Regular use of a chainwear indicator and chain stretch.

The biggest fault with chain measuring devices is they include roller wear in the total. This is irrelevant in terms of chain extension (wear / stretch). This is also why they often can fail a new chain as roller tolerances vary from make to make. A ruler is more accurate, just as easy and much cheaper.
As for chain baths or not I have found it does not make much difference. The important thing is to keep it clean and well lubed.

Lengthy rants? I thought people stopped arguing on forums years ago. All I can add is that I feel a little bit smug owning a bike with such a cheap groupset....Sora, anything goes wrong or gets worn out and I can fix it with the change down the back of the sofa. Strange but true.

Meh. I can do the same with Dura Ace. Still smug?

I don't understand how it's difficult to get the chain under tension for measurement using a steel rule? Put the bike in 53-11 (or whatever) and set the rule against the top run of the chain - with zero over the centre of the first of 12 pins. Then see where the 12th pin lies in relation to the 12" mark on the rule.

Simples.
