>I am really liking the Specialized Command Post adjustable seatpost, which uses a mechanical system with an adjustable air spring, and has three locking positions, and a simple one bolt saddle clamp that is easily to install and tune the saddle’s position. Continue reading →
Strengths: When it works, it's works in a very effective and predictable way
Weaknesses: not reliable enough.
First the good. When it has worked it has behaved perfectly. I never had any problem with it leaking air. It looks good.
Just before the 1 year warranty ran out I had a problem where the seat would rotate. They ended up sending it back to specialized and I got a brand new post. After about 2 years with the new post working , with me riding 1-2 times a week the post failed again. This time a bunch of the pawls on the collate that hold the post in place broke off. I saw someones posting on the command post thread that had this same problem and Specialized ended up replacing most of his post for a bit over $100.
I don't want to be spending money on an expensive seat post every couple of years. Instead of dumping another $100 into fixing this post I decided to abandon it , and instead go for a Gravity Dropper turbo Multi LP. From what I can tell from the reviews, it's not quite as sexy as the other dropper post options, but it seems like it works well and is reliable.
Weaknesses: single bolt design on seat clamp makes saddle more prone to slipping which happens all the time.
ergonomics - actuating lever is terrible - either put in position that interferes with shifters or put in position that requires massive wrist contortion
three positions: how can specialized offer only three positions when the competition offers infinite adjustment
quality: went through two.
I have ridden a Reverb, KS Lev, and Command Post. The command post can't hold a candle to the other two. The seat post clamping design is terrible. Unlike its competitors which use a more secure two bolt design, the one bolt design of the CP makes saddle a slippage a sure thing. This is inexcusable. Ergonomically, I challenge anyone to show me a position that is both comfortable and does not interfere with trigger shifters. In order to not interfere with shifters the trigger for the seatpost had to be rotated so far forward that the only way I could actuate it was to look at my handlebar - this is not what you want to be doing when you actually need to drop a post.
I could go on and on. I am no Specialized hater, I loved there Stumpy 29er EVO. They just should stick to frames and tires. This seatpost is the single worst piece of Spesh gear ever designed and needs to be pulled from the market because it just plain does not function in the way a rider needs it to.
Strengths: Simple to setup, minimal to zero rotational play, smooth operation, smart looks. Lever is more robust than some 9when flipping the bike)
Weaknesses: "Spare" cable is annoying (would love a stealth version), lever requires quite a lot of effort. A little heavy.
Used for about 18 months. Overall a reliable, solid and good performer. Needs occasional clean/lube to keep it from slowing/missing the detents but none of that requires diss-assembly (so far). Personally I like the 3 positions over infinite adjustment as its more consistent.
I'm totally sold on dropper posts now - just wish they would make this with a fixed cable length like the KS post - and a bit lighter would be nice1
I use a Gravity Dropper Turbo that I'm extremely happy with. I used this seatpost (Specialized Command) on a rental for one day. The GDT is significantly better. The GDT 'finds' its position more definitively. The GDT's lever is more definitive, as well. The lever doesn't look as cool or as sophisticated as the Command's, but it just works better. GDT's lever seems to grip the handlebar better, as well - the Command's lever moved/rotated on me a couple times. After one particularly hard bottom-out, with the seatpost all the way down, the saddle moved positions. The Command may have an advantage on how the cable attaches to the post - the cable attaches up high and out of the way while the GDT's cable comes out of the post and could get snagged on something - I've never had a problem with my GDT's cable, though.
Weaknesses: Excessive play in the saddle. Saddle does not stay in position and slides back and up on every ride. Control lever broke. Seatpost also finally broke, prompting me to post this review.
Riden for five months and this seatpost is truly awful. Been nothing but problems. Control lever broke on my third ride - fixed with a zap strap. The saddle constantly shifts back (!!!) and up. The post no longer goes up and must be adjusted manually. The bike shop told me I was too large (235 lbs, 6'4") for this seatpost, and failed to offer any support (or the recommended rider weight). The engineering design on this post is very poor. Might be fine if you are a flyweight - but stay away if you are big, and do backcountry riding where reliability is important.
Strengths: Reliable, smooth action, easy to set up
Weaknesses: Ring that holds the seal on comes loose and leaks air sometimes. You have to replace the cable every few months.
I have had this post for almost a year now and have had no problems aside from the seal coming loose a few times and a couple worn out cables. For the money, it's great, and I would highly recommend it! Having a dropper post puts your bike into a whole new realm of versatility.
Weaknesses: The ring will become loose and looses air
I really like this seat post. It has been super reliable and the few times I have worked on it has been easy. After a few months of hard riding, I noticed sometimes it looses air. It takes two minutes to fix, so not a big deal.

Strengths: 3 positions
Weaknesses: Side to side play out of the box!
My first Specialized Command Post Blacklite was replaced by Specialized UK for excessive play, it’s failed after just 5 rides, my replacement Blacklite did not return to the power position out of the box, so I cycled it 20 – 30 to free it up and it instantly had side to side play. Three Specialized representatives have advised some play to be expected and that it will get worse as the unit wears, but none of them would give me an engineering answer to acceptable design tolerances.

Strengths: So far the Blacklight has been smooth and reliable. The black stanchion and red anodized parts add some flare to a pretty simple piece of equipment. Also, the handlebar mounted lever seems strong and sturdy, and can be mounted on either the right or left side of your cockpit.
Weaknesses: So far the only thing that I've experienced is that the bar mounted lever can be hard to push at times. I've gotten used to it, and I'm sure that some cable adjustment as well as some lube in the cable housing could remedy the problem.
For the time I've had it, the Blacklight has been a game changer. Before installing it, I had considered selling the bike. Saddle height plays such a major role in pedal efficiency that if it is compromised in only the slightest way, it can make your bike feel sluggish and "mushy". I had thought I could compromise by setting my standard seat post and saddle in and "in-between, not too high, not too low" position...the GOLDILOCKS position if you will... By allowing the saddle to be at the correct height for any and all situations you'll encounter on the trail, you are truly getting the most from your bike. The Blacklight Command Post saved my bike's life!
As far as reliability, only time will tell. I have, however, been running the original Specialized Command Post on my 2011 Enduro, only having to replace the cable as it had grown worn-normal maintenance. With proper care and upkeep, I have no doubt that the Blacklight will be just fine. I will, though, update this review with any developments, both negative and positive.

Strengths: It looks good.
Weaknesses: This Shock does not perform as it should. It sticks and does not hit the height adjustments. On ride number 10 the shock completley stuck in the down position and I had to take it back to the dealer to have them send it out.
Not a reliable shock. I expierienced problems after 3 rides. Turnaround time to repair or fix is two weeks out.

Strengths: Three fixed positions
When operable, the Command Post is fun, but not $300 worth of fun. While I've enjoyed being able to drop my seat on the fly to take on a steep downhill, the problems I have had with my command post (inoperable once, no rebound another time, seat clamp allows the seat to tilt easliy)have eclipsed the fun.

Strengths: Best of both worlds. Seat is at correct height for efficient pedaling, but can be lowered to tackle technical sections without disrupting flow of the ride.
Weaknesses: Cable attaches to a small anchor bolt.
Purchased one of the early versions of the seat post back in 2009 that leaked air. Sent it back to Specialized and they fixed it by putting in some upgraded seals/parts. After about another year the seat would not stay locked up. LBS sent it back to Specialized and they sent me a new replacement. Thumbs up to my LBS Dukes & Specialized!
Great product and it is worth the ~0.5 lb weight penalty over a conventional seat post. Mostly use the middle position but sometimes drop it down all the way if riding something technical where I may have to bail out and not worry about getting caught on my seatpost.
The product can be improved if the anchor bolt holding the cable was larger to allow for more clamping area. Also it cannot be replaced with a standard shifter cable. I believe that Specialized may have started using a standard shifter cable in the more recent versions of the Command Post.
There is a tiny bit of lateral play in the seatpost but it does not bother me.

Strengths: It straight up works! Nice to have the schrader to adjust return pressure.
Weaknesses: Flimsy handlebar lever. Easy to replace tho, had an old rockshox lockout lever that works just fine.
For a no-worry, set-it-up and ride product, the command post is it! Riding a joplin was an effort in extreme paranoia: When is it going to give out? You never notice the CP. In 1 year of all-mountain riding in the best chunk New Mexico, Arizona, Colorado and Utah have to offer, the CP has had no issues apart from a broken engagement lever, which can happen to any part if its hit just right. An adjustable height post is worth dealing with some issues, but the CP doesn't have any significant ones. Get it and ride!

Strengths: Simple, durable, reliable.
Weaknesses: Not as many options as the newer models (i.e. even the 2011 Specialized Command Post).
This post works and has been very dependable and reliable. It worked pretty flawlessly / reliably for over a year until it started getting less reliable. Finally took it in and had it serviced, wound up getting it rebuilt by Specialized. Just got it back and installed it myself and it works better than I remember it when it was new. Very happy with the post and with Specialized--great products, great customer service. My bike and other Specialized products have worked very well and have been very reliable.

Strengths: Great for long downhill sections and hard hitting drops. The drop mech has worked great and smoothly every time.
Weaknesses: Seat clamp does not keep the seat in place when going over small steep bump/ditches while on the saddle. First the post squeaks in protest of you not getting out of the saddle, it then allows the nose angle to point up (with painful results)
specialized's single bolt seat clamp design is a looser. I have never had a problem with any other type of seat post letting the saddle move all over the place. I made sure that the proper bolt torque was used as well as aligning the arrows. The whole point of the rear brain suspension setup on this bike is to peddle while on the saddle and hitting bumps. Also if the seat could drop out of the way as quickly as it returns to full height would be a welcomed improvement.
