Following a Graubünden icon - the Rhaetian Railway - takes you from imposing Benedictine Abbey of Disentis down into the valley; there are a few sharp inclines to master. After the turn, the Rhine side: pure gravel fun in a constant up and down as if on a roller coaster, and finally a short, fun single-trail descent.
