Bike chain.

My bike chain and gears are incredibly rusty, from my biking to the subway stop all winter (I'm near 2 stops, one is 15 minutes away by foot, the other 20, so I usually bike to either, as long as there's not a lot of snow on the roads).

I oiled up the chain and riding is easier, but it still looks rusty.

I'll have to take my bike in for a spring tune-up, and I wonder what the bike people will say.
