Today, Friday the 13th was a little cooler then normal at - 28 Celsius, (- 18.4 Fahrenheit). My 23 year old 8 speed winter bike carried me the 8.4 kilometers to work without shifting issues, ( I tried a fixed gear bike and you can have it). Today like most days I do not need to register on a ride to work winter site because that is just what I do. It is no big deal, really. It would be like having a "Wear your underwear to work day". Maybe to some it would require a extra special commitment but not to me.
