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. - Page 4 The various work steps can be found in the Service chapter. For services of all kinds, please refer to your local bike workshop or to Lupaan GmbH: Lupaan GmbH „EIGHTPINS“ Kristein 2 4470 Enns www.eightpins.at service@eightpins.at...

Page 5: Safety Instructions
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. -
Page 6: Ergonomic Aspects
EIGHTPINS The product may only be used by a person who has no physical restrictions and is familiar with the operating instructions. The use of the product is only permitted by a person sitting on the bike. Ergonomic aspects: The ergonomics point was considered taking DIN EN ISO 12100: 2011 into account. Since the telescopic seat post offered by Eightpins is only part of the bicycle, ergonomic considerations cannot be considered. -

-Sonic Evo Carbon -4-One Gravel MK1 -301CE MK1 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. Eightpin‘s seatposts are divided into two different size schemes. There is a size scheme with 4 sizes: S, M, L and XL and a size scheme with 6 sizes: XS, S, M, L, XL, XXL. The size to use depends entirely on the frame size. - Page 9 EIGHTPINS...

Page 10: Installation
EIGHTPINS Installation Frame/Seattube The frame must have a 5mm hole at the top of the seat tube to mount and fix the outer sleeve. If this hole does not exist, refer to the manual of the frame supplier to find out how to drill this hole in the seat tube of the frame. 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. -
Page 11: Installing The Bowden End Cap
EIGHTPINS Installing the bowden end cap A special end cap is required to fix the outer cover to the wide mounting interface of the H01 seat post. The special end cap is only required in bicycles without e-drive (left image). Bicycles with electric drive have little space between the motor and seat post for the exit of the cable. A special flexchain outer cable is used here (right picture). This is installed between the outer shell and the special end cap. Installing the seatpost Before installing the seat post, check whether the small tube and the washers for tole- rance compensation of the seat post are installed. - Page 12 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 Push the outer sleeve and the bushing tube down for easier assembly.

Page 15: Assembly Of The Remote Lever
EIGHTPINS Assembly of the remote lever The cable system of the Eightpins seatpost consists of a common cable housing with a Steel core and a short, more flexible cable housing with an Aluminum core directly at the remote lever. The cable system right at the remote lever consists of a 10 cm Aluminum cable housing, a specifi c cable tension adjusetr and a specific end cap for the remote lever featuring a reduced outer diameter. - Page 16 EIGHTPINS If the cable housing can be pushed into the frame in any way during the check, it has been detached from the cable housing counterpart at the Postpin mounting interface.

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. - Page 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).

Page 21: Operation
Operation Adjusting the saddle height The Eightpins H01 seat post has a height adjustment operating lever in the seat post head. This unlocks and locks the internal height adjustment of the seat post. Before the correct height of the saddle can be set, the internal hydraulic gas spring of the seat post must be fully extended. -

Unscrew the four fastening screws of the longitudinal guide shoes with a 2mm Allen key. - Page 30 EIGHTPINS Clean the longitudinal guiding blocks and the cartridge unit if necessary. Clean the screws from adhesive residues of the screw lock. Place the longitudinal guiding blocks at the end of the longitudinal guides. The cartridge must be oriented in such a way that the cable housing holder is oriented towards the front in the direction of riding, while the seat post head must be oriented towards the rear against the direction of riding.
- Page 31 EIGHTPINS Insert the cartridge unit into the seat post tube until the holes align with the screw holes of the longitudinal guide blocks. Drip high-strength screw lock on the four mounting screws for the longitudinal guiding blocks and screw them in carefully. It is best to first align one side and then by pushing in or pulling out the cartridge unit, align the longitudinal guide shoe on the other side with the holes and screw tight.

Make sure that the longitudinal guides of the cartridge are not in engagement with the open-end wrench and are therefore not damaged. Due to the fine thread, a relatively large number of turns are necessary to completely unscrew the brass guide.
- Page 34 EIGHTPINS When both screws are loosened, the hydraulic gas spring can be pulled out of the cartridge. At the end of the piston rod are the mounting adapter and the actu- ating plunger of the hydraulic gas spring. Pull out the compression spring and place it aside.
- Page 35 EIGHTPINS Before installing the new gas pressure spring, the position of the moun- ting adapter must be checked and readjusted if necessary. The holes in the mounting adapter must be aligned with the holes on the torque brass ring. To do this, align the mounting adapter with the holes.
- Page 36 EIGHTPINS The holes in the piston rod adapter must coincide with the mounting holes in the mounting interface. You can control this from the outside by looking into the holes. Due to the spring preload, the holes can only really cover when you push the gas pressure spring into the cartridge with a little force.

Die obe Carefully screw the brass guide into the tube of the cartridge. If it is diffi- cult to move, use the 23mm open-ended wrench for support. The two lugs of the upper brass guide must be aligned with the longitudi- nal guide grooves on the tube of the cartridge.
