THE SPRING HARDWARE
If the fork has a platform system for bob suppression,
switch it off first (reduce the Manitou pressure in the SPV chamber to 2.75 bar). Loosely attach a cable tie to one of the stanchions and slide it downwards. Sit carefully on the bike and assume the riding position (support yourself with your elbow on the wall). Now dismount and grab the measuring tape.
The negative suspension travel (Sag) is the distance from the lower edge of the cable tie to the upper edge of the dip tube seal. The negative suspension travel should account for around 15 per cent of the maximum stroke for marathon use. The rougher the terrain, the more important the negative travel becomes. For all-mountain bikes, we recommend 25 per cent. Now adjust the pressure in the main chamber until the sag is correct. For forks with a separate negative air chamber, refer to the manual for the appropriate positive air pressure. Then set the negative air pressure as explained above.
THE TRAIN LEVEL
This feature regulates the rebound speed of the front wheel after an obstacle. First turn the rebound and compression damping towards "undamped" and leave the platform switched off. Now close the rebound damping so that the fork no longer springs back after impulsive compression when stationary, but comes up just visibly slower. Try out this basic setting with slightly different settings on the home circuit. Caution: Too much rebound prevents the fork from following fast bumps.
If the fork emerges with a slight delay, the basic setting is correct.
