Emily VelascoI broke another spoke on my bike. I guess after 5,558 miles, these things are bound to happen, but it's still annoying
Rue Mohr@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
@MLE_online hmm, but was it wear, tension, torque, fracture (embrittlement)....
@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 looks like a fracture, can you tell if there is a lot of movement in the spokes when your wheels have load on them?
@RueNahcMohr There's not any significant movement as far as I know. When they can move, there's creaking where they touch as they cross over. I never hear that on this wheel.
@MLE_online well, I will say you have set the record on number of broken spokes for anyone I know.
@RueNahcMohr I probably ride a lot more than most anyone you know
Friedemann Wachsmuth@RueNahcMohr @MLE_online in 8 years of riding my urban bike a lot (about 5000 miles per year) I broke 11 spokes in the rear wheel. Without much load. Reason was apparently the hub design having just 30 spokes (instead of the usual 36?) and the weird angle that causes on them — combined with a bad quality batch apparently. At least, the replacement spokes (same size) never broke yet. It just happens. ¯\_(ツ)_/¯
I suggest pulling 2 random ones and checking them. look for cracks, their hard to see, I'm not sure of a way to enhance them.
@RueNahcMohr Nahhh. I'll just replace this one and keep riding. I don't feel like buying all new spokes and rebuilding the wheel
smells of bikes@MLE_online oh, was the clicking sound while you were riding, a broken spoke whacking something with each rotation?
@smellsofbikes no, it's the wheel bearings. Me lubing the freewheel yesterday must have gotten 3 in 1 oil into the grease and thinned it out a lot
@MLE_online I kinda like that little clickety sound.
@smellsofbikes it sounds nice, but it's probably bad for the balls
@MLE_online muffled juvenile giggling
poleguy looking for lost tools@MLE_online @RueNahcMohr That looks like fatigue. Where would fatigue fall in to the wear/tension/torgue/workload/embrittle categorization?
AI6YR Ben@poleguy @MLE_online @RueNahcMohr Looks like the "embrittle" notation to me! That's... old spoke, too many potholes (IMHO).
@poleguy @RueNahcMohr only Rue can answer that
embrittlement. where its worked back and forth and the metal goes bittle and snaps.
@RueNahcMohr @MLE_online Thanks. Notes taken.
