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. "The chain broke, and I was like, 'No, not today.' We got air in the tires, so we're getting it down," said Gwin, referring to last year's race at Leogang, when he rode most of the course on a flat rear tire.
Already dubbed the "greatest UCI World Cup Downhill race victory of all-time," the event's commentators could hardly contain themselves during the improbable run. Luck did play a role in Gwin's victory. Had the broken chain jumped into his spokes, he would have skidded to a halt. Gwin also credited wind and the course's near-continuous drop, which requires little pedaling. Still, the American had to beat the likes of defending world champion Gee Atherton (whom he bested by almost three seconds).
