Just installed a deda dog fang after getting sick of dropped chains and had my first experience of it in action yesterday. So was naturally shifting from big ring to small and the chain just jammed. Eck, I thought, and stopped by the side of the road and had a look. It all looked fine, gave the pedals a spin, and it worked perfectly. So is this how they work? The chain jams up against the chain catcher, and then you wait and pedal again and it's fine?
I'm not sure it's supposed to jam. It's supposed to either sit next to the chain on the smallest ring so it can't shift down further. Or if the chain comes flying down off of the big ring and misses the smallest, it will sit on the hook of the catcher so you can turn the cranks and nurse the chain back into place.
