I lost four spokes on my morning commute when the chain decided to jump off the big cog. Of course I don’t have a spoke protector. (Who needs a dork disc? Bad things won’t happen if you keep your bike maintained. /s) I was lucky to skid to a stop rather than crash when the rear wheel locked up.
PSA: keep a few zip ties in your repair kit.
I didn’t know this was a thing. I’ve never lost a single spoke. But then I buy cheap stuff that isn’t hyper engineered to the tightest specs.
