I'm a year round rider. The coldest I've ridden was -14f/-25c. Good gear keeps me warm and comfortable. I've ridden thru several blizzards and numerous ice storms. I'm good up to 10 inches of snow. After that I go to plan B, which is the quickest route to the main road that will hopefully be plowed. If not then I practice my riding skills by trying to ride down a tire track. In nine years of everyday commuting I've pretty much ridden in everything that Mother Nature throws my way. Winds over 50 mph will stop me in my tracks. And that's happened once.
