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 have a 50 or 52 on the back of my bike and its a decent amount bigger than any dork disc I’ve ever seen. They seem to only go up to 34 and I have been thinking of 3d printing one that matches my colour scheme.
