First, this is a follow up to this: Why does my back wheel keep becoming untrue?
(The short version is I bought a used bike a few weeks ago, I broke a spoke on the back wheel, replaced the spoke, trued the wheel with a tensiometer, and found that it had become untrue again. The diagnosis was either the wheel was bent, or that the spokes were just settling and re-truing it would sort out the problem.)
I've been riding it over a week with an untrue back wheel (aka Kayak Mode). Today, I checked the wheel because the trouble had become a big issue again, and found I had two (!) broken spokes since replacing the first broken one a week or two ago.
So, why are my spokes snapping like spaghetti? I guess:
- Because I was riding without truing the wheel
- Because I'm riding too hard (i.e. coming off curbs)
- Some combination of the two, or something else.
Your pal, JKD

First, thanks everybody.
I wanted to follow up for people who find this question later, and describe the rest of my experience with the wheel.
I kept breaking spokes after replacing them, and by the time I got to the shop again, I had broken five (!) more. They looked at it, I looked at it, and I ended up replacing the wheel. It rides fine now, and as far as I can tell, it was just an old wheel.
