The Real Role of Golf Shaft Flex and Kick Point

The Real Role of Golf Shaft Flex and Kick Point

Choosing the right golf equipment won’t instantly make you a pro—but it will set you on the right path. Golf is challenging enough without making it harder by using the wrong gear.

While many golfers focus on club heads, the shaft is often the bigger performance factor. The right shaft flex and kick point can transform your accuracy, distance, and consistency—no matter which club head you use.

Below, we’ll break down shaft flex types, performance impact, and how a launch monitor can help you find your perfect fit.

What Is Golf Shaft Flex?

Golf shaft flex refers to how much a shaft bends during your swing. The right flex matches your swing speed and tempo, helping you hit straighter, longer shots. Too stiff or too soft, and your distance, accuracy, and ball flight will suffer.

Types of Golf Shaft Flex

1. Regular Flex (R)

  • Best for: Average, casual players

  • Swing speed: 85–95 MPH (driver)

  • Benefits: Maximizes distance without sacrificing accuracy for most mid-speed swings.

2. Stiff Flex (S)

  • Best for: Advanced players with faster swings

  • Swing speed: 95–105 MPH (driver)

  • Benefits: Greater control and accuracy; ideal for players who hit drives over 250 yards.

3. Extra Stiff Flex (X)

  • Best for: Professionals and elite amateurs

  • Swing speed: 105+ MPH (driver)

  • Benefits: Maintains control at very high speeds; prevents ballooning ball flight.

  • Note: Using X-flex without enough speed makes it hard to launch the ball effectively.

4. Senior Flex (A)

  • Best for: Slower swing speeds, often senior players

  • Swing speed: Below ~85 MPH

  • Benefits: Whippy and forgiving; easier to swing through at lower speeds.

5. Light Flex (L)

  • Best for: Swing speeds under 75 MPH

  • Benefits: Ultra-light and flexible; helps maximize carry distance for slower swings.

How Shaft Flex Affects Performance

Distance

  • Too stiff: Shaft won’t fully load and release, reducing speed through impact.

  • Too soft: Overloads and releases early, causing high spin and ballooning shots.

Trajectory

  • Stiffer shafts: Lower ball flight.

  • Softer shafts: Higher launch.

  • Tip: If you hit too high, go stiffer; too low, try softer.

Accuracy

  • Shafts that are too soft can twist excessively, reducing clubface control.

  • Shafts that are appropriately stiff for your swing speed tend to be more accurate.

The Role of Kick Point

While flex impacts overall bend, kick point determines where in the shaft the bend occurs:

  • High kick point: Lower trajectory, more penetrating ball flight.

  • Low kick point: Higher launch, softer feel.
    Matching kick point to your desired ball flight fine-tunes your performance.

Using a Launch Monitor for Shaft Fitting

A launch monitor can:

  • Compare two shaft flexes head-to-head

  • Measure swing speed, launch angle, spin rate, and carry distance

  • Show you exactly which shaft delivers the best results

Example: At a pro shop, test two flex options in the same driver. Review the launch monitor numbers to see which one optimizes distance, trajectory, and control.

Get the Right Data for Your Game

Golf equipment is an investment—make sure you buy the right fit. A quality launch monitor, like the Voice Caddie SC4 Pro, gives you accurate distance, speed, and spin data so you can confidently choose the ideal shaft flex.
