I agree that it Doesn't look like the hardest of "all mountain" bikes but having said that I went to the Pyrenees last summer with Altitudeadventure.com and they have Scott Genius' although they tend to ride their newer (burlier) Ransoms most of the time. I think with bikes like this, it's probably as much about the ability of the rider
ie: hamfisted, clumsy fat get with v.little ability (me) = probably not the ideal rider for a Genius
or
talented, experienced former XC racer turned pyrenees guide = Genius will probably cope with pretty much anything barring DH 😀
