I have an extra 10-speed chain I would like to use with a 9-speed cassette on my mountain bike. Will this combination work ok?


The 10 speed chain is narrower and will work. Not ideal and the shifting might not be as crisp.

Since you have an extra chain you can use it, but if purchasing new I would get a 9 speed chain.

  • Yep. The order of compatibility is 11 speed chain with a 10 speed crankset with a 11 speed cassette works. Everything else works with a higher number of speed will work into a lower speed crankset/cassette. 10 ->9,8, 9->8 – user26705 Jul 7 '16 at 13:22
