I'll have to take my bike home today, but I refuse to think of it as a "Ride of Shame." Shortly before I got to work, pedaling got a lot easier. Checked the gears, and my front derailer is sticking out at about 30 degrees from vertical, while the chain somehow got from the big ring to the middle ring. Looked further, and the derailer is rusted through and the pivot, and the spring is pulling it way inward.
I wore something out. (Again.) I think the ride home will be a Ride of Pride. I'm tougher than my bike!
Anybody else want to share a component failure story?
