[MENTION=26168]High Fist Shin[/MENTION] not a candidate for ultrasonic treatment?

I had another flat when a mile from home yesterday and accepted a rescue. Flats essentially caused by using an 18-25 tube in a 37 tire which should pretty well answer that question for people. Because the tube is stretched 2:1, the least insult causes a hole to tear open like a pin in a balloon. Both flats have started from the channel, not holes in the tire. I've noticed while following this up that most tubes are rated in a 1.5:1 range of sizes and I've resolved in the future to use the biggest tube I can fit in the tire.

I'm done for the week. I had to deliver dogs to the vet this morning and my new 32-47 tubes are still in the mail. (this fat with a long Presta valve is kind of an obscure size and shops don't stock it.) On the plus side, I got a free Fitbit to participate in a medical study, and I discovered that dirt-cheap 12 gram CO2 cartridges from the pellet rifle section at Walmart will work in the Slime-branded inflator I bought the other day. No commuting next week due to road trip, though there might be mtb'ing in Soquel Demo - really looking forward to that.
