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

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.

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

5mins bleed via external 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.

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.

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.
