I'm looking to upgrade my 8 old Alivio speed setup to 9 speed but a bit at a time as funds are very limited at the min.

I'm going to need a cassette, chain, front and rear mechs and shifters as I already have a chainset that i can use.

Are there any 8 speed compatibe bits that i can use l bolt on straight away without having to collect all of the kit before i fit it to the bike? Deore XT or LX stuff probably.

Any help greatly appreciated and sorry if this has been asked before.
