To start your adjustment, turn the knob clockwise until it stops (clicks = 0). Then count 
the clicks while turning the knob counter clockwise.

With a significant hydraulic compression support, the VOID shock allows the bike to 
maintain  a  high  dynamic  balance,  as  well  as  giving  good  response,  and  improved 
handling. BOS recommends setting up the bike with a fast rebound to keep the chassis 
balanced, and avoid the bike sitting low in its travel.  
 
The feeling of «fast» or «slow» rebound will differ from one rider to another. Thus it’s 
difficult  to  define  it  precisely.  We  advise  you  to  define  your  own  range  of  correct 
rebound  -  the  range  of  settings  between  «too  fast»  and  «too  slow».  Then,  always 
choose  a  setting  in  the  faster  part  of  that  range,  for  example  the  three  last  clicks 
(counter clockwise) on a range of nine. 

 

Platform lever (option) 

 
Optionally,  your  SYORS  shock  can  be  equipped  with  a  locking  lever  to  reduce  the  hydraulic  flow  in  the 
compression system. This will be useful during the pedalling period to avoid the work of the shock under the 
effect of pedalling and therefore help to preserve your energy.

 

 

This adjustment carried out by the red lever on shock’s head has two 
positions: Hard / Soft 

 
It is possible to change the place of the lever at your convenience. 
 
In order to achieve this, please respect the following steps: 

 
Loose the locking screw  
 
Remove the lever 2 from the hexagonal nut 3 by 
pulling manually the lever 

 

Position  the  lever  2  in  one  of  the  six  available 
positions on the hexagonal nut  

 

Tight  the  locking  screw  1  with  a  moderate 
tightening torque
