The Guide to Shaft Flex: Understanding Tensei Golf Shafts CK vs AV

Introduction to Tensei Golf Shafts

Golf technology continues to evolve at a rapid pace. The equipment and accessories market has expanded at an extraordinary rate. Golf clubs now offer so many customizable facets to cater to your unique swing. Just as each individual is unique, golf equipment complements that distinctiveness! This article aims to shed light on the various aspects of golf shafts, diving specifically into the Tensei golf shafts. While there are multiple brands and models in the golf shaft arena, Tensei is among the most prominent and two of their models specifically. There's often confusion between different shaft series, such as Tensei Golf Shafts 1K and AV. Within Tensei, there are two main lines: 1K and AV, each with its own set of models. By the end of this article, you should have a clearer understanding of Tensei golf shafts, an overview of Tensei shafts, and the distinctions between their models. Plus, we'll include a quiz to help you determine which golf shaft would be best for you.

Tensei Golf Shaft Components

Golf shaft in a swing arguably has a greater impact on various aspects of your swing than the clubhead itself. They influence ball flight, ball spin rate, the draw or fade of your shot, and much more. Tensei golf shafts comprise various components, including:


Shaft Flex: This aspect of the shaft is frequently discussed. You've likely heard terms like 'stiff' and 'regular flex'. The stiffness should correspond with your swing speed. For instance, someone with a rapid swing speed wouldn't want a shaft that's overly flexible, and vice versa.


Shaft Weight: The weight of the shaft can either increase or decrease swing speed. A heavier shaft can provide better control for someone with a high swing speed, whereas a person with a slower swing speed might benefit from a lighter shaft to boost their swing velocity.  In turn, it gives you the most optimal driver ball speed.


Torque: Refers to the degree of twist in a shaft. Typically, low torque values are below 3.5, mid-range torque values hover between 3.5 and 5, while values above 5 signify high torque. A greater torque value indicates more twist in the shaft. It's common for heavier and more rigid shafts to showcase lower torque numbers. It's crucial to understand that a high torque value doesn't imply instability, just as low torque doesn't guarantee stiffness. Everyone perceives the feel of a shaft differently, and such perceptions are always personal.

Tensei Golf Shaft Stiffness & Weight

Golf Shaft Flex


Not unique to Tensei, but all golf shafts have a profile of shaft flex and weight.  However, Tensei takes it a step further and each of Tensei's golf shafts will vary in the range of stiffness they offer.


Stiffness profiles are:

L- Ladies Flex

A- Amateur or Senior Flex

R- Regular Flex

S- Stiff Flex

X- X-Stiff Flex

TX - Tour Flex


This is very high-level as there are varying levels within these as well, and from shaft to shaft, the flex will change.  Always best to get a professional fitting to make sure you are leveraging the proper shaft for your swing. As an example of two varying Tensei models, their stiffness profiles are below:


Tensei CK Blue Golf Shaft:

  • Tensei CK Blue Regular Stiff

  • Tensei CK Blue Stiff 

  • Tensei CK Blue X-Stiff

  • Tensei CK Blue Tour Stiff


Tensei AV White Golf Shaft:

  • Tensei AV White Stiff

  • Tensei AV White X-Stiff

  • Tensei AV White Tour Stiff

Golf Shaft Weight 


Each golf shaft has an associated weight, labeled in grams. For drivers, this weight typically ranges from 50 to 90 grams. While the weights usually increase in increments of 5 grams, variations can occur depending on the manufacturer.


Similar to shaft flex, the weight can vary among models. As seen below with the same two shaft examples from the Shaft Flex.


Tensei CK Blue Golf Shaft:

  • Tensei CK Blue 50

  • Tensei CK Blue 60

  • Tensei CK Blue 70

  • Tensei CK Blue 80


Tensei AV White Golf Shaft:
