I have a suspicion that the light was knocked loose because I had a large seat bag, so the bottom rested on the top of the rack, and when I was going over the road patches, the bottom of the light was bumped enough that it popped off. Fortunately it made a lot of noise rolling merrily across the busy 4 lane highway so I was able to retrieve it.

But...all that is moot now, since P-clamps have come to the rescue! Thank you all who suggested them. I actually had some leftover from a non-bike project, and the 3/8" were a perfect fit!


The PB Blinky 5 Rack light I had on my Schwinn Tempo mounted perfectly to the P-clamps. They can be moved and adjusted easily, but stay where I put them, even more firmly than my innertube kludge. I've had to pass up on the more elite light systems before, because my roadbike didn't have eyelets/mounting places in the right spots, but no more! This changes everything!

Other things wot I did today - put on the Schwalbe Marathon plus tires (accidentally got 700cx32mm instead of 35 mm, but they work fine, and they're 4mm wider than the 'Dillos I've been using on my Schwinn.) You can see the reflective stripe in the photos. I also installed Zefal rim tape, since upon taking the tires off I discovered that there wasn't really any sort of protection inside the rim for the tube. I put on the SpokeLit lights, and mounted a super shiny Zefal bidon cage.



Unfortunately in getting my rear wheel off, I managed to strip the right cap nut pretty severely. I was able to get it off with my pedal wrench, but I'm worried about being able to do it with the smaller wrench I keep in my repair bag. Going to order a new one from Niagara, hopefully I don't get a flat before it arrives!
