So yesterday we received our first Fox Doss dropper post.What a piece of work, you can tell they spent some time on this. And I  think they nailed it. this one has a 4 in drop. We installed this on a Niner RIP 9 and went for a ride.
  The action of the lever is spot on. it does take a few minutes to adj to the third leaver but it becomes second nature. The post does not rock from side to side like a lot of the others on the market.
  As always the fit and finnish from Fox is awesome and was super easy to set up, So if your looking for a dropper post look no further. they are a little more money than others in the market but worth every dime.
