Here's what a winter's worth of biking looks like: Rusty. My poor derailer is going to get some TLC tonight at Re-cycles, the fix-your-bike-youself-place with a helpful technician (in my case Mike). (I would link them, but it is doubtful they have a web page.) I bought a new chain and new cog for the back tire so soon I will have gears again (woopi!) and it will be fun to learn how to fix a bike....and people won't point and stare are my squeeky chain.
