CAUTION: The combination of the safety alert symbol and the word CAUTION indicates a potentially hazardous situation, which, if not avoided, may result in minor or
moderate injury, or is an alert against unsafe practices.
The word CAUTION used without the safety alert symbol indicates a situation which, if not avoided, could result in serious damage to the bicycle or the voiding of your warranty.
INFO: This symbol alerts the reader to information which is particularly important.
GREASE: This symbol means that high quality grease should be applied as illustrated.
CARBON FRICTION PASTE: This symbol means that carbon friction paste should be applied as illustrated to increase friction.
TORQUE: This symbol highlights the correct torque value for a specific bolt. In order to achieve the specified torque value, a quality torque wrench must be used.
TECH TIP: Tech Tips are useful tips and tricks regarding installation and use.
INTENDED USE
The Command Post 34.9 seatpost is a multi-position adjustable seatpost with 130mm or 160mm travel. This allows for on-the-fly adjustment to accommodate for different riding terrain and conditions. It
is intended and tested for All Mountain biking (Condition 4) only. For more information on intended use and structural weight limits, please refer to the Owner’s Manual.
WARNING! Adjusting the saddle height will affect the handling of your bicycle by altering the center of gravity, weight and balance. Doing this while riding may result in a loss
of control. You should become familiar with and practice riding with the seatpost in a controlled environment away from traffic before tackling more aggressive and difficult
terrain.
CAUTION: When adjusting the saddle height, always use your body weight to guide the saddle up and down, and release the lever before removing your body weight from
the saddle.
CAUTION: Verify the return speed of the seatpost and adjust the air pressure if necessary. Be careful when extending the seatpost, as it does decompress quickly. Do not
press the lever to decompress the seatpost while your head is near the seatpost.

WARNING! Correct tightening force on fasteners (nuts, bolts, screws) on your bicycle is important for your safety. If too little force is applied, the fastener may not hold
securely. If too much force is applied, the fastener can strip threads, stretch, deform or break. Either way, incorrect tightening force can result in component failure, which
can cause you to lose control and fall.
Where indicated, ensure that each bolt is torqued to specification. After your first ride, and consistently thereafter, recheck the tightness of each bolt to ensure secure
attachment of the components. The following is a summary of torque specifications in this manual:
WARNING! 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 the
seatpost and/or frame and also hamper return action, either of which can result in a loss of control of the bicycle.

GENERAL NOTES ABOUT MAINTENANCE
The Command Post 34.9 seatpost is a high performance component. All regular maintenance, troubleshooting, repair and parts replacement must be performed by an Authorized Specialized Retailer. For
general information regarding maintenance, please refer to the Owner’s Manual. In addition, routinely perform a Mechanical Safety Check before each ride, as described in the Owner’s Manual.
• The air chamber, accessed by removing the air valve cap at the top of the seatpost, must be fully discharged before performing any service.
• The upper tube’s smooth anodized finish is critical to the smooth function of the seatpost. Always store the seatpost in the DESCENDER position to prevent damage to the upper tube.
CAUTION: When placing the bike in a repair stand, clamp onto the lower tube of the seatpost, not the upper tube or the seal head.
• Lifespan and the type and frequency of maintenance depends on many factors, such as frequency and type of use, rider weight, riding conditions and/or impacts. Exposure to harsh elements, especially salty air
(such as riding near the ocean or in the winter), can result in galvanic corrosion of components such as bolts, which can accelerate wear and shorten the lifespan. Dirt can also accelerate wear of surfaces.
SERVICE INTERVALS
CAUTION: To ensure proper function of the seatpost and to maintain your warranty eligibility, follow the service schedule below. All internal service must be performed by
an Authorized Specialized Retailer or Specialized Service Center (except cleaning/greasing the hidden portion of the inner shaft, fig.1).
„„ Before every ride:
• Gently clean the exposed portion of the inner tube with a clean rag, then apply a thin coat of grease or lubricant to the inner tube. Avoid pushing contamination into the seal.
• Make sure the lever action is smooth and that the cable is kink-free.
• Make sure the seal head is tight. If it is loose, use a crow’s foot to tighten to 150 in-lbf / 17 Nm.
• Inspect the seatpost for any damage (including but not limited to scratches, nicks, sticking bushings, excess friction, loss of air, proper seatpost function, bent saddle rails) that might require warranty service.
„„ Every 3 months:
• Use a standard shock pump to check and increase/decrease air pressure to between 55 - 70 PSI / 3.8 - 4.8 Bar (recommended). Do not exceed 100 PSI / 6.9 Bar (maximum). It is ok to go lower than 55 PSI if a slower
post return is desired.
• Adjust the barrel adjuster as needed so that there is a small amount of slack in the cable (slightly tap the lever to feel the slack; there should be a small amount at the top of lever throw). If ridden in muddy/rainy
conditions, lubricate the cable and cable housing with a Teflon-based lubricant (e.g., Tri-Flow®).
• Fig.1: Remove the circlip from the underside of the seatpost, then slide the outer tube up to the saddle clamp to expose the inner shaft. Clean the base and shaft, then grease the shaft using Slick Honey or similar grease.

CLEAN
THE BASE
„„ Every 6 months:
• Have your Authorized Specialized Retailer inspect, adjust, clean and grease the seatpost according to Specialized recommendations. If you ride in extreme conditions (fine dust, mud, etc.), a full service involving
replacement of wear items may be required. Wear items include:
• Dirt wipers
• Seals
• Bushings
• Top-out o-rings
• Alignment keys
„„ After 1 year or 100 hours:
• Have your Authorized Specialized Retailer perform a full service of the seatpost.
• Replace the cable and housing, then check functionality.
A small amount of rotational movement in the seatpost is normal and will not cause long-term damage.
If there is excessive rotational play in the bushings or the seatpost is inoperable after a cable/housing change, see your Authorized Specialized Retailer.

TROUBLESHOOTING
ISSUE SYMPTOM
Action between positions is sticky / not getting
full travel to the Power position
Seatpost slips in the seat tube
Post does not move when the lever is activated
Post moves without activating the lever
Slow/No return action 2-3 days after setting the
air pressure
Post not extending upon first lever activation
after being left compressed for a period of time
POTENTIAL CAUSE
SOLUTION
Grease has migrated from the sliding surfaces /
general lack of grease / contamination
Unthread the seal head with a torque wrench and crow’s foot, clean and grease the
outside and inside surfaces of the inner tube. Removal of the seal head from the inner
tube should not be performed by the rider**. Applying lubricant to the surface of the
inner tube can sometimes temporarily resolve stickiness
Grease has migrated from the inner shaft /
general lack of grease / contamination
Remove the circlip at the base of the seatpost, then slide the outer tube up to the
saddle head assembly (see fig.1). Clean and grease the inner shaft*
Pressure bleeds through the seal over time
Increase air pressure to the desired setting if pressure is below 55 PSI / 3.8 BAR*
Riding in cold weather (below 32°F / 0°C)
Increase the air pressure in 10 PSI increments, without exceeding 100 PSI / 6.9 BAR*
Seat collar torque too high
Inspect the torque spec or QR lever load and adjust if necessary*
Not enough friction between the seatpost and
seat tube
Verify the torque applied to the seat collar bolt, make sure it is torqued to the
manufacturer’s specification, and does not exceed 90 in-lbf / 10.2 Nm. If necessary,
apply friction paste to the seatpost/seat tube interface***
Cable and housing friction
Inspect the cable ferrules at both ends of the housing to make sure they’re correctly
seated. If necessary, lubricate or replace the cable and cable housing*
Too little cable tension
Increase tension by turning the barrel adjuster counter-clockwise (see fig.2, item 2)*
Cable and housing friction
Inspect the cable ferrules at both ends of the housing to make sure they’re correctly
seated. If necessary, lubricate or replace the cable and cable housing*
Too much cable tension
Reduce tension by turning the barrel adjuster clockwise (see fig.2, item 2)*
Incorrect housing positioning / insufficient
housing length (due to raising the seatpost)
Slide the housing back and forth slightly to make sure it’s seated properly in both
ends. If the housing is too short for the housing to seat properly at both ends without
binding when the handlebar is rotated, the cable and housing will have to be replaced
with a longer housing and cable
Air leakage due to main seal damage
Replace or service the lower seal assembly**
Grease has migrated from the sliding surfaces /
general lack of grease / contamination
Unthread the seal head with a torque wrench and crow’s foot, clean and grease the
outside and inside surfaces of the inner tube. Removal of the seal head from the inner
tube should not be performed by the rider**. Applying lubricant to the surface of the
inner tube can sometimes temporarily resolve stickiness
Grease has migrated from the inner shaft /
general lack of grease / contamination
Remove the circlip at the base of the seatpost, then slide the outer tube up to the
saddle head assembly (see fig.1). Clean and grease the inner shaft*
* This service can be performed by the rider.
** CAUTION: To preserve your warranty, these services/procedures must be performed by an Authorized Specialized Retailer. Any damage incurred while personally servicing your
seatpost is not covered by our Limited Warranty.
*** If the seat collar is torqued to specification and the seatpost slips in the frame, this may be the result of a fit/compatibility issue. Please consult your Authorized Specialized Retailer for inspection.

„„ Fig.6: Insert the saddle rails between the upper and lower cradle.
„„ Fig.6: Adjust the saddle angle and fore-aft position as desired, then torque to 58 in-lbf / 6.5 Nm.
5
INSTALLING THE SEATPOST
„„ Ensure the seat collar is positioned so the slot faces forward (fig.7).
„„ Insert the seatpost into the seat tube.
The seatpost should slide into the seat tube smoothly and without twisting. There should not be any play between the seatpost and the seat tube. If you experience any fit
and/or torque problems, have the seatpost and frame inspected by your Authorized Specialized Retailer.
To prevent damage to the frame and/or seatpost, it is important to have a minimum amount of seatpost insertion in the seat tube. This minimum insertion must meet the following requirements:
• Specialized-branded frames: The seatpost must be inserted into the frame deep enough so the 100mm minimum insertion/maximum extension (min/max) mark on the seatpost is not visible.
• Non-Specialized-branded frames: Please consult your frame manufacturer for any additional information about required minimum seatpost insertion into the frame. If the seatpost and frame minimum insertion
requirements differ from each other, always use the longer minimum insertion requirement. For example, if the frame requires 120mm of insertion but the seatpost requires 100mm, then the seatpost must be
inserted 120mm.
WARNING! Your seatpost and frame BOTH require a minimum amount of seatpost insertion into the frame in order to maintain structural integrity. If your seatpost is not
inserted deep enough into the seat tube to meet BOTH requirements, it may result in damage to the frame and/or seatpost, which could cause you to lose control and fall.
WARNING! For general instructions regarding the installation of the seatpost, refer to the appropriate section in the Owner’s Manual. Riding with an improperly tightened
seatpost can allow the saddle to turn or move and cause you to lose control and fall.

„„ Fig.7: Make sure the seatpost is fully extended. Position the seatpost approximately to the desired height, then tighten the seat collar to the frame manufacturer’s specification.
WARNING! Seat collar torque requirements may vary depending on the frame. For Specialized frames, torque the seat collar to 55 in-lbf / 6.2 Nm. For non-Specialized-branded
frames, torque the seat collar to the frame manufacturer’s specification. Do not exceed 90 in-lbf / 10.2 Nm, because it can cause damage to the seatpost and/or frame.
„„ Fig.7: Adjust the saddle to the desired angle (A) and fore-aft (B) position for the extended Power setting, then torque the saddle rail clamp bolt to 58 in-lbf / 6.5 Nm.
„„ Fig.7: Once the saddle angle and fore-aft are in the desired position, adjust the height of the saddle (C) if necessary, then re-torque the seat collar.
„„ Fig.7: Mark the saddle height by applying a piece of tape to the seatpost (D), directly above the seat collar, or take note of the graduation line on the seatpost.
„„ Fig.8: Remove the seatpost and measure the distance (E) from the lower edge of the tape to the bottom of the seatpost cable housing assembly (Xmm).
When installed in a carbon frame, do not apply grease to the seat tube/seatpost interface, and make sure the surface area is clean before install. Grease will reduce the friction
that is critical to a proper clamping of the seatpost.
To increase friction, carbon assembly compound (or carbon paste) can be used between the seatpost and seat tube. Before your first ride, test the system to make sure the
seatpost does not slip down in the frame.

INSTALLING CABLE HOUSING
The following steps apply to most frames with internal routing (fig.10 is specific to Specialized frames with the SWAT door). Certain frame manufacturers have specific internal cable routing
steps to follow, and may have to route from the head tube to the seat tube. Please refer to your frame manufacturer for additional information.
