Snow Biking in Japan

cycling training on snow with road racing bikes with studded tires

Mikuni Pass 23

Temperature: minus 23 degrees Celsius in the KTV (katabatic valley) and minus 21 degrees Celsius at the Mikuni Pass

It was a radiative cooling. He used ski goggles with heating lenses on the climb. The road was covered with hard ice and thin layer of compacted snow. Entering the bottom of the cold air lake, the pedals became heavy. The grease of ball bearings must have frozen. Moreover, the oil must have congealed although he changed the oil into cold resistant oil after Mikuni Pass 13. So the brakes became heavy as well. After reaching the summit, he did the interval training during the descent.
