The  S  position

  is  for  comfort.  

  

The  H  position

  is  used  for  pedaling  efficiency.  

The  H  position  considerably  stiffens  the  fork  in  an  effort  to  limit  suspension  oscillations  during  pedaling,  but  without  locking  out  
the  fork  completely.  Thus,  BOS  remains  faithful  to  the  principle  of  keeping  an  active  fork,  even  in  its  restrained  state.  This  allows  
for  the  suspension  to  move  over  unexpected  bumps,  which  is  a  simple  matter  of  security.    

  

The  M  position  

maintains  hydraulic  control  and  grip.  

The  M  position  in  the  middle  is  set  at  a  precise  position  at  the  factory.  However,  the  final  user   maintains  the  possibility  

of  adjusting  the  firmness  between  the  S  and  H  poles.  In  effect,  M  is  the  base  position  that  offers  the  best  compromise  between  
comfort,  chassis  support,  and  grip.  If  the  rider  prefers  a  softer  feeling  or  a  harder  feeling,  he  may  change  the  position  toward  the  
open  or  closed  positions,  S  and  H,  without  affecting  the  tuning  of  the  fork.
