Cable routing options:


ccs-62657-0-45771300-1465301406.jpeg

Internal
The cable end connects at the bottom of the seatpost to ease installation and post removal.

External
The cable housing stop can be reoriented approximately 60 degrees forward or rearward from the original inline position to allow for the smoothest possible routing.


Installation and setup are made easy with tool-free cable disconnect and this Setup Guide.

  • Spool Valve design offers great modulation, making it easy to regulate return speed and control small height adjustments
  • All hydraulic internals are housed in the upper post, creating a lighter, more integrated design
  • Larger diameter hydraulic system translates to lower internal pressures, providing better durability and lighter actuation force at the lever
  • Other brands use cartridge designs with smaller internals
  • Mechanical linkage of the Actuation Assembly further decreases lever force


External Post

  • Benefits from same hydraulic and lever design features as Internal post
  • Fixed External Actuation Pulley on lower post


Spool Valve

  • Hydraulic design features large diameter Piston and Spool Valve to regulate seatpost movement
  • Larger Piston design lessens the force required at the lever and improves durability
  • Spool Valve integrates a Pressure Relief Valve for an extremely durable design

Spool Valve Closed: Glide Bands on Spool Valve block oil from moving through flow ports.

Spool Valve Open: Spool Valve and Glide Bands move up, allowing oil to move through flow ports. Oil can flow in either direction when open.


Pressure Relief Valve

  • Automatically relieves large pressure variances across Piston
  • Eliminates pressure spikes and adjusts for thermal expansion in the system
  • Maintains consistent action during heavy use, cold riding temperatures and extreme elevation changes
  • Extremely durable design

When pressure above the Piston is much greater than pressure below the piston, the Pressure Relief Valve will open. Oil will flow through a small port in the Spool Valve to balance the system.
