Shaft flex
The manufacturer’s designation for how much a shaft bends.
Flex is a manufacturer’s description of how a shaft bends. Labels such as Regular, Stiff and Ladies help identify a configuration, but they do not form a single measurement scale across all brands and shaft models.
What a flex label can tell you
| Field | Use it to check |
|---|---|
| Flex label | Which configuration is being sold |
| Shaft material and weight | More of the shaft specification |
| Club length | The length of the assembled club |
| Handedness | Whether the listed club fits your playing side |
Two clubs both marked Regular may still use different shafts. Matching the label alone does not establish that they will feel or perform the same.
Keep the whole configuration together
A product name can cover multiple lengths, flexes and handedness options. When reading a price, check that it refers to the same configuration as the specification table. A stock label should not be treated as a custom fitting.
Choose through a fitting
Judge strike, ball flight, consistency and feel with the actual club. A simple speed category does not capture the full swing or identify the best shaft for every player. Check the specification of the actual club and try it before relying on a promised distance gain.
