What is your response to rust on components? I keep my bike impeccably clean (aka anal), don't ride in wet conditions, and store indoors, so it's rarely an issue for me. But, sometimes I work on friends' bikes, and see rust invading components. Most of the time, it's not in an easy place to sand it off, and put something over the top to avoid it coming back. Do you guys tolerate rust, especially on low end components, or do you recommend replacement? I don't know, maybe I have to lower my standards and abandon the zero tolerance (at least on bikes that aren't my own). 1st world problem?
