Free to a good home. This is a 31.6mm dropper post that like many of these dropper posts, needs to be bled about twice a year. I'm not sure of the extension but I think it is probably 150mm because it seems like it went up pretty far. I used it on my Trek Fuel EX7 MTB.
My bleeder syringe broke and so I bought a brand new dropper post.
I might be missing one of the bolts that holds the seat bracket on too. I'll try to find it.
I have a half a bottle of extra fluid and one of the syringes, as well as the proper fittings.
I was going to throw it away but you might as well take it off my hands for free.
