Missing link 7.3 on 7.1


Can i use a kmc missing 7.3 link on a 7.1 chain as a emergency should the chain break ?

As a new chain will be required in several months & don't wish to purchase a 7.1 link that costs half a chain price !

Bikes an 8 speed housing an older kmc chain of 7.1 as the next chain will be a 9 speed on an 8 speed cassette.

    You could but you may end up with the missing link catching on the jockey wheels or cassette as the pin is a little bit too long. However, it's only 0.2mm so probably won't do any harm.
    If you have nothing else available then go for it.
