to say I was never expecting my bike to break down in this way, ever, at all, is a downright understatement.
the bolts didn't even shear, they just ... weren't there?
I'd just gone downtown to drop most of my emergency cash in the bank so I could be sure I made the start-of-month bills, and this happened on the way home. I'd decided to take the circuitous route and go look at birds in the parks along the river. barely made it a mile that way before... well, it happened sometimes between the bank and this photo, but I didn't notice it at first because I mistook the intermittent rubbing sound for radio fuzz from the radio I was listening to.
fortunately it was the same threads as bolts for my bottle cage, so i could take the second cage off, throw it in the saddlebag, and adjust my plans to go get new bolts from the hardware store
I asked family and the Internet for guesses on what kind of bolt I should be looking for and spot out a guess of M5, and a general statement of half-remembered belief that most bike frames are tapped the same, like how all cameras are ¼"-20tpi for their mounting screw.
there was skepticism, and in fairness there was also some from my own end, but the hardware store would tell all
