Once in a while when the air, and your pedals and cleats are well below freezing, the traffic on the road keeps the road above freezing and it is wet instead of ice. When the moisture from the road hits your bike it turns into ice. Stuff gets frozen once in a while. It only happens to me about once a year. But, it can happen.
