There was a Severe Wind Advisory for SoCal so I thought about not riding, but when I peaked out the front door this morning . . . yeah, there was a bit of a breeze, but nothing to get worried about.
Took off in 55deg.F temp. then about 1/2 way to the Metro station got a serious, instant flat rear tire. Just as I was thinking "Have to find out what caused this!" I saw a silver metal-working screw sticking out of tire between the sidewall and the main tread. It was an inch long and I had to un-thread it from the tire! "Yikes" thought I.
In the end, not that bad. Put in new tube, didn't even have to boot the tire. Pumped up tube (gotta love Presta valves!) remounted tire, re-installed wheel/tire, re-hooked-up the Nexus shift cable-nut, put tools back in bag . . . probably less than 10 min. lost. Still made the 6:10AM train (usually catch the 6:00AM train), so no worries really.
When I got to work I used the warehouse Joe Blow pump to pull it up to 85 psi. (My hand mini-pump got it up to almost 60 psi.) so now it's ready for the ride home. Have yet to see if the tube is patchable; suspect not based on the size of the screw!
