THIS.

I doubt this is what you want to hear but I think you should sell this frameset and wait for one that will allow for the proper saddle high without the stainless top being cut off.

I'm with Dave on this. The wall thickness, and the O.D. of the tube, may not have been designed for what the OP wants to do.

I personally wouldn’t hesitate to clamp on the carbon tube, lots of makers use carbon seat tubes and clamp the topper without a reinforcing like the sV uses.

Speedvagen likely machines that sleeve to a specific diameter, bot I.D. and O.D., not something easily replicated.

If the O.P. is lucky and Speedvagen eventually responds, maybe they can retrofit a new metal sleeve. I think that's the best outcome if not, as Dave Kirk recommends, sell the frame.
