I broke another spoke on my bike. I guess after 5,558 miles, these things are bound to happen, but it's still annoying

@MLE_online can I see the break?

@RueNahcMohr no. It's not easy to get my phone in there. Why do you want to see it?

@MLE_online I'm curious about the failure mode.

@RueNahcMohr It broke off right where it bends and passes through the hole in the hub

@RueNahcMohr It will probably be wear or embrittlement. I've never seen a broken spoke that looked like tension or torque

@RueNahcMohr here you go! This is the best I'm going to get without getting my usb microscope out

@MLE_online @RueNahcMohr That looks like fatigue. Where would fatigue fall in to the wear/tension/torgue/workload/embrittle categorization?

@poleguy @MLE_online @RueNahcMohr Looks like the "embrittle" notation to me! That's... old spoke, too many potholes (IMHO).

@ai6yr @poleguy @RueNahcMohr So many potholes. Potholes every day, every street
