>>1050635>The links did get stiff in the exact same manner (and possibly same cause) on a previous chain, that I am certain of.That's irrelevant.
>On this new chain I'm getting the same symptoms, but won't risk excessive chain wear to ride enough to cause the stiffness if there's no need for it.Actually, more chain wear is likely to _fix_ the issue, not worsen it. I have in fact done exactly that once when the problem was very slight, just on one or two cogs, and I knew the cassette was just very minimally too worn - I pedalled softly for the first few hundred miles and waited for it to go away.
>Crankset got replaced mostly because people here said it was a huge no-no to put new chain on old cogs.Yes, it can cause chain suck. Which on road chainsets with profiled teeth usually takes a fuckton of wear and even then only manifests very rarely.
>Plus, upon further inspection, the chainwheels had broken-off teeth due to wear.No, it had aids. Shift aids. Or ramps - whatever you prefer to call them. Broken teeth doesn't happen in the real world.
