Can you still buy Gravity Dropper seatposts (27.2mm) they seem to have disappeared.

(looking for a cheap reliable 27.2mm dropper post).

You can get em direct from GD in the USA, the end price with duty is about the same as they where over here,
They post pretty quick as well, I ordered a longer multi drop shaft for mine and it was here in less than a week..

Also check the European sites I keep seeing them there
