I am going to be getting a bike and commuting soon, and based on this last week, it looks like I may have to ride through a decent amount of rain. My building also won't let me bring my bike inside, so it'll probably have to be outside for most of the day.
What sort of maintenance should I do often to make sure the rain isn't getting to it? What can I do to keep the rain from messing it up in the first place?
