It sucked. Almost there, I hear my rear rim rubbing and stop to find that my rim has collapsed! Argh. This is a Sun CR-18 36-hole rim that was supposed to be bomb-proof. Well, I guess I've ridden it about 5 days a week for the last 2-3 years so it has taken a beating. To get the rest of the way to work, I had to remove the rear brake pad on the crunched side and hobble on the sidewalk. By the time I got to work, about a six inch strip of rim had peeled off, was clinking against the chainstay and the tube was completely bulging out of the tire. How it didn't pop, I'll never know.
