Make it what you will....
I'm of the opinion that the ML is genetically a trail bike with some Racer-X DNA, but really this bike is difficult to categorize. The ML is a chameleon so to speak. You can switch rear end travel between 5 and 4 inches and if you mate the frame with a travel adjustment fork you could have many different bikes (HTA ranges from 70.5 to 68.5) or you can build it up for a single purpose ranging anywhere from 24 hour racing to more gravity oriented riding (frame will accept a coil over shock) and anything in between.
As an example, I built my ML up as a 27# single purpose, set and forget aggressive cross country trail bike. I have never used it in 4 inch mode and I didn't put on a travel adjustment fork.
I recommend that you look around on this board and you will see how people are building up their ML's and to be sure not one of them is quite like another. Let your imagination run wild!!
