Fox D.O.S.S adjustable seatpost thread

[XgreygOOse]

Hi guys,
Thought I would start a thread on the new Fox DOSS seatpost.
I received mine a couple of weeks ago.

I got this to replace my old (1st Gen) Reverb post. I still like my Reverb post but I got tired of the amount of play on the Reverb post had. Got a warranty job twice on it and I think its still leaking oil from the bottom plus it still sticks a little when going up.......Anyway.......

The box. I bought a 30.9mm and 4" of travel.



I'll start with the weight. Mine came in at 614.5g. Box standard.


My old Reverb is lighter. 528.5g(30.9mm and 380mm) Of course its hydraulic so it should be.


Being a weight weeine at heart. I started to save some weight on were I could.
Changed the seat clamp bolts (They use the same 2pc bolts as Thomson does, just a little longer on the bolt).
Changed both steel bolts on the handlebar clamp to alloy ones. Used jagwire (more for looks, to match my frame) and I used Power Corz to replace the steel cable. Final weight 562g Not too bad.


A solid clamping system.




Three positions. Fox call it CTD (Climb,Trail,Decend)
I do like alot the fact it does have a set middle position. I use to always fiddle about trying to find a good middle position on the Reverb.

Fully extended


Midpoint drop (40mm)


And all the way down...


When I first saw the remote lever. It looked way too big and clumsy for me, coming from the reverb remote. Once I mounted on the handlebar, it start to make sense and the look grew on me. One of the things I loved about it was that you could mount it anywhere on the handlebar. Left,right, up, down and has a 3 position reach. It has two paddles. The inner one (black), when pressed it make the post drop 40mm only. The big silver paddle can also do this but if continued to be press it will drop down all the way. I can't see myself using the inner black paddle much as the outer paddle can function all the positions




The three reach position







And finally the speed in which it go's up. Fox says, to slow it down reduce the air press. Max. air presssure is 25psi. I have it around 18psi. As you see the video, I plan to reduces it even more.



The post does feel very smooth, solid, secure and zero play which was one of my pet hates with my old post.
I guess time will tell if Fox has a winner.

post a review after a few rides, i'm interrested in how it will be after a while.

Sweet review. Thanks a lot for the video and lots of pictures and unboxing.

I thought it won't be out till 2013? Where did you get it? I've been wanting to get one!

[James_spec]

Nvm, saw the price. I'll get one when im ready to trade in my left kidney.

In HK, the international distributor where given 40pcs. My LBS pick up 10 of them.
Agree, the price is abit high but after discount at my LBS it wasn't to bad. plus the LBS had a demo one and I got to play around with it. First impression was very good. Solid and zero movement around the post which my old one had alot of. I had to get one.
Retail is around HK$3500 which is about US$450. I pick mine up for around US$345.

I was going to say that from your username and what I can see of your build (Enve, Formula, XTR) you're probably not put off by the fairly ridiculous price that Fox is charging for their dropper post...

I'll be curious to see how the reviews shake out over the next few months. Thanks for posting.

I've been a little on the fence about my dropper posts as of late. I enjoy both my Reverbs but intend on trying a new LEV or Kronolog. There is however, nothing about the Fox post that makes me want to pick one up.

[dropadrop]

What are the official requirements for service intervals?

This, mostly, but am interested in the LEV only. I can't see how the DOSS gives any advantage FOR ME over the two very well functioning Reverbs in the house. The DOSS remote still looks cludgy, and the post end bits look nice and exposed with fidly little moving parts to get gunked up.

The LEV or the Reverb Stealth (supposedly coming soon for non-OEM sale...) are really the only two to offer any improvements over what else is out there.

Particularly the Reverb Stealth, assuming they really do have the kinks worked out. With its non-moving hose, not ripping the post end out gets rid of one of the issues some people have had anyhow.

The video makes it look like an ejector seat, ouch!

[dRjOn]

anyone know the overall length of the fox? 400mm? longer? cant seem to find that anywhere...cheers

[Surfas]

Will be possible use it with Joplin's remote lever???

[XgreygOOse]

The reason I will reduce to 10psi. The video was with only 20psi

What are the official requirements for service intervals?

Here you go.

[XgreygOOse]

Overall length is 335mm with a minimum insert on 95mm

[XgreygOOse]

I haven't used this post before so I won't know. The DOSS remote is very simple. Basically it pulls the cable, very much like a trigger shifter. The spring load is pretty small.

Should be renamed the Fox V.O.S.S .... Vasectomy On Steep Sh1t

[dRjOn]

sorry to be a pain: is that 335mm with 95mm in frame (so total would be 430mm similar to the reverb) or is the 335 a total length?

if its the latter its too short for my uses! :-)~ thanks!

Stay away from the Kronolog. I have personal experience with that item. If you choose to disregard, don't say you weren't warned.

The total allowed out the the frame would be 240mm (335mm minus 95mm)

[gticlay]

I'm super old and oldschool. And this was the first post I even thought about trying. But after seeing your video with the "ball killer" rise... I'm rethinking the whole post thing. OUCH. I'm sure I'd hit the thing and snag some ball!!

[dRjOn]

hey grey goose! thanks, if i understood the rep system thing id add one!....

335mm, though, that is short. does it come in different lengths do you know? id need 400mm

cheers!....

[fcaw11]

There's a 5" drop version.

[dRjOn]

an ebay seller suggests the length of a 5" version is 386mm....seems an odd choice?

[dRjOn]

just found this:
Universal Cycles -- Fox Racing DOSS Adjustable Seatpost
looks like 2 lengths for both drops - 335 or 386mm. nuts!

if 386 is from saddle rail middle to the bottom of the post, minus 95mm is going to leave me 10mm too short......which would be a shame.
