Are there dropper posts thinner than 27.2mm??

[Mod-Master]

I’ve got a 26mm seatpost sized frame and was wondering wether there were any smaller sized dropper posts that exist? Or maybe I should modify a suspension post?

unfortunately not

What a shame..

could it be turned down on a lathe

Gravity Dropper did a 26.8mm.
Hard to find now though.
I reamed my 26.8mm seat tube to 27.2mm about ten years ago. Still going strong.

I need a 26.0mm so the wall of the dropper post will probably be non-existent if I turn it down that much. There is some weird seattube action going on on my Sbike (what I’m planning to fit a dropper to) so maybe with some trickery I can enlarged it?


See that strange taper at the top?

Indeed, not quite-rite TM.
Your tapered seat tube doesn't look like a great candidate for modification. Out of interest, what is the extèrnal diameter of the seat tube?

Personally, I would look to recreate something like this:

It would be more in keeping with the bike, and means you won't need frame mods.
