Hey everyone

I am finally getting round to building up a Peugeot 531 Pro ("Aneto") frame from 1986 that I bought several years ago.

First step is installing the new threaded headset which has balls captured in cages.

For some reason, I am thinking the correct adjustment here should be a slight pre-loading of the ball bearings.

I seem to remember an idea that this engages more balls in contact as well as prevents any play wearing out the races through repeated micro impacts.

Does this seem reasonable ? (pre-loading the bearings when adjusting the headset)
