- The shaft should feel smooth and comfortable during your swing.
- Trying different options helps find the right balance of control and distance.
How Do I Choose the Correct Golf Shaft Flex?
Use a launch monitor or consult a professional fitter. Know your driver’s swing speed and average carry distance. Senior Flex is likely best if your swing speed is under 85 mph. Between 85–95 mph, regular Flex may offer better control. Pay attention to how each shaft feels during your swing—comfort leads to confidence.
Swing Speed vs. Shaft Flex
Here’s a quick guide:
Swing Speed (mph)Recommended Flex
Under 70 Ladies or Whippy (W Flex)
70–85 Senior Flex (A-Flex)
85–95 Regular Flex
95+ Stiff or Extra Stiff
Senior Flex Golf Shafts with Mid or High Kick Point
Some senior shafts have a high kick point to lower trajectory, which is excellent for players who hit too high. Mid-kick points are more balanced and common, promoting higher launch and moderate spin. This affects shot shape and distance consistency.
