[Closed] Working on a carbon MTB with dropper?

Has anyone (in U.K.) tried one of these for faff free clamping in a workstand?
Also anyone sourced one (or similar) in U.K.?

Just hate having to pull whole post out of the frame (reverb stealth) and the associated hose faff.

That seems a bit overkill? Can you pull out your dropper a bit and clamp around that?

I just clamp mine on the top tube with a cloth around it. Same way I clamp it to the bike rack and I haven't broken one yet. (Not there anyway...)

Just clamp the moving part of the dropper (taking care not to mark it by wrapping a cloth or something around it). If you let the seat tube hang vertically, by having the front wheel lower than the rear, there's little stress on it anyway.

Clamping the bottom part of a dropper is probably the very worst idea as it's only quite thin tubing.

Milkie, they're stealth posts so it's a faff on pull-pushing hoses through frame because they're all tightly grommeted.

That's what I have been doing, I'm just trying for a simpler option.

I've also tried the top tube clamping but I hate the fact that 30+ lb is hanging on it (my car rack has the wheels clamped in support rails so the weight is supported there)

Thanks for the input guys, I'm probs looking for the "moon on a stick" solution.

As above, wrap a soft cloth round the dropper stanchion.

Lower stand so wheel(s) touches the ground, less weight to support. However, what do you when lifting your bike? Same amount of weight and it doesn't bend so not really and issue. 30+lbs isn't much really.

I don't think the weight is the issue, it's the compression of the tube by the clamp - I have a clamp that won't rotate to the right angle for the seat post on my carbon road bike so I just clamp it up.

As long as you're gentle you should be fine, same as with lightweight metal frames. I wouldn't want to clamp on a dropper stanchion as even a small scratch could wreck it.

Been clamping on the stanchion (gently) for years with no problems. Small scratches don't wreck dropper stanchions anyway, just sand them smooth and they'll be fine, it's not like a fork, there's no oil in there and the air is inside the stanchion not the outer sleeve. They also move relatively few times a ride compared to a fork or shock. Sure, it's not ideal but it'll not wreck it.

Not while I'm looking please.

*shudders*

Can't you rotate the clamp and secure the nose of the saddle?
