New and unique hydraulic system, to bring the maintenance to the minimum. Full system bleed can be performed in a matter of minutes, without taking the seatpost off the bike. No special tools needed.


New, patented Constant Force Valve, oversized air chamber and completely redesigned bushings provide even smoother action and quicker actuation that remains fully under control of your finger on the remote throughout the travel.


Our components are Swiss Made, built in a small workshop with a lot of care and attention to detail. Therefore we can vouch for our product and stand behind it. You can find service tutorials here on our website.

the new YEP Uptimizer 3.0 seatpost comes packed with entirely new features and patented solutions.


new patented
NGC cartridge

This no-gas cartridge allows you to overhaul the hydraulic system easily and without the risk of the cartridge blowing off.


bleed port

Bleed the system without having to perform the full service or even without taking the seatpost off the bike! Experiment with oil weights to adjust your seatpost’s action to your needs.


air chamber

Allows pressure to ramp up in a linear way. Actuation is effortless compared to other systems on the market.


new patented
CF Valve

Our newly developed Constant Force Valve controls oil flow regardless of the internal air pressure to provide a very sensitive remote action and instant actuation.



Now you can reduce the travel of your seatpost and the total length with simple add-on spacers. 5, 10 and 15mm spacers are supplied with the seatpost.


air chamber

Adding tokens will decrease the air chamber volume. This will change the feel when you compress the seatpost. There will be more resistance from the saddle and more force will be required to push the saddle down.Available separately.



The joystick remote can be installed left, right, up or down on handlenbars. It can be actuated with the thumb or the index finger. Works with both ends of the gear cable. Simple and solid construction makes it truly crash resistant.
