[Closed] Help me convert

OK so im thinking of trying 9 speed double and bash as i dont use the outer ring of my triple set up that often... So my question to the educated masses of STW are

what will i need (if it is possible) to convert my XT M770 cranks into a double set up

is it as simple as getting a chain guide, bash guard and a new middle ring and then removing the outer ring, and adjusting the front mech stops

im thinking of keeping the granny ring 22 teeth....buying a 34 or 36 tooth for the other......

target bike is a spesh enduro 2010

thanks in advance
