10 speed shifters with a 9 speed cassette

I have a SRAM 10 speed bar end shifter, rear derailleur and chain. Will it work with a 9 speed cassette? Or is the cassette spacing narrower on 10 speed so the pull ratio won’t work?

take a cog out of a 10 spd cassette and set the limits correctly maybe instead? The spacing is slightly narrower, may still work but probably not as well as it should


What ratio 10 speed cassette do you want/need? I’ve a few lying round in various states of use and no 10 speed equipped bikes to use them on

After something that goes up to 36t. Don’t really care about the small sprocket.

hmmm bit big - I have plenty between 23 and 28 but a 12/30 is the biggest I have
