2012 Fox Racing Shox DOSS dropper seatpostDOSS dropper post is finally really real. Almost.

This one’s a 95% ready prototype. They’re still working out the last 5%, including whether or not it’ll have a Kashima coated option.

Push both triggers and it lowers 40mm. Push both and it drops 125mm. Push it again to release. Technically, you can release it slightly to bring it back up to the half way position, but you’ve gotta have a pretty sensitive trigger finger or weight the seat a little. This one shoots up fairly quickly, but not the fastest return we’ve seen.

Internally, Fox’s Euro guy says how it works is a big, big secret but there are no plastic parts.  I grabbed the saddle and there was virtually no rotational play, which is pretty impressive. If they can keep it that way after a bit of use, it’ll be a real accomplishment.

More pics after the break…

The dual lever lets you push both for short travel or the longer outer lever for full travel.

Their display unit’s cable got pretty frayed but we still managed to make it work for a few photos:

Not shown, they also have a new base level (cheaper) Remote lockout lever for front or rear shocks/forks. Their larger, higher end unit has a slicker release mech, but this one will be cheaper and work with twist shifters like Rohloff and old Gripshift.


  1. I hope this things works. Please Fox dont sweat the weight as much as the durability. The Reverb I have been using is pretty poor. Creaky, sloppy, fragile……

  2. I have been beating the hell out of my specialized command post, and I weigh 185 lbs (which only seems like a lot when talking cycling) – – and it has developed no play in over a year of use (over 1,000 mtn miles on it).

    I haven’t ridden the new lighter model, but i hope it is as durable.

  3. seems like rotational play is an issue with all telescoping posts. Why are they still making them round? Even if they stuck with existing round tech for seals, why not make part of the post slide in grooves, or make it an I beam or something so it can’t twist?
    Just a thought. I’m not claiming to know better, but it seems like all dropper posts are battling twist, yet they all remain round… If its not round, it won’t twist.

  4. Gotta agree with @pedalhound – that remote looks like an April Fool’s day press release. What is Fox thinking? The stupid thing is bigger than the XTR brake lever.

  5. what´s that lever! plase Fox!!!! you has been doing good products for a while and now are placing a lever that looks like a spoon? come on who cares half travel, full travel or no travel? if someone doesn´t know how to adjust a saddle on the trail is because never need a adjustable seatpost, simple like that.

  6. Greg, I beams are strong from a construction point of view, as in buildings, but an I beam shape would likely twist more than a tube! An I beam is good at carrying loads, but not so good torsionally.

  7. I’d have to agree with the majority here on the lever. It is too much just for a dropper post. Why do we need TWO levers?? yes, I know what they are for, but I think that feature is unnecessary.. especially in the trade off for having to use that lever…

    ONe of the Booths at Inter had, i think, Carl Deckers Super D bike on display and it had a Fox Dropper Proto on there. I don’t know if the levers were still in development at the time, but the cable was run to the left XTR shifter (with the downshift lever cut off). Of course, the bike was running 1×10 so the left shifter was available.

    Seriously Fox… drop the two, long, fragile levers and just give us one push button actuation… Oh, and that Kashima like the Super D bike would be super candy..
