I can see how tricky the SH56 can be for people who do gravel and mountain biking. I ride on-road most of the time and am admittedly very clumsy, so being able to unclip quickly to avoid falling comes in handy.
SH51 will release on a sharp upward pull before your bones snap in a crash, like ski bindings.
I didn't know that. I suppose that's a safety feature.
