    how can you tell if you need to replace your chain on your bike apart from going to bike shop and asking them?

    I usually use a ruler to check for stretch.

    if the chain is badly worn, it can skip and wear down other components, such as the teeth on the cassette and chainwheel.
    you can also measure your chain; chains stretch as they wear - the likes of halfords stock chain wear tools, but it's possible to diagnose it by measuring your chain or using other rule of thumb measurements such as whether you can pull the chain away from the chainwheel on your bike by any significant amount.

    however, i suspect a simple rule of thumb applies - if you think your chain is worn, it probably is.

    With a chain checker:

    Much easier than farting around with rulers.

    Chain Checker here too. Although even then, don't check as much as I should!

    Chain checker, or look at how it sits on the chain wheel and cassette, if it doesn’t sit down fully it’s time to change it.

    Came back from club spin yesterday noticing one of my chain links is bent causing chain to skip.

    I can bend it back/replace the link, but do I ideally need to just buy a new chain?

    This. I tend to check it when shifting starts to deteriorate and know the chain is on the way out once it gets a bit rattly / loose. I usually use the old chain to measure the new one where the old chain is about 1/2 a link longer.

    Chains are cheap. Just replace it I'd say.
