10 speed road chain

[Sterad]

Chaps, can I use a 10 speed chain on a nine speed system/cassette? I have just replaced my old 9 speed cassette, my chain is also a bit old so think it needs replacing too, so can I use a 10 speed chain on it or does it have to be a nine speed chain?

You need a 9 speed chain. 10 speed chains are thinner than 9 speed so you could have shifting problems.
