Front mech height advice

coblck

Hi there will be finishing build end of week and will be using 2x9 drive setup, my front mech is 3 speed one and wondering what height will i have to set, when using 3 rings its usually between 1-3mm do i still do the same with the new 2 ring setup, will obviously have to set limit screws so wont over shift as well. Will prob work it out but any advice would be gratefully appreciated.

I think you've got the idea. 1 to 3 mm above the larg ring and use the high limit screw.
