Mountain Biker Wins Competition With No Chain On His Bike

Downhill mountain biker Aaron Gwin has pulled off the feat of winning a World Cup race without a chain on his bike.

After snapping his chain in the opening pedal strokes of his run down the course in Leogang, Austria, Gwin continued down, weaving over obstacles, skirting rocks and roots, and landing the jumps faster than anyone in the world.

Aaron Gwin made mountain biking history once again as he raced to a 0.045 second victory in Leogang, Austria.
