Abstract
Embodiments of multiple flex shaft systems are disclosed herein. Other examples and related methods are also presented herein.
Claims11
A method comprising:
- categorizing a plurality of golf club shafts into a plurality of categories of golf club shafts based on a flexibility of the plurality of golf club shafts,
- the flexibility of the plurality of golf club shafts determined, while the plurality of golf club shafts are decoupled from any golf club heads, via a flexibility measurement mechanism configured to apply a predetermined force to the plurality of golf club shafts;
- determining a golfing level of an individual being fitted;
- and
- selecting an appropriate category from the plurality of categories of golf club shafts based on the golfing level of the individual;
- wherein:
- a first shaft flexibility range exhibited within a first category of the plurality of categories of golf club shafts optimized for individuals with a high golfing level is greater than a second shaft flexibility range exhibited within a second category of the plurality of categories of golf club shafts optimized for individuals with a medium golfing level;
- the second shaft flexibility range is greater than a third shaft flexibility range exhibited within a third category of the plurality of categories of golf club shafts optimized for individuals with a low golfing level;
- and
- shaft flexibility range differences between the first, second, and third shaft flexibility ranges are substantially consistent relative to each other.

A method comprising:
- categorizing a plurality of golf club shafts into a plurality of golf club shaft sets based on a flexibility of the plurality of golf club shafts,
- the flexibility of the plurality of golf club shafts determined, while the plurality of golf club shafts are decoupled from any golf club heads, via a flexibility measurement mechanism configured to apply a predetermined force to the plurality of golf club shafts;
- determining a golfing level of an individual to which a proposed golf club shaft set will be matched;
- and
- selecting the proposed golf club shaft set from the plurality of golf club shaft sets of different golfing levels to fit the golfing level of the individual;
- wherein:
- the plurality of golf club shaft sets comprises:
- a first golf club shaft set with a first shaft flexibility range and configured for a high golfing level;
- a second golf club shaft set with a second shaft flexibility range and configured for a medium golfing level;
- and
- a third golf club shaft set with a third shaft flexibility range and configured for a low golfing level;
- the first shaft flexibility range is greater than the second shaft flexibility range;
- the second shaft flexibility range is greater than the third shaft flexibility range;
- the proposed golf club shaft set comprises proposed golf club shafts and a shaft flexibility variance;
- and
- the shaft flexibility variance is consistent from shaft to shaft of the proposed golf club shafts of the proposed golf club shaft set.
