Hmm, makes me wonder what everyone considers cold, lol.
Here most mornings when I leave for work the temperature is sitting between a balmy -20C to a cool -35C.
I have to say that this past week it has been beautiful out when I've jumped on my bike to head to work. I think the coldest it was in this past week was around the -25C mark, and the warmest was probably this morning...-10C.
Is this the kind of temp's that you's are referring to when you talk about cold weather riding?
Anyways, my wife caught me with her camera one day not too long ago as I was getting home from work. I posted the video on youtube so people can see what a real engine can get thru in terms of snow.

Hope everyone enjoys it...it's pretty short though. My dogs kept getting in the way, lol.
