Description

Drop in.

Fox wasn't quick to jump into the mountain bike suspension market. But, because of its motor-sport suspension knowhow, when they did it made a huge impact to the market -- for the better. The same holds true for its introduction of the Doss Dropper Seatpost with Remote Lever.

One aspect that's detracted from the utility dropper posts is lateral and rotational slop. When riding aggressively, you need to know what the bike is doing, and one way the bike communicates to the ride is through the saddle. To ensure nothing's lost to poor tolerances, Fox uses a dual internal cam mechanism to solidly lock the post into position.

One cam controls the anti-rotation apparatus, and the other controls post height. One nice feature to this system is that it's self-adjusting. As you use any post, wear is inevitable -- and, tolerances will be compromised. The Doss, however, will remain as solid as it was the day you installed it.

The cams are actuated via a handlebar remote with three distinct settings, which coincide with Fox's new Climb, Trail, Descend (CTD) approach to suspension settings. The ergonomic, all alloy remote can be mounted left or right, and above or below the bar to suit compatibility with any cockpit setup. The lever's reach is also adjustable to fit different preferences and hand sizes.

Another unique, adjustable feature is tune-able speed return. By adjusting pressure in the Schrader valve located below the post, you can speed up or decrease the rate which the post returns to its full height. And, the system is failsafe -- the post will always operate if pressure is lost.

The post uses a traditional two-bolt clamp that's simple to dial in the correct saddle level and fore/aft position. The Fox Shox Doss Dropper Seatpost with Remote Lever has zero offset and comes in either 31.6 or 30.9mm diameters, and has a 4in or 5in drop option.

Mostly Good

Nice mate to Fox fork and frame shocks. Small amount of up/down play (2-3mm) when all the way up. Cable guide will rotate around to back of post which helps when locking in a bike stand. Recoil/return is powerful with the advised 25 psi. - make sure you're in the right spot or it will spank your junk. Seems un effected by cold in contrast to what I've seen from friends with other models.
I put the 4" unit on a 5" travel bike.

is this the newest one that comes with 3...

is this the newest one that comes with 3 settings up down and lowered but not all the way down

Best Answer Responded on

Yep, 3 position like the Fox Shocks basically. CTD
1. Fully Extended - Climb
2. Mid Drop - Trail - Depress Both Levers Together
3. Full Drop - Descend - Big Lever Only
I posted feedback about a slight amount of play in the post but finding that common in almost all makes after talking with many riders in an Enduro Event. This is a good seat post. Hope that helps.
Cheers!

Solid and Reliable.

I bought one for my All Mountain bike and love that it has the 3 settings. An infinite post would be too hard to use for how I use the dropper. I set it in the middle position for all my "normal" riding which includes climbs up to 15% grade give or take, then I can extend it the extra 40mm for the Really steep stuff, 20% grade and up. Then I drop it all the way down for the descent. You always have it right where you need it in an instant without having to reset it somewhere in between. It just is a much simpler design, and there is a certain genius to that simplicity. I would imagine it would be a big plus for a racing application. I liked mine so much I bought a second one for my Downhill bike. now I can pedal the flat with a lot more ease and still drop it completely out of the way for the gnarly stuff. The two stage lever makes finding the position you are looking for so easy you can do it at full speed and concentrate on the trail instead of the lever/seat height adjustments.

Reliable Dropper Post

  • Familiarity: I've used it several times

Great dropper post. Install is very easy. This post operates in 3 positions only: Climb - full extension, Trail - 40mm drop, Descend - 100 or 125mm drop. It is not infinitely adjustable like a full hydraulic. The cable lever actuation is smooth and the post drops with minimal effort and has a adjustable pressure setting for the air chamber for return speed. You can mount the lever under or over the bar on either side. If you're running a single front ring the lever works nicely under the bar on the left. Stout two bolt saddle clamp is nice.

Buy it!!

This has totally changed the way that I ride. It allows for so much more control on the steep downhills. I would definitely recommend this product.
