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
proficiency and/or ability to install this product. Specialized recommends that the
Command Post be installed by a qualified 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, flat 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 fit and/or torque issues, it is recommended that
the fit tolerance be verified by a Specialized Authorized Dealer.
INSTALLING THE COMMAND POST
On non-carbon frames only
1.
, grease the seat tube I.D. and Command Post O.D. (see fig.
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 fig. 2).
4.
IMPORTANT! Recommended torques in this manual are specific 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 fixed 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 specific
frame and seat clamp used. Exceeding the max specified torque limit (see fig. 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 fig. 3).

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 fig. 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

hex key (see fig. 4).
Insert the cable through the slot on the remote lever. Pull through until the cable head

rests in the slot (see fig. 5).
Insert the cable into the 90-degree pipe, making sure to insert the cable through the
