Many thanks Anthony

    I clamp my Cube Reaction GTC Pro with the Thule rack - not dead yet. Due to the frame and rack layouts the clamp is right at the bottom of the downtube, close to the bottom bracket so a pretty sturdy place to be clamping. Besides, it's not a vice, it just needs to hold it snug.

    The carbon frame is likely to be much more robust than an aluminium frame with a higher force required to failure, don't hear of many issues with Al frames.

    I use mine with carbon frame but i wrap the downtube in some 3mm Correx first just to spread the load a little and protect the paint, as said above it doesn't have to be clamped super tight like a workstand would.

    The jaws just need to be snug enough to stop it moving around

    Brilliant thanks guys fears averted
  • Apply some helicopter tape where it is going to be clamped. I never bothered on my old bike and it eventually wore the paint off the frame.
