Many experienced riders ‘just know' when it is time to replace the chain, but there are a few tests that can help assess chain condition if you’re not so sure:
The rollers should not be loose, but rotate freely without too much side to side movement.
There should not be excessive lateral play in the chain. That is, if you grasp the chain and twist it about a an axis perpendicular to the ground, there should be an amount of give but no sloppiness - try reciprocating the action to be sure.
If you try to pull the chain away from the rear sprocket at the point furthest away from the front sprocket there should be no more than 3 or 4 mm of movement.
If you have run out of adjustment on the chain, you could remove two links and rejoin the chain. We don’t recommend this, though, because a chain that has worn this much will have grown in length so much that it will be wearing your bike’s sprockets badly.
