Jun 23, - Is your bike chain loose? Is it coming undone while you ride? Check your chain out. It should be tight enough that it only allows you to move it.

If the rear sprocket does need replacing bike chain tension adjustment off the front sprocket cover and inspect it too. If it passes those tests, the process is then the same as checking chain tension, only you must do it over the whole length of the chain.

Mark where you started with a blob of white-out or grease on the side plate. If the slack measurements vary by more than 10mm the chain needs replacing. Make sure the sprockets are good before doing so.
