General
ThankyouforequippingyourbikewithanEightpinsvariableseatpost,ahighstandardized,highlytechnicalproductfor
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-
justmentoftheseatheightaswellastheadjustmentofthetraveloftheseatpostisrealizedwithonesingletube.The
mechanicsforthisisdirectlyconnectedwiththeframeviathePostpinaxlethatabsorbsallaxialforces.Thelateral
forces are absorbed by the bushing tubes and thus by the frame. It is therefore crucial to mind the maximal travel as
wellastheminimuminsertlength.
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.

Service
As to the service, a major advantage of the Eightpins variable seatpost is that the main tube can be dismounted very
easilyandthattheanti-frictionbushingcanbecleanedand/orexchangedquickly.Incaseyounoticeahigherfriction
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.
Ingeneral,notmuchservicingisrequired.Thelockingmechanismdoesnotwearout.Incasethegaspressurespring
loses pressure, it is to be sent to us or brought to a local service center, as the sealing needs to be exchanged.

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.

Attention: the saddle can be turned to the left or right with a maximum angle of 90°. If it is turned

Refertothechapter“Seatheightadjustment”.
Adjustment of the saddle angle
Refertothechapter“Installationofthesaddle”.
Before every single ride
Checkthefollowingfunctionsoftheseatpostbeforeeveryride:
- 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-
muminsertlengthandwhetherthebushingtubeisok(alsorefertothechapter“Service”).
