Things didn’t go quite as planned. As soon as I shifted gears, I started hearing the chain rubbing against something. The sound seemed to be coming from the rear, but beyond that, I couldn’t tell much. I stopped a few times along the way, but the noise persisted, except at the highest gears. Fortunately, I was still able to get into class almost on time.

I had previously given the bike a cursory inspection and concluded that it hadn’t been damaged in the accident, but this morning, I noticed that, in fact, the derailleur was badly scratched. The scratches, I reasoned, wouldn’t be likely to affect the functionality, but if the derailleur scraped against the ground, something could easily have bent and caused the chain to come in contact with something it wasn’t supposed to. A quick look in a bike maintenance guide suggested that it was probably the hanger that was bent.

I ordered a new hanger after some unsuccessful attempts to bend the hanger back into shape. Until it arrives, I’ll be using my secondary bike or taking the buses.
