I have a similar situation, except I have a threaded steerer which is too long, so want to use it with an ahead stem rather than a quill. Can I trim back the steerer to size then install as an ahead style?
Sorry to hijack your thread.
I'm no engineer but I'd personally be perfectly comfortable clamping a stem on that steerer. Don't clamp it onto any part of the threaded section though. Material has been removed to cut the threads and it will not be as strong.
