Inner race from the inner freehub bearing has become detached from the bearing, so you can see the ball bearings loose within the freehub (the freehub itself is fine)
Rearwheel #2, let a little too much air out before engaging the black diamond Haideralm trail...Tried to use a rock as hammer but that didn`t work. After inserting a tube I was able to make it down mountain on the so-called blue Haideralm flow trail (which is far from blue or flowy)
