Slide down the snowy mountain and update the world record of the mountain bike

An Australian Markus Stoeckl gave a mountain bike 130.7 mph (about 210 km / h) and repainted the world record. It seems that this speed was given by sliding on the snowy mountain in Chile which has a slope of 45 degrees, but how did you brake it?

This is the movie when I got a record. I think that it is for speed up and safety, but I am wearing a helmet like helmet with a suit feeling very unpleasant.

Markus Stoeckl has a height of 6 feet 4 inches (about 193 cm) and weighs 220 pounds (about 100 kg) since he was young, he heard that Hercules and a nickname were attached. The previous highest record was eight years ago, and this time it exceeded the record by 14.0 mph (about 22 km / h). Because the temperature is very low, Markus Stoeckl seemed to have to hold his breath for 40 seconds while gliding so that the helmet will not cloud.

By the way, in the case of Eric Barone who slipped on the ground and issued a record of 172 km / h, the bicycle could not stand the shock and fall apart. He seems to have broken the whole body, but the record was left because the bicycle broke down after reaching the maximum speed.
