- Over time the shift cables become stretched, in short, the cable becomes loose. There needs to be tension in the cable to open a derailleur, which shifts your chain between gears.
- There would be an issue with the chain being too long, if so it will have a tendency to fall off when riding.
- Could just be wear and tear and parts need to be replaced.
- There is misalignment, as there could be an incorrect installation on the derailleur, or cables need readjustment.
- There could be damage to the sprocket, derailleur, chain, or cable.

The clicking sound is most likely caused by the chain rubbing against the cage derailleur. There are two possible reasons why your bike chain is clicking. The first is that your chain and derailleur may need lubrication.
The second reason is that you are changing gears, making your chain jump up or down a gear on the rear cassette. The could be just the derailleur that needs adjustment.

While on the other hand if the chain is too short it can bind and do a lot of damage if you shift it into a chainring and cog.
