ohhh yes. In retrospect, I could have been more adult about that. But all that happened was that the shop just twisted the tube, or otherwise installed the new tires wrong. The mechanic admitted as much to me. Remember, now, that I had to have them do it while I was at work, or I would have done it myself. I've been keeping them inflated to about 110, and they're fine. We're actually talking about the same bike.
