I live in a place where it frequently floods. How can I keep my chain from rusting? My poor bike's chain lasted all of three months before it gave in to the winter floods where I live. Storing it indoors is not an option, and despite my maintenance efforts, the knee-deep floods that come once a month or so, rain every other day, and ocean only a quarter of a mile away has made it pretty much impossible to keep my chain dry. It's deteriorated beyond a useable point, so I have to buy a new one now. I'm new to bike maintenance on this level so I'd really like some advice on how to avoid replacing it again in three months.
If you're getting knee-deep floods it's destroying the bearings along with the chain.  You need to hang the bike up somehow.
