Low speed compression is adjusted using the gray dial located at the top of 
the right plunger (2-A). Allows the fork's harshness to be adjusted during small 
impacts by regulating the hydraulic flow 

 

High speed compression is adjusted via the black dial located at the top of 
the right plunger (2-B). Allows to adjust the harshness of the fork during big 
shocks by regulating the hydraulic flow. 

 

The traction control is adjusted using the red lever (2-C). By acting on this 
lever, the upstream oil flow is adjusted, before it can shift into high and low 
speed compressions. Its effect is to stiffen all speeds as it reduces oil flow, 
without going so far as to block. This results in better support and therefore 
increased efficiency.

 

 

 

To  start  setting  your suspension  adjustment,  turn  the  knob  all  the  way  in  the  clockwise 
direction (=click 0) then turn your adjuster counterclockwise one click at a time. 

 

 

Tuning tips: 

When it comes to hydraulic settings, there is no such thing as a “magical formula”; many factors have to be 
taken into  account  (bike  balance,  bike geometry, and rider preferences to name a few). Having  that  said, 
the following may help guide your adjustments: 
 

 

Excessive diving of the fork under braking : harden the traction control 

 

Frequent bottom-out : harden compression 

 

Feeling of harshness on roots and rocks (square edges) : soften compression 

 

Discomfort, arms getting sore : soften compression, and/or traction control 

 

Fork stays low over successive impacts and doesn’t spring back : speed up rebound 

 

Bike sits too high in travel : slow down rebound 

 
 

Whenever you are far from the standard settings (Starting point settings), it’s always good to consider what 
influences the  performance of the fork. Proceed step by step, one setting at a time by hardening or softening 
just a few clicks each time. 
If you ever get lost while you are setting up the forks, always go back to the starting point settings.
