Ideal trail conditions.

In an ideal world, we wouldn't have to think about our seatpost height, and it would automatically adjust based on upcoming terrain. While we're still looking for that trail predicting technology to hit the market, you can keep your trail flow rolling with the FOX Racing Shox Transfer Factory Series Dropper Seatpost - Internal Routing. A smooth, eye-catching Kashima coated upper post and cable-actuated hydraulic internals pair for friction-free modulation with and an easy to engage action that deftly manges transitions across all manner of trail conditions.

The Transfer's internal cable routing keeps everything tucked neatly away in the frame for clean aesthetics, while a Spool Valve design utilizes beefy hydraulics for easy modulation so the post always ends up exactly where you need it. As an added bonus, a tool-free cable disconnect feature makes for easy installation and maintenance.

FOX Racing Shox offers two separately sold lever options for its Transfer dropper posts. The left side below bar mount sits similarly to a standard shift lever, adding clean symmetry to one-by systems. The left/right on bar mount sits how we most commonly think of dropper post levers, and provides clean integration with any shift system.

  • Transition seamlessly across varied terrain
  • Hydraulic internals for smooth, light actuation
  • Kashima coated upper post reduces friction
  • Internal routing for clean, cable-free frame lines

Awesome Dropper Seat Post

  • Familiarity: I've used it several times

I'm new to mountain biking and was told I must get a dropper for my bike. It was a great decision. The seat stays put and easily moves up and down when adjusted. Great buy.

Top Notch Dropper

  • Familiarity: I've put it through the wringer

Love the post but not sure Kashima is worth the extra cash unless you care that it might match your fork/shock.

Best dropper so far

  • Familiarity: I've put it through the wringer

I've used Thomson (really like it), Rock Shox (hate it), and Fox, and the Fox is hands down the best. You won't be disappointed!

Matchy Matchy

  • Familiarity: I've used it once or twice and have initial impressions

Looks great if you are wanting to bling out your rig to your fork. Post works well and has a nice audible thunk when reaching max extension and compression.

Drop it like it's hot.

  • Familiarity: I've used it several times

Looks great, not sure the coating adds any performance over the cheaper one. Has a bit of side to side rotation which seems to be common on most dropper post. I have never noticed the movement while riding. Has worked flawlessly ever time the lever has been pushed. The lever seems to be good quality as Well.

Good post for the most part

  • Familiarity: I've put it through the wringer

I bought this as an upgrade from my Lev integra 125mm, but after getting saddle mounted to this post the dropper shaft rotated side to side slightly. Not a big deal, you barely notice it while riding, but my integra had no play to it at all. Solid post other than that.

Up/down post

  • Familiarity: I've used it several times

The Transfer post does it's job. Smooth operation. Easy install and set up. It goes up, it goes down and makes riding in varied terrain a breeze.


    I bout this fox Seat dropper for my giant and it has made my riding experience 100 times more efficient and my rides are more enjoyable. no I can stay with my friends and never have to fiddle with the seat no matter what kind if riding I do!!

    Flawless season 1

    • Familiarity: I've put it through the wringer

    I have always loved using a dropper, but had experienced various issues with them on long and short rides that left me wanting to the point where I stopped using them. This one has been great, no issues thus far. Going into season 2. Looks very cool on the bike with the matching Kashima coated fork.

    Are there any performance and functional differences between the kashima and standard black model?

    The only difference is the Kashima coating (I asked a Fox employee at Interbike)

    Almost perfect

      I could not be happier with my choice to purchase the Fox Transfer internal routed 150mm drop post. It works perfectly.

      However after a handlebar to tree strike and subsequent fall I noticed that the clamp which holds the lever to the handlebar had broken. Once I saw that it had broken I noticed that the clamp seems to be very 'lightly' built. I know it probably saves a couple of grams but make it able to resist at least a few strikes. i've had the post for about two months and now I will have to buy a new lever as 'warranty will not cover impact or over torque'.

      Very happy with the post itself. Might look at another brand when buying the new lever.

      Almost perfect

      Buttery Smooth

      • Familiarity: I've used it several times

      Drop it like its hot. Fox has really done it this time. Very smooth action, slick styling, and super easy to install. Drops smoothly and effortlessly and returns quick. There is a little side to side play but this is common with all dropper post

      Dan is awesome. Highly recommended as I've built several bikes from. The best customer service hands down...honest and will take care of you. Thanks Dan! His extension is 4316.
