Watch: First ever mountain bike descent of Corbet’s Couloir

Anyone who has ever skied or snowboarded Jackson Hole knows just how nerve-racking it can be to send it into the infamous Corbet's Couloir, even in the best of conditions. Doing it in icy conditions on mountain bikes is nothing short of insane, and that's exactly what Cam McCaul and Casey Brown did in TGR's latest film, Rogue Elements.

There's a litany of other adjectives you could prescribe to the lines McCaul and Brown threw down - Sketchy, heavy, and borderline suicidal all come to mind - but ultimately, the end result was jaw-dropping.
