More stroke. No shortening. Quick and easy height adjustment with a large adjustment range.


Why two tubes if one is enough? The Eightpins seat post slides up and down directly in the frame. Technically perfect and visually beautiful.


With the new ISPS, 99% of all bikers can adjust the Eightpins seat post to their body size in two easy steps.


A large pipe diameter provides a lot of stability. Also heavy riders can sit on an Eightpins seat post. Wear and maintenance are minimal.


Less is more

The seat tube of the bicycle frame becomes the immersion tube and housing of the Eightpins seat post. The thick continuous seat post tube fits seamlessly into the design of the bike. The large overlap between seat post and frame as well as the large tube diameter ensure low wear and low operating forces. The Eightpins sliding guide in combination with the outer sleeve for sealing and lubrication ensure long reliable operation. Dirt is effectively prevented and an oil bath lubricates the seat post reliably.

Good bye seat clamp

For 120 years, seat posts were clamped into the bicycle frame. With the Eightpins Postpin axle that has an end. The form locking connection between the frame and the seat post holds the seat post in place and prevents it from twisting. Important components are neither squeezed nor the function is affected.

Ultra-thin guiding

To provide a smooth up and down actuation on the Eightpins seat posts in the frame good sliding elements are required. Special teflon bushings, which are used for suspension forks, are inserted into an ultra-thin aluminum tube. This bushing tube is inserted into the seat post tube from above. This ensures a solid guidance of the seat post tube and transfers the bending forces into the frame.

Reliable lubrication

The seat post tube should always be supplied with a little oil so that it can run as smoothly as possible in the teflon bushings. The outer sleeve of the Eightpins NGS 2 has got major imporvements and was equipped with a large oil reservoir. Two felt rings provide a permanent and dosed oil film that is maintained on the tube.

The perfect seat post with maximum stroke for every body size

Eightpins has further developed the integration standard for seat posts to make it much easier to adapt to the body size. The result is ISPS – Integrated SeatPost Standard. 99% of all bikers can adjust the seat post to their body size in two easy steps without having to shorten or replace the seat post.

A lot of travel turned into more travel The NGS 2 seat post offers up to 258mm travel in the XXL version and the XS version already offers 168mm travel This gives a lot of freedom of movement for difficult downhill sections where the saddle often gets in the way.

For the perfect adjustment of the saddle height, each seat post provides between 102 and 150 mm adjustment band width, depending on the size. The frame of the bike and the seat post grow together. The frames follow one of the two ISPS size schemes depending on the number of frame sizes so that the combination works.

Easy height adjustment

The adjustment of the saddle height in the extended position is done with the patented height adjustment of the NGS 2. By turning the height adjustment actuator in the seat post head the seat post tube is separated from the piston rod and enables a simple and quick adjustment. The new Postpin interface design and the grooves at the seat post end extend the travel oth the Eightpins seat post. In this way, the travel and adjustment range can be expanded enormously.

Automatic travel adjustment

The reduction of the seatpost stroke is a necessary function for telescopic seatposts to be able to adapt to smaller riders. So far this has only worked with the help of additional reduction elements which have had to be installed. The stroke of Eightpins seatposts with ISPS turn automatically to the maximum or reduces itself if the required extension length of the tube is less than the maximum stroke.

No full seatpost exchange anymore

No more compromises in the design of saddle heights and seat post strokes! The Eightpins seat post can easily be adapted to all needs. The seat post no longer needs to be replaced in case of too much or too little travel or overall length at the point of sale or at the customer.

No more cutting

The Eightspins seat post tubes have a specific length for each size. That means the seat post no longer has to be shortened. This makes the Eightpins system the first integrated telescopic seat post system that does not have to be adjusted to the rider’s size by sawing.
