I'm with trekkie on this one. I have a 1994 trek 820 that I'm finally replacing this year. Not because it's broken, but because I grew out of it a few years ago (still kept it for short commuting during college). The last few years I've kept it outside during for long periods of time and not given it a second thought. The chain rusted but otherwise the bike keeps chugging along. Mind you this bike was my only form of transportation for many years. It must have thousands of miles on it. Some cheap bikes will perform forever.
