sick bike let me say first off but im pretty sure that is not good for the frame, just sayin i mean 6.7" of travel in rear? this thing is made for 140-160mm of travel in front, more may very well kill it. especially if you ride hard. you might as well have put it on a cross country bike.
you can tell it is bad becasue the little basket looking thing on the bottom of the shock, is normally about flat, here you can tell it is at and angle.
