+1 I'd have to be surprised if carbon tubing is really too fragile to clamp in a bike stand that is made to service bikes. Wouldn't Park Tool for example be the first to have disclaimers? OTOH most ParkTool videos always show the seatpost being clamped. Are seatposts generally considered stronger tubing than the frames?
I've never thought about this much before. I've always clamped on the seat tube, and my bikes are Ti with CF seatpost, and Steel with alloy seatpost.
This attached snapshot from the PCS10 PT video makes me cringe a bit.. Maybe it's just me, but I'd would never consider clamping on the seatpost if working on a bike clamped at this angle.
