:shock: interesting tube being tapered like that if you look at the very top, you can see it is a llittle bit worn causing a taper.
can you try a narrower clamp or build up the top edge of the tube with laquer or epoxy. note with carbon fibre tubes, you need a wider clamp to spread the load - I'll measure up some of my clamps so you can see if you can go thinner.
