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 different in comparison to other variable seatpo sts. The ad-
justment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 travel 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
Weofferatwo-yearswarrantyforyourseatpostbeginningatthedateofpurchase.Ontopofthis,weoffera10-years
warrantyincaseacomponentsuchasthemaintubeorthebushingbreaks.Thewarrantyexclusivelyincludesthe
repairorexchangeofthe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seat-
post..
Service
As to the service, a major advantage of the Eightpins variable seatpost is that the main tube can be dismounted very
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 hole in the outer label casing.
With the right tools and a basic technical understanding, you may service the seatpost yourself including cleaning and
greasing the bushings, pumping up the system, readjusting the tension of the overload clutch and exchanging the
cable.
Ingeneral,notmuchservicingisrequired.Thelockingmechanismdoesnotwearout.Incasethegaspressurespring
loses pressure, it is to be sent to us or brought to a local service center, as the sealing needs to be exchanged.
Forservicesofallkinds,pleaserefertoyourlocalbikeworkshoporto„Eightpins“LupaanGmbH:
LupaanGmbH
Hafenstrasse47-51
4020Linz
www.eightpins.at
of[email protected]
Attention! Do not service the mechanics or the gas pressure spring yourself as the system is
under high pressure and as one may risk severe injuries.
Safety instructions
Usage as intended
The Eightpins variable seatpost is designed for bicycle frames featuring a Postpin interface. The range of application
includes touring bikes, trekking bikes and mountain bikes. Bicycle frames that do not have this feature should not be
modied..

TheEightpinsvariableseatpostmustonlybeassembledandcombinedwiththeoriginalEightpinsremotelever.Diffe-
rent leverage ratios can cause irreparable damages.
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part-
neratalltimes.Thisistheonlywayacorrectservicecanbeguaranteed.
Modifi cations
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.
Compatibilities
TheintegratedEightpinsvariableseatpostisexclusivelydesignedforframeswitha
Postpininterface.Onecannotretrotthisinterfacetoabicycleframe.Refertoyour
local bike shop in case you are in doubt.
Attention: Eightpins decisively advices its customers not to modify a frame in any way, as this
can weaken the frame, cause crashes and lead to severe injuries including death.
Seatpost travel and insert lengths (do not mix up!)
Attention! do not mix up!
Eightpinsvariableseatpostscomewithaframespecicmechaniccapsuleandbushingswithdifferentmeasurements
asrequiredbythemanufacturers.Thelengthofthebushingtubeisthesameastheactualinsertlengthsinceittrans-
fers the lateral forces into the frame.
Attention! One may exclusively use compatible seatpost diameters, variable seatpost travels
and bushing tube lengths as stated by the manufacturers.
Theseatposttubecomeswith480mmasstandardandneedstobecutwhenadjustedtotheriders’size.Whenthe

Using the seatpost
Inordertolowertheseatpost,pushtheremoteleveratthehandlebarandpushdowntheseatpost.Inordertokeep
thenewsaddleposition,releasetheremotelever.Extendingtheseatpostagain,youneedtopushtheremotelever
andwithoutcounterforceletitnditsoriginalheight.TheEightpinsvariableseatpostworksfullymechanicallyand
features click notches every 6 mm.
Attention: The remote lever must not be pushed if the bike hangs on the saddle.
Aligning the seatpost / Operating the overload clutch
TheEightpinsseatpostfeaturesanoverloadrotationclutch.Thisallowsfortheseatposttoturnawayincaseofa
crash and thus prevents both the saddle and the seatpost from damages. If this has happened, the saddle can simply
bebroughtbackintoplacebyturningit.Ifthebreakawayforceistoolow,itcanbeincreased(refertothechapter
“Service”).
Attention: the saddle can be turned to the left or right with a maximum angle of 90°. If it is turned
further, it will be damaged severely.!
Seat height adjustment top position
Refertothechapter“Seatheightadjustment”.
Adjustment of the saddle angle
Refertothechapter“Installationofthesaddle”.
Before every single ride
Checkthefollowingfunctionsoftheseatpostbeforeeveryride:
- In both rotation directions, there should be no play noticeable.
- The seatpost should not have more play than 2 – 3 mm to the front or back. If the clearance is bigger, check the mini-
muminsertlengthandwhetherthebushingtubeisok(alsorefertothechapter“Service”).
-Thesaddlemustnothaveanyplay,thebackscrewistobetightenedwith8Nm
-Themechanicstolowertheseatpostistorunsmoothlyandwithoutfriction.Incaseyounoticefriction,thebushing
tube is to be greased.
-Theremoteleveristorunsmoothly.Thetensioncableshouldbeadjustedcorrectlywhichyoucandowiththecable
tensionadjuster(refertothechapter:“Cablerouting”).Theleverautomaticallyistogobackintoplacewhenreleased.
If this is not the case, you presumably need to replace the cable.
- Check the function of the click mechanism in the top position, in the bottom position and in an intermediate positions.
If you hear a grinding noise, the cable tension needs to be controlled.

not damage the bushing tube. Remove unnecessary grease.
3 If necessary, pull the cable housing out of the frame again..
4 + 5 Slip the outer sleeve over the frame being aligned with the hole drilled before.
6.-8. Take the wiper upside down and insert the bended felt stripe in the inner diameter of the wiper bottom.
9. Insert the white wiper ring in the outer sleeve.
10.+11. Press the wiper into the outer label casing; you might face some resistance.
12. With a 5 mm Allen key, carefully screw the plastic screw into the seat tube.
13. With a torque wrench, tighten this screw with 0.5 Nm.
Assembly of the seatpost
Beforeassemblingtheseatpost,unwrapthepreinstalledcable.
1 The Aluminum end cap (big) needs to be slipped over the cable housing that reaches out of the frame.
2 + 3 Insert the cable into the cable housing until it reaches out of it again at the top of the frame.
4HangthecablehousingonthecablehousingcounterpartatthePostpinmountingunitatthelowerendoftheEight-
pins capsule.
Attention: The seatpost needs to be aligned in a way that the top of the seatpost as well as the
cable points towards the back of the bike.

ATTENTION: 9. 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.
Note: Altering the saddle angle, you always need to loosen the rear screw rst.
ATTENTION: If the nut are not aligned correctly and the screws get tightened, the nuts get
damaged and can´t move anymore. This can cause a crack of the screws. High risk of injury!

Adjusting the seat height
Explanation for the adjustment of the seat height:
Inordertohavetheseatheightinthepositionwantedwhentheseatpostisfullyextended,ithastobeadjusted
correctly.Asthedesigndoesnolongerincludeaquickrelease,theprocedureissomewhatdifferentfromcommon
systems.TheEightpinsvariableseatpostincludesahigh-pressuregasspring,whichgeneratestheforcetopushthe
seatpostupwards.Thisforceistransferredviaapistonrodandaconnectionelement(seatheightadjustmentclamp)
totheactualseatposttube.Theseatheightadjustmentclamp–turningitclockwise–canbeconnectedtotheseat-
postatdifferentheightpositions.Dependingonthepositionchosen,theseatpostwillalwaysextendagaintoit,afterit
hadbeenlowered.Theseatheightadjustmentclampcanbeoperatedorturnedfromtheoutsideviatheseatpost
height adjuster (Picture 1 and 2) that can be found inside the top of the seatpost. For this, one does not need anything
buta2.5mmAllenkey,withwhichyoumayturntheseatheightadjusterina45°angletoopenorcloseit.3Whenthe
seatheightadjustmentclampisopen,theseatheight–operatingtheremotelever–canbeadjustedwithoutaffecting
thehigh-pressuregasspring.Thisway,theentireseatpostcanberemoved,also.Theactualseatheightisadjusted
whentheseatheightadjustmentclampisopenandtheremoteleveratthehandlebarispushedsimultaneously.
Releasetheremoteleverandhavetheseatpostclickintoplacewhereyouwantit.Closetheseatheightadjustment
clampagainbyturningthe2.5mmAllenkeyclockwisefor45°.
.
Attention! It is important to have the seat height adjustment clamp closed at all times when ri-
ding your bike. In case the mechanics are jammed, move the seatpost tube up- and downwards
slightly and simultaneously turn the seat height adjustment clamp clockwise.

Adjusting the seat height
4Goforarsttestrideandadjusttheseatheightwiththeremotelever5-10Iftherightseatheightisreachableleave
thesaddleheightinthechosenposition.Thenturntheheightadjuster45°witha2.5mmallenkeycounterclockwise.
Youwillnoticeaslightclicknoisewhenthepistonrodinsidetheseatpostndsbackintoplace.Thenturntheheight
adjuster45°clockwisetolocktheheightadjustmentsystemagain.5-10Ifthehighestpositionistoolowduringthe
testride,turntheheightadjuster45°counterclockwisewitha2.5mmallenkey.11Pushtheremoteleverandpullthe
seatposttubeoutfurther.12Afterthisprocess,makesuretheseatposttuberemainsinbothbushingstube,which
means that it still sits in them. If the sesatpost is not guided in both bushings it has a lot of play. 5-10 The moment the
seatheightisinthepositionyouwantittobein,turntheheightadjuster45°clockwisewitha2.5mmallenkeytolock
the height adjustment system again. The seat height has been adjusted.
The concept of shortening the seatpost tube
With the goal to have the maximum travel of your Eightpins variable seatpost for your individual seat height, the seat-
postneedstobeshortened.Iftheseatpostistoolong,itwillnothaveenoughspaceinsidetheframeforthefulltravel
whenlowered.Beforeshorteningtheseatpost,theidealseatheightistobeevaluated.Thereferencepointforthe
followingmeasurementisthetopendofthewiper.Aftertheshortening,theseatpoststillneedstobelongenoughto
beguidedbythetwobushings.Thetwobushingsareguidedinthebushingtube.Thistubeisavailablewithdifferent
lengthsdependingontheframesizeandtheindividualinsertlength.Thedistancebetweenthetwobushingtubes
equalstheinsertlengthoftheseatpostintheframeanddependsontheframe.Thetubeneedstobelongenoughin
ordertoguaranteefortheminimuminsertlengthwhentheseatpostisfullyextended.Ifthetubeistooshort,andifit
isthusnotguidedbythetwobushings,theframeortheseatpostcanbedamaged.Thestencilisdesignedinawayto
leave some tolerance of the seat height if you change your pedals, your shoes or your saddle..

Attention! The seatpost tube needs to be
guided by both bushings. This means that-
the minimum insert length is to be minded
as you risk damaging your frame or inju-
ringyourself.

Stencil for shortening the seatpost
Theseatpostcomeswithastencilforshorteningitcorrectly.ThesizesXStoXLrefertothedifferentframesizes.The
referencepointforthemeasurementandthereforethepointtoattachthestenciltoisthetopendofthewiper.After
theadjustment,markthepositionwithsometape,removetheseatpostandpositionthestencilatthebottomlineof
thetape–downwards.
Thestencildisplaysagreenandaredscaleineverycolumn,dependingontheframesize.Ifthetubeiscutinthe
greenarea,thefulltraveloftheseatpostwillbeavailable.Ifitiscutintheredarea,thetravelneedstobereduced
withtravelreductionspacersinordertoavoidacollisionoftheseattubewiththePostpinxationinsidetheframe
(picture1).Ifthetravelshallbereduced,refertotheredarea.Ifthetubereachesintoanewboxonthescaleonly
slightly, refer to this box and mount reduction spacers respectively. For further information, also read the chapter
“Reductionthetraveloftheseatpost”.
4. Cuttingthetubeatthelowerendofthegreenarea:theseatheightcanbeincreasedafterwardsmorethaninpoint
