Clamping on dropper post

hold on...when you sit on the saddle how much angular force goes through that seatpost and seals...especially going over obstacles?

So I get that, but sitting on the post and pulling on the post are two very different things.

I would take a leaf out of Droo's book and pull it out to clamp on the non stanchion bit. 

Not because I think it will destroy my dropper but mostly because it is definitely not going to destrot anything

Some science and whatnots in there.

I agree with this, but sometimes the cable is not long enough to pull the dropper up higher or the seatpost clamp bolt is damaged (more common than you may think). So in an ideal world, this is what I would do, however sometimes time is of the essence and you need to get something done fast.

nope.

The seattube insert component is thinner walled than the stanchion component and it's already deformed by the seat post clamp which is holding the weight of the bike and taking the bending moment set up by the weight acting the CoG of the bike and bending the inserted bit. By sliding the post up to expose more seat post there's more moment on the clamp and inside wall of the frame. Don't worry the frame can handle it but  dropper post body now will have an additional compressive strain from the clamp which will be acting on the internal bits that work on that bore. I'd much rather just clamp the stanchion as its the thickest walled and strongest component because its designed to handle a higher strain, Its also hard anodised to cope with lifes little scratches from stones being shot at it from tyres. 

Simple rule of thumb: clamp the strongest component
