9spd cogs are closer together using the same overall distance as 8spd cogs.
rear cog & chain must match.
The derailers are controled by the shifter, so 9spd derailers will work with 8sp shifters.
I'm using XT 9spd derailers & cranks working with 8spd chain, XT shifters & cogs with NO problems.
I think the Deore name started back around 1990, it was 7spd back then.
LX stuff is a good value, less plastic than lower line stuff, works as good as XT & way cheaper than XTR.
