So, I just invested some money in a rear fender for my bike, a waterproof jacket, and some waterproof cycling pants. All this stuff will keep me fairly warm and dry during my wet commutes of the late winter/early spring SF bay area season. However, I realized that if it's raining, I would still be leaving my poor Cannondale out in the rain in certain situations (i.e. work, sometimes school, an the gym). I would like to never use my car unless absolutely necessary, but am just wondering what potential damage could be done to my bike (other than being stolen) if it's constantly being left in the rain. Also, what can I do to better maintain it when I return home from my rides?
I have a Cannondale CAAD3 Road/Cross bike.
