We do not know the failure mode. I was not shifting at the time. I was in the 34/25. The 25 is the largest cog on my rear cassette. The der could have just broke or I hit something that went into the chain causing the chain move toward the spokes. I was on a mountain road near the edge at the time. I do not think I hit anything but on this climb, there is a lot going on with traffic, narrow roads and climbing.

When I inspected the bike, the chain was between the 25 cog and the spokes and the rear der was laying on the chain stays and I did not see and sticks / debris.
