Ted:
Will I find in your or selected other CR listers' or other engineers'
remarks more on the wear of steel frames? Re:The "soft" , but not in
"softening"
>From the Wikipedia Reynolds tube entry (put here just for newbies like me,)
653 - Was a mixed tubeset which combined tubings of different steels; made up of 753 stays with 653 main tubes and 531 forks [7]. Following feedback from Eddy Merckx that a pure 753 frame was too harsh for certain stages of the Tour de France, Reynolds produced a 653 tubeset which combined 753 stays with 531 main tubes and forks[citation needed]. The 531 used was a thinner gauge than usual, produced specifically for use in the 653 set[citation needed]. Eddy and other riders were very pleased with the result, which combined a light, ultra-stiff and efficient transmission with a more forgiving and comfortable ride[citation needed].

I know you are only reporting supposedly well-informed gossip. But, it is from teen agers and guys in their twenties, few of whom could not have wanted new gear and envied those favored with such.
In the religious wars over frame materials I've just not seen the report you offer here, in passing. For that matter, and this is even on-topic, I asked on bike.rec.tech whether anyone would report having replaced AND DESTOYED a functional aluminum handlebar of many years use, just because it was old enough and used enough to be suspect of being near the end of its fatigue life, and nobody affirmed he had done so.
