As you all know, I only commute 1.4 miles or so. Let's see. Left 10 minutes later than I wanted to. Front brakes are rubbing and make an annoying hissing/rubbing/sireny sound. Bike computer not working. Rotated it but nada (it's prob. a simple adjustment). Went over a bump only to find my pannier wasn't locked on and down it went. Only the water bottle rolled out and only one student who was walking to where I teach saw I think it must have been locked on but I road down Western just south of Hollywood and that street is a freaking danger zone of bumps and holes, perhaps it swiveled loose. I swear I'm shocked tires withstand city streets at all.
