With a 200k randonnee planned for tomorrow, I used my randonneuring bike for my commute yesterday and today, just to make sure everything's working. Yesterday, no problems, though I did notice the gears skipped once as I was accelerating from a stoplight a little before I got home.
This morning I got on the bike and immediately found it wouldn't shift at all. Puzzled, I stopped to inspect, and saw the chain was routed through the derailleur wrong. WFT? I was able to ride home to check it out....
Turns out the jockey wheel bolt had got loose allowing the cage to flex a little and the chain had somehow slipped past the jockey wheel. The bolt and the jockey wheel were still there, though one of the little dish-shaped bushings had gone missing.
I dug an old derailleur out of the bins and replaced the jockey wheel. Easy to do at home; had this happened tomorrow, I might have dnf'ed a hundred yards into the ride. Whew!
