The most important thing to remember when putting drop bars on a mountain bike frame is to make sure that you install those bars much higher than on a road bike or a cross bike and the only way to accomplish that is to use a fork with uncut steerer tube and maybe a shorter stem. or a high rise stem.. MTB frames have a different geometry and the only way to make it work is to get those bars higher up...I speak from experience, I have two different mountain bikes set up with drop bars.
