Specialized Command Post Adjustable Height Seat Post User manual

INSTALLATION GUIDE
COMMAND POST ADJUSTABLE HEIGHT SEAT POST
INTRODUCTION
The Command Post seat post provides riders with a way to adjust their saddle height
without tools. Although created by the Specialized Suspension team, the Command Post is
NOT a suspension seat post.
Visit a Specialized authorized dealer if you have any doubt regarding your mechanical
prociency and/or ability to install this product. Specialized recommends that the
Command Post be installed by a qualied bicycle mechanic.
Please read and understand all the warnings. Failure to follow a warning may result in a
catastrophic failure of the Command Post, resulting in serious personal injury or death.
This phrase may not be repeated in connection with each and every warning.
TERMINOLOGY
Power position:  When the Command Post is at full height. Used when full power
is needed, such as climbing a long, steep hill or riding a smooth, at section. This
position provides the full 100mm of available seat post height.
Cruiser position:  When the Command Post is in the middle position. Used for
pedaling on undulating terrain. This position is 35mm below the Power position.
Descender position:  When the Command Post is at its lowest position. Used for
riding downhill/freeride terrain. This position is 100mm below the Power position.
Remote Lever:  Used to actuate the Command Post.
INSTALLATION
Take the following items into consideration before installing and using the Command Post.
The air pressure in the Command Post is factory set to 25 psi. Air pressure 
determines the speed at which the Command Post rises. See SETUP AND USE for
more information.
The Command Post is 30.9mm in diameter. Prior to installation, ensure that this
diameter conforms to the diameter of the seat tube.
WARNING! Incorrect sizing interface can result in Command Post slippage or
failure, causing serious personal injury or death.
The Command Post should not have any play inside the frame. 
The Command Post should slide into the seat tube in a straight, smooth fashion. 
The seat collar should be positioned so that the slot faces forward to minimize dirt 
contamination from the rear wheel.
If the Command Post exhibits any t and/or torque issues, it is recommended that 
the t tolerance be veried by a Specialized Authorized Dealer.
INSTALLING THE COMMAND POST
On non-carbon frames only1. , grease the seat tube I.D. and Command Post O.D. (see g.
2).
Slide the Command Post into the seat tube.2.
Adjust the Command Post to approximate height for proper leg extension. The 3.
Command Post ships in the Power (full height) position. While in the Power position,
determine saddle height like you would a standard seat post.
Leave the Command Post in the Power position during installation. This will
ensure that the cable housing is at the correct length.
Adjust seat collar torque to recommended setting (see g. 2).4.
IMPORTANT! Recommended torques in this manual are specic for the Command
Post. Consult the bicycle owner’s manual for recommended torque. Always use
lower torque recommendation.
WARNING! Only use seat collars approved by Specialized with the Command
Post. Use of an unapproved seat collar may result in slippage and potential
damage of the Command Post.
The following 30.9 collars have been tested and recommended:
Specialized xed and Q/R collars 
Salsa Flip-Lock Q/Rs 
Please visit www.specialized.com for future approved collars.
NOTE: Do not overtighten. Use only hand pressure on Q/R lever. Only use enough tension
to keep the post from slipping. If you are having slipping issues, friction compound pastes or
talc powder can be used on aluminum and carbon frames.
WARNING! Seat collar torque requirements can vary depending on the specic
frame and seat clamp used. Exceeding the max specied torque limit (see g. 2)
can result in damage to the Command Post and/or frame. Consult an authorized
dealer for additional information.

INSTALLING THE REMOTE LEVER
The remote lever is connected by cable to the Command Post. A left-handed remote lever
ships with the Command Post; however, the remote lever can be positioned on either side
of the handlebar, if desired.
NOTE: If saddle is already installed, rotate the saddle out of the way, leaving the saddle head
lever exposed.
To install the remote lever:
Determine which side the remote lever will be installed on (see g. 3). 1.

NOTE: Do NOT apply grease if the remote lever is to be installed on carbon handlebars.
Clamp the remote lever on the handlebar, ensuring that the remote lever is the handlebar 3.
device closest to the stem (see g. 3). Before installing and tightening the hex screw,
operate the remote lever to ensure it doesn’t impede on other devices already on the
handlebar, such as shifters and brake levers.
Screw the hex on the clamp and torque to 15 in/lbs. using a torque wrench and a 4mm 4.
hex key (see g. 4).
Insert the cable through the slot on the remote lever. Pull through until the cable head 5.
rests in the slot (see g. 5).
Insert the cable into the 90-degree pipe, making sure to insert the cable through the 6.

Press the remote lever and make sure the end of the cable and cable tip do not interfere 12.
with any of the parts (see g. 6).
Grease the saddle clamp mechanism (see g. 1).13.
Install the saddle in the clamp mechanism. 14.
Adjust the saddle to the desired fore-aft position.15.
Torque saddle head clamp assembly to 120 in-lbf (13.5 N-m) (see g. 1).16.
To avoid damage to the seat post/saddle assembly, align the arrows on the bolt
and the rail clamp (see g. 1).
Raise the saddle to the Power position, then readjust the Command Post to proper 17.
height, if necessary.
Verify cable housing length and check full range of Command Post travel. Make
sure the cable housing does not interfere with any bicycle components. In the
Power position the cable housing should enter the barrel adjust in a straight
trajectory, and the ferrule should have approximately 1mm of play between itself
and the barrel adjust (see g. 7).

IN THE POWER POSITION, THE CABLE HOUSING NEEDS TO ENTER THE BARREL ADJUST

1MM OF PLAY
Using the enclosed zip-ties, secure the cable housing along the length of the top tube, 18.
if possible. The cable housing should be oriented in smooth arcs as it leaves the remote
lever and as it approaches the saddle head, while maintaining the 1mm of play as it
enters the barrel adjust.

SETUP AND USE
The Command Post provides the rider with a simple and convenient way to change saddle
height without tools and, sometimes, without having to get off the bike.
Adjusting the Command Post position while riding may result in loss of control.
Check cable tension if the Command Post suddenly rises or lowers while riding. 
Ideally, there should be about 1mm of play between the cable ferrule and the barrel
adjust.
The remote lever is used to change the height of the Command Post: 
To move the saddle up, press the remote lever and guide the saddle upward to either the »
Cruiser or Power position.
To move the saddle down, slowly unweight the saddle, press the remote lever and guide »
the saddle to the Cruiser or Descender position.
The Command Post uses an air spring to propel the saddle upwards. The pressure in 
the Command Post is factory set to 25 psi (1.72 bar). Specialized recommends that
body weight be used to guide the saddle up or down.
Never exceed 35 psi (2.41 bar) in the Command Post air chamber.
MAINTENANCE
Routine maintenance of the Command Post will provide years of trouble-free performance.
Before every ride:  Clean the exposed portion of the Command Post shaft with a rag.
Every 3 months: Check air pressure, or sooner if you notice a signicant decrease
in saddle movement speed. Use a standard shock pump to check and increase/
decrease air pressure between the 20 to 30 psi (1.38 to 2.07 bar) range.
After 1 year or 150 hours:  Have your local Specialized authorized dealer inspect and,
if necessary, service the Command Post.
The air chamber must be fully discharged before performing any service.
Discharge the air chamber in the Power position.
ADDITIONAL WARNINGS
The Command Post is marked with a minimum insertion line. This is the minimum 
amount of insertion required for the Command Post to remain structurally safe.
However, some frames require additional insertion to ensure that the frame remains
structurally sound as well. The base of the Command Post should extend far enough
into the seat tube to extend below the underside of the top tube.
Specialized Authorized Dealers: Before conducting any service or inspection of the 
internal parts, make sure the Command Post is at full height (Power position) and
completely release all air pressure from the air chamber.
