When to replace a bike chain

[Wester]

How do you know when it is time to replace your bike chain before it does damage to the sprockets and chain rings . Also which chain would you consider to b e a good quality chain

I have a chain wear indicator and replace @0.75% wear. Some get 2-3 chains out of a single cassette.

KMC chains come highly recommended.

Second the KMC chains. Even with my very modest skills I managed to fit one yesterday with one of the power links that it came with. Easy peasy.

When they're looser than a wino's bowels.

You really need to either buy a chain checker or learn how to measure stretch with a ruler (instructions on the internet).
I thinks its accepted that a chain checker tends to exaggerate the actual wear due to measuring roller to roller instead of pin to pin...but that works in your favour. A worn chain according to a chain checker isnt as worn as you think. So if you replace the chain with that method, you'll extend the life of your cassette and chainrings. Thats what ive found anyway.
105, veloce, sram, I found them all much of a muchness, they all last more or less the same (I used to monitor them for lifespan)

I use Shimano Dura-Ace chains on Shimano.

Change at 0.75 using a chain wear checker, and then throw on the cheapest chain I can find, usually £10 for a 9 speed or £15 for a 10 speed
