FAQ - Suspension Part I

More Info Regarding the Cartridge Emulators

Q:  I have several questions regarding the cartridge emulator’s that I just received for my bike.

  • Must I drill the mentioned holes in the damping rod? If yes, must I drill the additional 4 holes to 5/16" or 1/4" (what is it in cm?)?
  • And there are two additional little springs (colored blue), which one must I use?
  • In the attached springs, what is the function of the two o-rings?
  • Which fork oil should I use (original 10 weight)?
  • What oil-level should I set?

 

A:  Here are the answers to your questions.

  • Yes, your must drill the holes or the emulators will not work properly. 1/4" - 5/16" = 7-8 mm.
  • The extra springs are for further tuning, in case the springs that are installed are not stiff enough. You probably won't need them.
  • The o-rings are spares in case you ever have to disassemble the valve bodies. You probably won't ever need them either.
  • Use 10 weight oil
  • We like 165mm (6.5") from the top with no springs and the fork completely collapsed as a starting point for the oil level. This oil level can be changed to tune the bottoming resistance of the fork. More oil makes it more progressive and resists bottoming at the end of the stroke. Less oil will make the fork action feel more linear.
