The basis is a self-contained hydraulic IFP cartridge with two chambers and internal floating piston. The Jagwire cable, Igus bearings and Trelleborg seals stand for the best quality.

Maintenance Intervals:
The maintenance intervals are dependent on riding style and the geography.
After every ride: Wipe dust and dirt from the seatpost, focusing on the seal area and the tip of the spring. Check the seatpost for any damage.
Every 150-175 hours of driving time: Lubricate the internal components by unscrewing the collar, use spring-specific grease (never oil!) up to the sleeve under the collar and reassemble. Check screw connections for the specified torques.
450+ hours riding time: Check seatpost and replace internal components if necessary.
