Downhill World Cup 2014: Aaron Gwin's Heroic Run With No Tyre!
He can ride faster than most with just one wheel!
UPDATE: Unfortunately the UCI removed the original video embedded in this post from Youtube, but if you skip to 3.23 in the official highlights here, you can see Gwin's incredible run.
Aaron Gwin suffered a fatal flat tyre right at the start of this World Cup run - but the heroic American went on and finished anyway!
Just check out how fast he's going on that second half. Truly impressive stuff from Gwin. Quite possibly the most impressive "stuff" competitive mountain biking has seen all year.
