So, if the measurements are right, a somewhat extreme method would be to cut the top bar clamp off, install a star-spangled nut into the post and use any mtb stem. But with this method, the post height will be about 3-4cm shorter than before accounting for the loss of the bar clamp..
I'd contemplated same strategy, orginally thinking of mounting a suspension stem. But besides shortening the stem, mine is tapered the entire length, not tons, but enough that perhaps a clamped stem there will be tight at the bottom but air gap at top. I may have same issue with double clamps on my current handlebar, based on long gradual tapers between center diameter and at the grips.
