Command Post Adjustable Height Seatpost Instruction Guide

Congratulations! Command Post is among the finest products available in cycling. This instruction guide contains instructions and warnings, plus
torque specifications, to be used in conjunction with the owner’s manuals and instruction guides supplied with your bicycle. As a dedicated cyclist with
demonstrably superlative taste, get and use a torque wrench.
Failure to follow the warnings in this instruction guide may result in a catastrophic failure of Command Post, resulting in serious personal injury or
death. This phrase may not be repeated in connection with each and every warning.
Command Post seatpost provides riders with the ability to adjust their saddle height without tools, providing a fresh, new perspective on your favorite
trails, and giving you the confidence (and cockpit stance) to expertly navigate new ones.
Visit a Specialized Authorized Dealer if you have any doubt regarding your mechanical proficiency and ability to install this product. Specialized
recommends that Command Post be installed by a qualified bicycle mechanic.
„„ Do not exceed 45 psi (3.10 bar) in Command Post air chamber. Before mounting the saddle, operate Command Post and ensure extension velocity
is not excessive or else injury might occur while riding. This applies equally to boys and girls.
„„ Incorrect sizing interface can result in Command Post slippage or failure, causing serious personal injury or death.
„„ Only use seat collars approved by Specialized for use with Command Post. Use of an unapproved seat collar may result in slippage, and damage
the Command Post.
„„ Seat collar torque requirements can vary depending on the specific frame and seat collar used. Exceeding the maximum torque limit can result in
damage to Command Post and/or frame, which can result in a loss of control of the bicycle and possibly injury or death.
„„ Command Post is marked with a minimum insertion line. This is the minimum amount of insertion required for Command Post to remain structurally
safe. Some frames require additional insertion to ensure that the frame remains structurally sound as well. The base of Command Post should
extend far enough into the seat tube to extend below the underside of the top tube.
„„ Activating Command Post lever while riding may result in loss of control of the bicycle, resulting in serious personal injury or death. Before slaying
singletrack, practice using Command Post around the house, on grass, or in the parking lot. Master before using.
„„ Air chamber must be fully discharged before performing any service. Discharge the air chamber in the fully extended position, or you might end up
in a world of hurt.
„„ Recommended torques in this instruction guide are specific for Command Post. Consult your bicycle owner’s manual for recommended torque.
When mating parts, use lower torque recommendation.
„„ To avoid damage to the seatpost/saddle assembly, align the arrows on the bolt and the rail clamp (see Fig. 3).
„„ Verify the cable housing length and check the full range of Command Post travel. Make sure the cable housing does not interfere with any bicycle
components, clothing, etc.
1. Aluminum frames: Grease the seat tube I.D. (Inside Diameter) and Command Post O.D. (Outside Diameter).
Carbon frames: Use friction compound paste on the seat tube I.D. and Command Post O.D. in the event of slippage (see Fig. 4).
2. Use a shock pump and check the air pressure in Command Post. The air pressure is factory set to 25 psi. Air pressure determines the speed at
which Command Post extends. Never exceed 45 psi (3.10 bar).
3. Slide Command Post into the seat tube. It should slide into the seat tube in a straight and smooth manner, and there should not be any play. If you
experience any fit and/or torque issues with Command Post, have a Specialized Authorized Dealer verify fit tolerances.
NOTE: Ensure that the O.D. of Command Post matches the I.D. of your bicycle’s seat tube.
4. With Command Post fully extended, determine saddle height as you would a standard seatpost.
5. Tighten the seat collar. To minimize dirt contamination from the rear wheel, position the seat collar so that the slot faces forward.
The following collars have been tested, and are recommended:
„„ Specialized fixed and Q/R collars
„„ Salsa Flip-Lock Q/Rs
NOTE: Do not overtighten. Use only hand pressure on the Q/R lever. Use only enough tension to keep the post from slipping.

NOTE: The remote lever has the option of being integrated with the Specialized locking grip by replacing the locking clamp on the grip, or being
mounted separately with any grip, including the Specialized locking grip, by using the supplied shim (see Fig. 5).
1. If you are using a non-Specialized grip, use the supplied shim by inserting it inside the lever collar before sliding it onto the handlebars (see Fig. 5).
2. Loosen the 3mm hex and slide the grip/lever (or lever only) onto the handlebars. When using the remote lever without the Specialized grips, slide
on the remote, shifter, brake levers in the order preferred.
3. Torque the 3mm hex to 15 in-lbf (1.7 N*m) using a torque wrench.
4. Operate the remote lever to ensure it doesn’t interfere with other devices already on the handlebar, such as shifters and/or brake levers. Loosen the
3mm hex screw to relocate the lever, if necessary, then re-tighten.
5. Insert the cable (Fig. 1, item H) through the slot on the remote lever (Fig. 1, item A), then through the non-grommeted end of the noodle (Fig. 1, items
B & G). Pull through until the cable head rests in the slot (Fig. 1, items E or F).
NOTE: There are two different cable head configurations, depending on Command Post model. Ensure that the cable head matches the remote lever.
6. Run the cable through the non-ferrule end (Fig. 1, item C) of the cable housing (Fig. 1, item I). Pull the cable taut, making sure the cable housing slides
into the noodle (Fig. 1, item G), then run the cable (Fig. 2, item A) through the barrel adjust (Fig. 2, item B) on the saddle head. Pull the cable, then
guide the ferrule on the cable housing (Fig 2, item C) into the barrel adjust.
NOTE: Some Specialized bike models come equipped with cable mounts on the drive-side of the top tube. Also, some Specialized QR seat collars are
equipped with a cable guide slot on the inside of the QR lever.
7. Slide the cable between the lever and hex nut/washer, then pull the cable end (Fig. 2, item D) with needlenose pliers.
8. While keeping the cable taut, tighten the hex nut with a 3mm hex key wrench (see Fig. 2).
9. Cut off excess cable with cable cutters, leaving 1/2” minimum past the hex key/washer. Place a cable tip on the end of the cable.
10.Press the remote lever and make sure the end of the cable and cable tip do not interfere with any saddle/saddle head parts.
11. Grease the saddle clamp mechanism. Apply blue threadlock (Loctite 242) to the bolt (Fig. 3, item E).
12. Install and adjust the saddle according to rider preference (tilt, and fore and aft positions).
13. Torque the saddle head clamp assembly to 120 in-lbf (13.5 N*m) (see Fig. 3).
14. Secure the cable housing using the supplied zip-ties and/or clamp mounts on the drive-side of the top tube (available on some Specialized models).
The cable housing should flow 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 (see Fig. 6).

„„ The remote lever is used to activate Command Post:
»» To move the saddle up, press the remote lever and, while maintaining contact with the saddle, guide the saddle to the next higher position.
»» To move the saddle down, slightly unweight the saddle, press the remote lever, and guide the saddle down to a lower position.
„„ Specialized has a special tune for riders in colder climates (50°F/10°C and below), which involves using a lower viscosity lubricant. Visit a
Specialized Authorized Dealer for more information.
„„ Store and transport Command Post in the fully compressed position to prevent nicks and/or scratches to the inner tube, which can lead to air loss.
„„ Specialized recommends visiting a dealer if there is any damage to the inner tube surface. Damage might result in premature loss of air pressure.
„„ When adding air to Command Post, make sure it’s in the fully extended position.
„„ Before performing any service, release all air in Command Post while in the fully extended position.
Routine maintenance of Command Post maintains optimal peak performance:
„„ Before every ride: Clean the exposed portion of Command Post shaft with a rag. Check inner tube for scratches, nicks, etc. Make sure lever action
is smooth and cable is kink-free. Lubricate the inner tube (exposed, anodized portion of seatpost) if the Command Post has been idle for several
„„ Every 3 months: Use a standard shock pump to check and increase/decrease air pressure between the 20 to 45 psi (1.38 to 3.10 bar) range.
Lubricate the inner tube and cycle Command Post up and down a few times. Lubricate the actuating cable at both ends. Adjust the barrel as
necessary to compensate for cable stretch, maintaining 1mm of play at the barrel adjuster. If ridden in muddy/rainy conditions, lubricate the cable
and cable housing with a Teflon-based lubricant (e.g., Tri-Flow®).
„„ After 1 year or 150 hours: Have your local Specialized Authorized Dealer inspect and, if necessary, service Command Post. If you ride in extreme
conditions (dirt, mud, sand dunes, Morgan Hill, etc.), you might need to service your Command Post sooner. Replace cable and cable housing AND
then check functionality. If the Command Post becomes inoperable after cable/cable housing change, see an Specialized Authorized Dealer.
