How to Read a Golf Shaft Spec Sheet — Weight, Flex, Torque, and Kick Point Explained

When you're shopping for a new driver shaft, you're confronted with a wall of numbers: 65g, 3.2°, S-flex, mid-high kick point. It can feel overwhelming if you don't know what any of it means. This guide breaks down every major spec on a golf shaft spec sheet so you can shop with confidence.

1. Shaft Weight

Weight is one of the most impactful specs on a shaft, measured in grams and typically ranging from around 40g (ultralight) to 85g+ (heavy) for driver shafts. Lighter shafts allow you to swing faster, which generally means more distance. Heavier shafts offer more control and stability.

2. Flex

Flex describes how much the shaft bends under load during the swing. The standard rating scale runs from most flexible to stiffest: L → A → R → S → X. The right flex primarily depends on your swing speed, but tempo plays a role too. For a deeper breakdown, read our guide on Stiff vs Regular Shaft Flex — How to Know Which One You Need.

3. Torque

Torque measures how much the shaft resists twisting, expressed in degrees. A lower torque number (e.g., 2.8°) means the shaft resists twisting more. Low torque is generally better for faster swingers; high torque can help slower swingers square the face. Read the full breakdown: What Is Shaft Torque and Why Does It Matter for Your Driver?

4. Kick Point (Also Called Bend Point)

The kick point is the point in the shaft where it bends most:

• Low kick point: Promotes higher launch and more spin — good for slower swingers
• Mid kick point: Versatile option that works well for a wide range of players
• High kick point: Produces a lower, more penetrating ball flight — best for faster swingers

5. Tip Stiffness

Tip stiffness refers to how stiff the bottom section of the shaft is. A stiffer tip = lower launch and spin. A softer tip = higher launch and spin. The Ventus Blue is known for its firm tip section, which contributes to its low-spin, low-launch profile — contrasting with the Ventus Red's soft tip and high launch.

6. Length

Standard driver shaft length is 45–45.5". Longer shafts can add swing speed but reduce control. Unless you've been specifically fit for a longer shaft, standard length is almost always the right starting point.
