2019 Command Post IRcc

I really hope Specialized can chime in and help me out here. I ride a S Works Enduro and this post came installed from the factory. It's great, super fast and super adjustable. If I could find an exploded diagram with every single bolt and size of bolt that would be super helpful. However the small bolt that connects the pivot point of head of the seat guts with the post went missing during a ride, so my seat was flopping. This doesn't seem like hardware provided in any service kits(I checked), and since I don't have another bolt to compare it with, I'm kinda in the dark. Would be nice if I could find the specs of it to replace it with a hardware store piece. If anyone else had this issue and found the correct size, please let me know!

I open it up and lube it every few months and that’s all. Works like the day I got it. The key is to NOT over pressurize it. Manual says 20 psi max! I am usually between 10 and 15.

The post comes up and down most of the time. But coming up it can be so hard that it smashes your nuts. Going down can be rather unsmooth. Wort thing is the wobble that is constant and makes a terrible noise as if the bike is going to fall appart soon. Dosn't live up to the standart of my 2018 Enduro.

I had the previous version on my 2014 Stumpy and now have the new version on my 2018 Stumpy. This is a purely mechanical riser post that can be easily maintained by the owner. But, you will need to maintain it. The air leaks out of this past the seal on the post. It unthreads with the use of a strap wrench. There is a large O-ring just below the dust seal that seals on the post that slides up and down. There is another O-ring that seals between the threaded cap and top of the seat post that is clamped into the bike. The large O-ring is where the air starts to escape after the grease gets dirt in it and some of it moves past the dust seal. It is a 10 minute job to unthread the top cap, clean all of the parts, re-grease, and install. I use Slick Honey and I load up the inside of the top cap, including the small recess just inside of the dust seal lip. This lasts about two to three months before it starts to lose air again. So, why have this riser post? First, it is not hydraulic like the Rockshock posts. I have serviced several of those and they are a mechanical nightmare to get right. Even then, they develop that slight compression at the top very quickly. Second, it can be serviced by the owner. The air spring riser posts that use a sealed air cartridge are almost disposable. Once they go bad, you might as well toss it and buy another. So, is it the best? Probably not. But, it is easy to work on, reliable when maintained properly, never sags out at the top, and does not require bleeding.

After 6 months it started not smoothly sliding up and down.. I would not recommend this to anyone...

This is on my 2017 stumpjumper and is the worst dropper post ever! I've sent it to specialized twice already to fix it and it hasn't survived more then 2 rides

Specialized should be ashamed of this product - truly terrible. Expensive and unreliable. Avoid !!

I fires up like a canon firstly and it lasted about 7 months before not extending to full length.

I have run this post in my Enduro since 2016 and it has seen a couple of big impacts that bent my saddle but did not damage the post. The only thing that is a problem is dust - after a bunch of dusty riding it will get sticky and I need to strip & re-grease it. Fork Juice will help in the short term though. Luckily it is very easy to strip and rebuild. Please make it more dust tolerant though, this can be a pain. I like that it has defined engagement points and when it's locked in there is no movement unlike a Reverb. I also like that it returns very quickly. I've heard a lot of complaints about a lot of other dropper posts, but this one has been close to flawless for me.

There are two things I know of that can cause it to not fully return or to slip: 1. Cable is too short or set up poorly, which causes the locking mechanism to be partly disengaged and the seat will drop seemingly randomly. 2. Dusty seals or other lubrication issues will cause it not to return fully and therefore not engage in the uppermost lock position, therefore permitting it to slide back down again. If this happens when you buy it new or after a service you should take it back for a fix under warranty. Otherwise, get it serviced.

Every ride I need it to push 70-80psi pressure of air to make it work properly, At 40 psi the post just go up at the middle way! I would like to order the pieces of equipements to repair but difficult to find the wright manual on the website.

Firstly, the wires needed replaced within a year of riding which seemed like a cure all... and it still wont hold air for more than a ride. So lame! This dropper has so many issues.

I have had this dropper post on my Specialized Stumpjumper 6Fattie FSR comp (which I love, by the way!) and put about 1,200 miles on it so far. For the first two years, it worked great. After that, it started to leak air (which I have heard has happened to many others in bike forums). I now need to refill the air every 3-5 rides, otherwise, I have to pull the lever and manually pull up my seat when I need to go uphill. Bike shops won't even waste time trying to fix it because they say it was so poorly manufactured that it would be most cost effective to just buy a new post.

Would delete my previous review if I knew how.
