Specialized Command Post BlackLite Dropper Seatpost
|MSRP : $275.00|
Product DescriptionWe designed the Command Post BlackLite to have three consistent—and most importantly—repeatable saddle height positions. This is crucial for riders and racers who demand the ability to quickly toggle between optimum climbing and descending body positions.
The Command Post BlackLite (CP) is a mechanical 3-position locking height-adjustable seatpost, that comes in 75, 100 and 125mm ranges, and has a handlebar mounted remote, and single bolt keyed saddle clamp system. It’s available in 30.9mm and 31.6mm diameters, 75, 100 and 125mm travel options, and 330, 380 and 405mm lengths, respectively. The three height settings are the Power position or full extension, Cruiser, which is 35mm below Power, and the Descender, which is the lowest travel position, or 75, 100, 125mm below Power.

Weaknesses: leaky seals, horrible warranty
Date Reviewed: February 19, 2015
Strengths: This if for the 2014 Command Post IR (Internal Routing)
Simple to add air
Simple for maintenance- super simple to maintain and clean.
Fairly low lost
Can adjust speed return easily with air pressure
Weaknesses: #1 weakness is must push post ALL THE WAY DOWN in order for post to engage, else post will move up to 3/4" drop location. That is a pain. In a rush you just want to drop it quickly and may not push post all the way down and if you do that the post will not be in the low position. This is the biggest issue and i am surprised no one brings this up! If you pressurize beyond 25psi you will blow the seal and will have to get unit rebuilt!
Offset is not so big of an issue - we just push seat all the way forward in the rails.

Strengths: Worked for a little while.
Weaknesses: drop setttings not to my liking
As mentioned the seat clamp will roll if you land a little hard on the back end or nose.
I've taken it apart multiple times now to relube and change the cable. It is pressured up. It barely moves now unless I grab it with my hands. I can only assume it has a slight bend which is binding up the movement. 13 months of northeast riding (about 9 months of riding)...old guy - about 40-50 rides total....it's being replaced.

Weaknesses: None yet
I wadded up a brand new seat on a roughy landing. Bending the chromoly brackets on the seat and not affecting the post at all.
The ride heights were perfect easy transitions from all three stations. I got this for a steal as the LBS was transitioning away from Specialized. 30% off I'll take it!

Strengths: I like the three settings and posted has worked with no issues for the last two years
Weaknesses: The seat bolt clamp is crap; every time I go down hill and my ass hits the back of the seat it changes the tilt. I have a digital torque wrench and tried it at specified 120psi and seat became a suppository the first big bump. I then adjusted it to 140psi and it worked better only moving a little. At 155psi the bolt breaks so don't go there. Last resort I took my dremel and made deeper groves and added abrasion paste, that works best of all but still not perfect. (FYI: I ride XC and not DH this bike). Also the lever to actuate is difficult to use in cold weather and the prerouted bend does not fit well with my brakes and shifters

Strengths: Relatively high reliability, for a dropper. Easily maintainable. Internals tolerant of minor damage (see below).
Weaknesses: Setback seat clamp. Remove lever is crud, IMO. Single-bolt saddle rail clamping mechanism. Remote level paddle is hit-or-miss on who will like it. For me, it was simply huge and hard to get into a position where I could use it but it would not be in the way. Cold temperatures make the mechanism work very slowly, if at all, sometimes requiring manual assistance. I have now and then had the collar come loose - this is easy enough to screw back by-hand on the trail, but if you don't catch it then the post can bleed out the air spring. No damage from the post coming loose, just loss of psi.
I really have grown to like the fixed 'cruiser' position, having ridden with other infinite position posts I find this just works better for me. I tend to use that middle position for a lot of the technical trail riding as it is high enough to pedal without killing my knees for some distance but low enough to let me work the trail well with the bike.
The post has about 2500 miles on it in a bit over a year of use, varying conditions from summer to winter. It has functioned reliably throughout, even with a couple mechanical failures.
1st failure was that the remote lever exploded - after about 4 months of use. No crashes, but simply put the pivot wore out. I used a cotter-pin for a while through the lever but eventually replaced it with a Kind Shock remote which is still going strong.
2nd failure was found when doing a routine check of the internals, a couple of the 'leaf' pieces of the collet which locks it in place had broken off at some point. The post worked fine w/o all the leaves, however I sent it in to Specialized for rebuild. Since I wasn't their "original purchaser" it cost me a bit over 100$, including shipping.
The post has never left me "low and dry" on the trail - always able to be locked in any position even if all the air had bled out.
I have had the release mechanism "stick" when temps are low ... as in 14F ambient temp. I have not "winterized" the post yet though, that comes next.
I'd likely buy this post full-price as the only two on the market I'd consider that may be better would be the Kind Shock Lev or the Thomson dropper.
I find that I use the post a lot more than I originally thought I would.

Strengths: Price- over other options with these features.
Weaknesses: Seat clamp bolt had to be retightened. Not a real issue, but keep an eye on it. Also , for new users, it will hammer you in the pills if you're not expecting, or covering for it. Needs slight pressure to activate teh mechanism which I believe, is a good thing.

Strengths: 3 positions are great for me, cost
Weaknesses: After 4 months it would not hold air any longer. Took 6 weeks to get it back from shop with lots of excuses why Specialized took so long to get them the right parts. Had it back for 2 rides and it shot right out the top. Total failure! 3 more weeks later and still no seat post back in my hands.

Strengths: Works exactly as it should. Three settings is plenty. Responsive and raises/drops easily and immediately with a push of the button. Relatively lightweight and inexpensive.
Weaknesses: Seat clamp must be overtorqued to prevent fore-aft rotation of the seat when you land on it hard. That's the only thing preventing this dropper post from being perfect in my book.
I've tried an infitely adjustable hydraulic post, and although some of those are neat the three settings on this one make it something you don't have to think about during the ride, when you really shouldn't be thinking about it. As MTBR says, everyone should try this, even the weight weenies. They are perfect for those who just want to have fun.
The weight penalty is really quite modest -- only about 300g over a top end lightweight post like the Thomson Elite or various carbon posts. It would be nice to see weight-obsessed XC riders and racers try this and see if the increased versatility and ability to go downhill without being impaled on the seat is worth the small weight increase.
The only issue that prevents this model from being perfect to me is the seat clamp. I had some issues with it, not serious. The instructions advise you to grease the seat clamp upon installation, so I did. I also followed the Specialized torque specs in tightening the seat clamp. I am 225lbs with kit. A few rides later, I slammed down hard on the front of the saddle due to an unexpected bump and the saddle rotated downward with a loud "creak." On a later ride, it rotated backward with another creak when I went over a sudden drop and hit the saddle hard. This was easily fixed when I wiped off all grease and tightened the bolt to a greater torque, and since then it hasn't moved without my consent. (I assume this isn't compromising my seat rails, but I don't have much choice in using this post.) I like the simple design of the seat clamp but I should not have to over-torque the clamp. Specialized should reconsider the instructions, eliminate the advice to use grease, and consider adding a small tube of carbon friction paste or something similar to the package.
But that is really a small gripe about a terrific product, because it has worked for me just fine but for those two occasions. I would definitely buy it again over all the other dropper posts out there.

Strengths: Light weight, TIght (no wobbles). Hasslefree 3 height positions. Looks good. The simplicity of internal mechanisms makes servicing and maintenance simple. Adjustment for "trigger play" allows for a "safe zone" to prevent accidental activations.
Weaknesses: Speed of operation changes in mid use..causing the need to run higher pressures for faster return to extended position. Cable runs can be troublesome. My cable runs [to avoid interference with frame and cranks] have been down the downtube, and up the seattube, making for a very long run. Longer runs stiffen trigger operations. No option to retrofit a lever-operated trigger on the post itself.
