“A theorem, once proved, is obvious.”

That’s a quote from one of my graduate school professors — ahem — a few decades ago. The quick-release for the axle was the easy part. But then the wheel doesn’t come off unless you can spread the brake pads. Another online search. Aha. Such a simple design for an important safety feature! In the photo, the brake caliper has been released from the brake cable, allowing the pads to be spread enough to allow the rim and the tire to pass by. Now that I’ve seen how the brake cable is attached, I’ve seen the proof of the theorem and it is now obvious. Right you are, Prof. Stein.

Today I got the wheel off; next, remove the tire and tube to check the tube for puncture(s) or leak(s).

In going back through my text messages with Rich, I am reminded that this process followed my strategy in solving Excel spreadsheet problems. I have a guru I consult when I can't solve an Excel programming problem, but I try to solve it myself before I go whining to him. (His willingness to help is based partly on this knowledge: he knows I’ve explored and searched for a solution on my own.)

In the case of Clare’s flat tire, Rich assured me that I didn’t need any special tools and I wouldn’t have to adjust or calibrate the derailleur at the back end. With that assurance, I went to “The Google” to learn from some of the many people who seem to have nothing better to do than make videos about how to do things. (Yes, I know they make money this way, but one has to wonder how this works out per hour of recording and processing and uploading…)
