Bunker Remote 

Featuring a three axis adjustment, the Bunker Remote uses IGUS bushing, which is waterproof and much lighter overall. Also utilizes a small crank with less strength that allows for a light action and a longer lever. For other dropper post brands please confirm that the wire pull distance does not exceed 6mm.
