Some golf shafts bend more than others, of course. The letter code represented by the letters L, A, R, S and X represents those different grades of flex.
’L’ is the most flexible shaft and ’X’ is the stiffest shaft. ’L’ denotes ’ladies flex’; ’A’ denotes ’senior flex’; ’R’ denotes ’regular flex’; ’S’ denotes ’stiff flex’; and ’X’ denotes ’extra stiff flex.’

Why is senior flex represented by an ’A’? When manufacturers first started using this code to denote the flex of their shafts, ’A’ stood for ’amateur,’ but that level of flex later became associated with senior men.

No, there is no standard that dictates how stiff any given shaft must be in order to be designated as an L, A, R, S or X shaft.
Shortly after steel shafts were introduced in the 1920s, steel shaft makers discovered they could change the diameter and wall thickness of the tubes to create shafts with different amounts of stiffness to better match to the different swing speeds and strengths of golfers. Eventually, the shaft industry developed five different shaft flex designs, designated by the letters L for Ladies; A for Amateur, which evolved into the senior flex; R for Regular; S for Stiff and X for Extra Stiff.

What is interesting is that no standard for how stiff any of the five flexes would be was ever established in the golf industry.

Still today, each shaft maker develops its own definition for how stiff any of its flex levels will be. As a result, the R flex from one company may be the same or different in comparison to the stiffness of an R flex shaft from another company. The same is true for each of the other four basic flex letter codes.

Thus when selecting the right shaft for your swing mechanics and swing speed, it is important to find a clubmaker or sales person who really knows the differences in shaft flexes to advise on your shaft selection.
