General
Thank you for equipping your bike with an Eightpins variable seatpost, a highstandardized, highly technical product for mountain bikes. There is a
variety of points to take into consideration assembling and using the seatpost. As a result of the integration of the seatpost, it is designed entirely dif-
ferent in comparison to other variable seatposts. The adjustment of the seat height as well as the adjustment of the travel of the seatpost is realized
with one single tube. The mechanics for this is directly connected with the frame via the Postpin axle that absorbs all axial forces. The lateral forces
are absorbed by the bushing tubes and thus by the frame. It is therefore crucial to mind the maximal extension as well as the minimum insert length.
Attention! If assembled or used in a wrong way, you may hurt yourself as well as damage the frame or the seatpost.
Make sure all adjustment elements are in place at all times and that the tension of the cable is adjusted correctly. In case you do not have the skills
to assemble the seatpost, please refer to your local bike dealer or the service center in your country.
Attention! Read the following assembly information and manual carefully and stepby-step and mount the Eightpins
seatpost only according to the instructions.
Warranty Policy
Weoeratwo-yearswarrantyforyourseatpostbeginningatthedateofpurchase.Thewarrantyexclusivelyincludestherepairorexchangeofthe
components damaged. In order to claim a warranty case, the receipt is obligatory. Common wear, usual services and wrong assemblies are not
covered by the warranty. If the seatpost has been altered in any way, the warranty automatically expires. The rider is responsible for any damages
caused by any alteration of the seatpost.
Service
As to the service, a major advantage of the Eightpins variable seatpost is that the seatpost can be dismounted easily and that the anti-friction
bushing can be cleaned and/or exchanged quickly. In case you notice a higher friction in the system, it can be greased via a grease port in the outer
sleeve. With the right tools and a basic technical understanding, you may service the seatpost yourself including cleaning, exchanging or greasing
the bushings and exchanging the cable. If the hydraulic gas spring of the seat post gives way or fails, it must be replaced.

Safety instructions
Assembly and service
The assembly and the service of the Eightpins variable seatpost requires a special understanding of technical matters. Do not overestimate your
own skills but refer to a professional bicycle shop or to an authorized Eightpins service partner at all times. This is the only way a correct service can
be guaranteed.
Modications
The Eightpins variable seatpost is not to be altered in any way. Do not dismount it, sand it down or paint it. Always use a torque wrench where
necessary. Read the manual carefully and follow it step-by-step.
Attention: A seatpost that has not been mounted correctly does not work correctly.This may lead to crashes and
injuries. Besides, the frame can be damaged.
Use and area of application

The bushing tube length is selected so that it corresponds to the minimum insertion depth of the seattube in the frame. All
bending forces are transferred to the frame via the bushing tube. When assembling or exchanging the bushing tube, the
correct length must be used. The respective length can be found in the table under the column bushing tube.
It is also important to pay attention to the compatibility of the seatpost tube lengths. The table contains all possible combi-
nations. The corresponding adjustment ranges can also be found in the table. The values refer to the distance between the
bottom bracket and the upper edge of the saddle. Included is a saddle with a height of 4cm.
ATTENTION! Only the intended and compatible seat post sizes, strokes and bushing tube
lengths specied by the bike manufacturer may be used.

Installation
Frame/Seattube
Cable housing / bowden insallation
Install the cable housing in the frame before installing the seat post. Please follow the instructions of the frame manufacturer. The cable housing is
to be inserted into the seat tube until about 2 cm of it reach out of it. The second end of the housing – at the top of the frame – is to be cut depen-
ding on the frame size. The cable housing is pushed further out of the frame during assembly of the seat post by the length X. Observe the following
table when cutting the cable housing and shorten it to the desired length.

installed between the outer shell and the special end cap.
Hook the cable head into the
actuation lever of the seat post
Insert the cable into the outer shell and push it almost
completely through the cable housing
Before installing the seat post, check whether the small tube and the washers for tole-
rance compensation of the seat post are installed.

EIGHTPINS
Hang the special end cap in the cable housing holder of the seat post mounting inter-
face.
Attention! When installing in an aluminum frame with non-anodized
inner walls, lubricate the bushing tube with grease beforehand.
When installing in a carbon frame, never treat parts with rubbing
paste
Now carefully insert the seat post into the frame until the bushing tube slides into the
seat tube. Carefully press the outer sleeve onto the seat tube by hand until you feel the
outer sleeve stop.
Push the seat post down until the post pin mounting
interface of the seat post reaches the Pospin interface of
the frame. You can see this from the outside when you
look into the hole in the postpin interface of the frame. If
necessary, turn the seat post a little and slide it so that the
postpin axle can be inserted. Screw in the Postpin axle with
a 5mm Allen key and tighten it loosely
Push the outer sleeve and the bushing tube down for easier assembly. The cable must
remain tensioned throughout the insertion of the seat post into the seat tube of the fra-
me. It is best to hold the cable together with the cable housing at its end. Pull the cable
and the cable housing slightly during insertion so that it can slide through the frame.

Adjustment of the saddle angle
Before the Postpin axle is
tightened, the saddle must
be installed to align the seat
post.
Loosen both seat clamp
screws and unhook the
front seat clamp screw to
the front. Lift the upper
saddle clamp and position it
above the two saddle rails.
Let the saddle frame rails
rest on the lower saddle
clamp plate and hang the
front saddle clamp screw
back in. Loosely tighten
both seat clamp screws.
When tightening the saddle
clamp screws, press the
saddle clamp nuts down
withyourngersothatthey
completely disappear into
the upper saddle clamp
plate.
Attention!The nuts
which are installed
in the top seatclamp
have two small at
areas which have to
be aligned in the long
hole parallel to the
riding direction.
Attention! The screws on the seat post head must not be tightened more than the specied torque of 8Nm. It could
break. This increases the risk of injury.
Loosen the rear fastening screw on the seat post head
with a 5mm Allen key. Adjust the saddle inclination by tur-
ning the front seat clamp screw. After aligning the saddle
inclination with the help of the front and rear saddle
clamping screw, the rear screw must be tightened with a
torque tool with a maximum torque of 8Nm.

Attention! The Postpin axis must be tightened to 8Nm after assembly.
Install the outer sleeve screw
Rotate the outer sleeve so that the mounting hole of the
outer sleeve coincides with the mounting hole on the fra-
me. Screw the M5 mounting screw of the outer sleeve into
the outer sleeve using a 3mm Allen key.
Attention! The screw must be able to be screwed into the outer sleeve easily and without resistance. If this is not the
case, the hole in the frame may not coincide with the mounting hole in the outer sleeve. The frame can be squashed
or damaged
After mounting the saddle, the saddle must be rotated in the direction of riding. It is
best to orient it with the saddle tip on the top tube. Then tighten the Postpin axis with a
torque wrench with 8Nm.

Assembly of the remote lever
The cable system of the Eightpins seatpost consists of a common
cablehousingwithaSteelcoreandashort,moreexiblecable
housing with an Aluminum core directly at the remote lever. The
cable system right at the remote lever consists of a 10 cm Aluminum
cablehousing,aspeciccabletensionadjusetrandaspecicend
cap for the remote lever featuring a reduced outer diameter. The
specicendcapisinstalledattheoneendofthecablehousing,the
cable tension adjuster at the other end. The cable tension adjuster
is installed so that the side with the 4 mm label is connected with the
Aluminum cable housing. The second end is attached to the steel
cable housing that reaches out of the frame.
Note: Initially, put the cable tension adjuster into the minimum cable length position.
Install the remote lever between the grip and the brake lever and tighten its screw with 2.5 Nm.
Note: The lever can be used with 2-speed drivetrain gear levers and without. Make sure the Eight-
pins remote lever does not interfere with the gear lever. Further turn it upwards, in order to avoid this.

releasetheremotelever.Extendingtheseatpostagain,youneedtopushtheremoteleverandwithoutcounterforceletitnditsoriginalheight.The
Eightpins H01 seat post is locked or extended using a hydraulic gas spring. The lowering function works steplessly.
Attention: The remote lever must not be pushed if the bike hangs on the saddle.
Seat post alignment
The Eightpins H01 seat post is equipped with a tolerance compensation system. This enables a rotation of the seat post of ± 3 ° around the
longitudinal axis. If the saddle alignment is rotated around the longitudinal axis, the saddle can be aligned again by loosening the postpin axle and
tightening it again with 8Nm after alignment.

Before every trip
Before each ride, check the following functions on the seat post.
- Freedom of play rotation: The seat post should have only slight play in both directions of rotation. If there is more play, check whether the Postpin
thru axle is screwed tight with 8Nm.
- Clearance of seat post: The seat post tube should only have a maximum of 2-3mm play to the front and rear when tipping. If the play is greater,
check whether the minimum insertion depth has been reached and whether the slide sleeve tube is in order. (See service)
20
EIGHTPINS
- Saddle freedom from play: The saddle frame must always be tight so that the saddle is mounted without play. The rear seat post screw is to be
tightened to 8Nm.
- Smooth running lowering: The seat post must be easy to lower and must also extend easily and smoothly. If this is not guaranteed (friction too
high), the guide must be lubricated via the outer sleeve (see service). If there is no improvement in the lubrication of the seat post, there may be a
setting error in the setting ring in the frame. Broken or squeezed sliding bushes can also be other reasons, or the longitudinal guide on the housing
of the capsule has run dry.
- Remote lever: The remote lever must be easy to operate. Check the free travel of the lever and adjust the cable tensioner if necessary. (See
chapter „Installation of the control lever“) The cable must pull back completely after it has been released so that the lever is tensioned again and the
cable clamp is completely in the holder. If this is not the case, the cable or the outer casing must be replaced (see service)
Note:
After a fall with your bike, or a fall of the bike with possible damage to the seat post tube, the tube must be checked
for damage. Particular attention should be paid to: dents, cracks and chips of the paint. The connection between the
head and the pipe must also be checked.
Pay attention here also to cracks, deformations, etc. and also check the tightness of the screws of the seat clamp.
If you are unsure or have any questions, please contact your local dealer before driving on or starting up.
