  1. How can you tell if a chain is on it's way out? I know adjusting it is a sign, but waht are the other signs?

  2. Chains don't stretch evenly all the way around and end up losided, one section of, say, 20 or 25 links longer than another by 20 or 30mm. This is what makes them unserviceable.

    Put the bike in neutral, lift the back wheel off the ground and spin it with your hand. If the return run has the spec amount of slack (20-25-30mm) on one section of chain, but three times that on another section, time for it to be pensioned off...

    ...which is good, because it means you get to play with an engle grinder.

    In practice, a worn chain will *feel* awful. Riding along, the bike'll lurch ever so slightly as the loose and tight sections of chain alternate on the drive run. If you're really strapped for cash and don't mind putting up with this, you can eke another few thousand km out of the chain when it gets to that stage, but, eventually, it'll end up needing adjustment every couple of hundred km. When that starts happening, you're out of options; bin it and replace it.

    (insert here the standard advice about replacing sprockets together with a chain)
  3. with the chain held tight with 1 hand try lifting the links off the back of the rear sproket, if you can get it to raise more than about half of the spocket tooth the chain is buggered

    it is always best to replace both the chain and sprokets at the same time
