You should also see two slight bends at each jockey wheel of the rear derailleur. If the chain is too short, this shift is difficult to make and the derailleur cage is stretched out and almost parallel to the chainstay. If the chain is really short, then you might not even be able to shift into the largest cog.

Is MTB chain too short?
Registered. If you can’t shift into the big ring/big cog combo, the chain is too short. If it makes it, then it is ok. I have a couple bikes that just make it into the big/big combo and they don’t make any more drivetrain noise than the others.

A derailleur is just a dumb machine, it just does what the shifter tells it to do, so the shifter matters much more.

How do you know if your bike chain is too long?
If the chain is really short, then you might not even be able to shift into the largest cog. Then, if you shift into the smallest chainring and smallest cog and if the rear derailleur pulls the chain back so far that it comes in contact with itself, the chain is too long.
