But you only do the adjustment on a threaded headset once. For
threadless, you have to re-do each time you change anything about the
stem. When you remove the stem of a threadless headset, the whole headset
assembly is loose.
Yes, it's simple enough to re-adjust, though I do not like the idea of
trying to adjust the preload if the bearings are not clean and well-lubed.
We have all heard about people who couldn't adjust the preload on their
hubs; I see no reason to presume they could adjust the preload on a
headset, either. For them, raising the bar height means a trip to the
mechanic.
