I ride hardtail mountain bikes in Central Kansas. I ride typically 20-25 miles per ride. We have ice, snow, slush, salt, etc.

I ride the same bikes in the other months as in the winter. I don't do anything different in the summer than i do in the winter for the most part. I run Nokian studded tires in the winter, and other than that, the bikes get treated the same as they do in July.

I wash them if they are extremely dirty, but other than that i just replace stuff when it wears out.
