How do I know if my bike chain is too long?

Do a simple check on your bike by shifting the chain to the big chainring and the biggest cassette cog; then, push on the end of the derailleur cage (pushing forward) to see how much it will move forward.

75% of its original length. If you put the tool up against the chain and it doesn’t reach the 0.5 mark, then your chain has not elongated and is fine.

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.
