There I was thinking that our local descent of the Dent de Crolles by the Pas de Terreau was pretty gnarly on an MTB but in July Johannes Pistrol completed a descent of the Steinerne Rinne from Goinger Halt and he brought back the film to prove it.
The upper section from the summit down to the upper rinne is relatively straight forward, albeit slightly exposed. The lower section is far out, now Johannes didn't clear all sections but apparently is the most ridden so far.
