Upgrading from 8 to 9 speed

[Moab]

Hypothetical idea: I may want to change to 9 speed sometime on my mtb. These are the parts I have on my groupset, what do I need to change, and what can I still use?

 

LX Crank (44-32-22)<?: PREFIX = O />

LX F. Derailleur

XT R. Derailleur (normal rise)

LX cassettes (11-32)

Saint Sti disk shifters

[Mudsimus]

Those are all supposed to be 9 speed.

[Conti]

you only need 9 sp shifters, cassette and chain

[Moab]

Those are all supposed to be 9 speed.

 

So what? change the cassette and chain? as easy and cheap as that?

You will need 9 speed shifters and a 9speed RD.

no need to change the RD
