From Danny MacAskill to Chris Akrigg, we've reported on a lot of videos here on road.cc that feature riders pushing themselves - and their bikes - beyond the limits of what should be possible.
But, it's no exaggeration to say that the one who time and time again leaves us with our hearts in our mouths is the Italian former UCI Trials champion - and high school IT teacher - Vittorio Brumotti.
Some videos are done with smoke and mirrors (and risk assessments, and suchlike).
But Brumotti's scare the living daylights out of us.
Not one to try at home. Should your home happen to be on top of the Grand Canyon.
Nor if it's near a bridge in Utah for that matter.
