Winter MTB riding with a fixed gear cyclocross bike [HD]

Winter snow offroad cycling (-14°C) with a cyclocross fixie bike, local forests and woods in Oulu, Northern Finland. Recorded with a GoPro Hero, with a chest mount, 6th of January 2011. It’s minus 14 degrees Celsius, that should be about 7 degrees Fahrenheit..? As for the speed, the whole video is at real speed. You can count the cadence if you wish, that’s quite easy since you see the knees quite often ;) The bike is a 2009 Cotic RoadRat with 30mm Michelin Mud 2 front tire (no spikes) and Schwalbe Marat
