Can anyone think of a way to stop a chain shifting off the edge of a bastardised 11 speed cassette that is now a 10 speed? The cassette will be spaced away from the spokes to fill the gap the removed 16T cog once filled. It will be used for a turbo so in theory I shouldn't ever shift that far, but I worry in the middle of some turbo hell I might forget and do it anyway.
Slightly off topic.

Any ideas?
Note: using limit screws is not an option
