Really there's not much more to say than the title with this one but we think that guy who rode down a dam has finally been trumped.

Fabio Wibmer takes his trials bike along a railing on top of the Koelnbreinsperre in Austria, which just happens to be 200 metres up. He also does it in the snow, can you imagine if there was a small patch of ice on the rail?

To be honest we're surprised his massive swinging balls didn't unbalance him. It is frankly ridiculous and all we can say is don't try this at home.

For more Fabio check out his granny bike downhill video from last week here. He's on a roll!
