Mountain bike speed record holder Max Stöckl is more comfortable than most at extreme velocities, but riding the legendary Hahnenkamm downhill ski course on a bike presented an entirely new challenge for the daredevil from Oberndorf. In order to ride down the 3312 m piste, which runs at a spine-chilling 27% average gradient, the 43-year-old added 15 mm metal spikes to both of his tires for extra traction. Stöckl had previously hit a top speed of 167.6 km/h in Chile’s Atacama desert in order to break the speed record for a standard bike, but taking on the ski hill was still a challenge. “Racing down a straight icy hill is a totally different thing to anything else I have done,” said Stöckl of the run. “It definitely reached and exceeded my expectations. It was more fun than I thought it would be. Coming down the final shoot and jump was a great rush.” The wide open ski track makes Stöckl’s runs appear slow, but he hit a max speed of 106 km/h on the bike. The danger appears more immediate when Stöckl starts drifting to the outside of a long, sweeping off camber corner towards the safety netting on the track’s edge. Watch this two-wheeled run, then tune in on Jan. 20 for the 78th running of the Hahnenkamm downhill ski race on the same slope.
