Shaft Flex

Flex describes how much a shaft bends under load. Designations such as R, S and X are not standardised between manufacturers.

01 / Why it matters

Flex influences timing, feel and how the head is delivered, but only in combination with weight and bend profile.

02 / Performance impact

The same letter can measure very differently between models, which is why flex alone is a poor specification.

03 / Common misconception

A stiffer flex does not reliably fix a left miss or a right miss.

04 / How TruePath considers it

TruePath evaluates flex as part of a shaft profile rather than as a single letter grade.

Questions golfers ask.

Is stiff flex right for my speed?
Speed is only one input. Tempo, transition and the specific model's measurements matter.
