I have had my fun for the day.

Yesterday evening went out to the bike to go somewhere and, as I rolled forward, noted a shimmy in the back end(no, not mine; shut up, Og). Rear tire very low, so pulled out the compressor and aired it up. Got there and back, no problem.

Early this afternoon thought I'd check the tire, just to be sure, and found "The pressure, it's not there." As in wouldn't move the gauge. Bleep. Checked the whole tire, no sign of nails, screws, etc., so aired it up again and, hmmm, that his isn't from the slightly leaky chuck, where...

Tire valve. Body leaking right where it goes into the wheel, leaking badly now. So I got to take the back wheel off(not difficult, but a pain in the ass), take it to a shop and get a new valve installed. And no, this is not one of those things I'll try myself if I can avoid it. I've changed tires on my old bike, which had smaller tires and steel wheels; I'm not even gonna think about messing with a tubeless tire on a aluminum wheel without the right tools. Then home and reinstall the wheel, just as much fun as taking it off. At least I now know my rear brake shoes have about 1/3 to 1/2 their life left; be a while before have to change them.

I finally got Security Staff to ride in the front with me instead of in the bed, so she rode along. She sits up watching all, but when I get out to do something and she has to stay in, she gets excited: "Where you going? Why can't I come?!? Come back!" Especially when it's a stop at a place she doesn't remember. At least she doesn't bark, just looks very concerned until I get back.
