9sp rear mech on 8 speed

[wrinkleygit]

looking thro my shed stock & came across a spare xt m750 rear mech which I'm sure is a 9 speed, can this be used on an 8 speed set up ( obviously with 8 speed shifter), any ideas on this , thanks, mike b.

Yep, no difference - same cable pull ratio.

Yes.

Use a 9spd chain though as an 8spd chain will be a bit thick through the jockey wheels.

9spd chains have the same inner width as the 7/8spd chains and work lovely with 6/7/8spd cassettes

that's a useful tip on the chains, didn't realise that, thanks, mike

I find 8 speed chain runs fine.
