What's the shortest dropper post?

I think I'm having a brain problem, I can't find any way of searching for this that doesn't return lots of results for 90mm XC droppers, but that's not what I mean.

I've got a size L Mk3 Bronson with a Reverb seatpost that came with it, and all is pretty good. But, I have to have about an inch of the 'main' post above the seat tube because if I try to put it any lower, the actuation stops working. Sometimes on particularly steep stuff I think I would enjoy that extra inch of standover. Can I solve this problem somehow?

bikeyoke always used to have the lowest stack height. when i got mine, a 160mm drop fitted in the same space as a 125mm reverb.

a lot of new products on the market so things may have changed since then.

Assuming you mean the height for given drop, then I'm pretty sure the OneUp posts are the shortest. And if slightly to long the travel can be reduced in 10mm increments.

There was a table, think it was on alltricks website, but it's probably quite out of date now. at that point the KS i900 was the shortest I think. You'll probably just have a to look at the dims on the different seat posts to find out, Brand x ones have a diagram like this that show all the dims.

Or go for a non internally routed one.

Have a look at the 9point8 Fall Line dropper post I like my seat slammed and this
was the best solution I found.

thanks guys, that gives me lots to go on (including a few better search terms!)

OneUp have usually got smallest insertion depth of any dropper, that's been their big USP since the beginning.

As others say, bikeyoke revive or oneup dropper v2.1 will fit the bill for you, the benefit of the oneup is you can shorten the travel as well with the supplied pins, meaning if it's still a few mm too long, you can shorten the travel by 10mm to turn a 150 drop into a 140 drop.

Was OneUp when I looked into it.

Went through this on latest build, trying to squeeze in maximum drop with my short legs.

One-up, Bikeyoke, and the 2022 Fox transfer (note the drastically different head design) are the best options.

I went with the Fox.

Is the seat too low if you run the post fully slammed? Because if it's slammed, you probably don't have to torque up the seat clamp very much at all (mines probably at 3-4Nm), and that could solve the actuation problem, potentially

@legometeorology no I think it's fine fully slammed. Interesting... I'm away from the bike for a few days (my brain only decides to solve these problems with poor timing) but I will give that a go first.

Cool, def worth a try. It shouldn't need much torque to stop it twisting while riding, which is all you need if it's slammed

Bonus is that it could also save your seat/post in a crash, as it'll be more likely to move than brake (same reasoning as to why brake levers should never be torqued up too much)
