Now this was embaressing...
Yesterday's rides to and from work were some of the worst I've had in months. After a long while with no mechanical problems to speak of, I had a light wire break, one of the screws holding the disk brake mechanism fall out (that makes the brakes pretty much worthless and is very noisy), and had the seat come loose from the frame attachment. All of these were dealt with when they happened (except the brake thing -- I had to get a new bolt for that), but there was one other thing that just put the icing on the cake.
I was starting up a hilly section of my ride. As I was ascending the first hill, my right shoelace apparently came untied and was caught up by the front chainring. I didn't know this until the lace had made a few revolutions, wrapping itself around the crank a few times. My first realization that this had happened was when the lace tried to pull my shoe (and foot) off the pedal. Now remember that I was going uphill. I couldn't pedal forward any more, as the lace was wrapped pretty tightly around the crank. I was able to get a few back revolutions, loosening the lace a bit, but I couldn't get it all the way loose before I lost my momentum entirely. The result was that I pretty much coasted to a stop and fell over on my right.
I imagine this looked pretty comical from any point of view but mine. Kind of like the guy on Laugh-In that rode a tricycle and tipped it over. My point of view was far less amusing.
It's probably a good thing that the area is pretty much condos under construction. After untangling myself (and my shoelace) and getting the bike back up, I felt free to loose a rather colorful and unrestrained string of invectives. I felt a little better after that. Sometimes you've just gotta yell it out of your system.
