Fork compression target numbers
  • Fork compression target numbers - Woods thru SX        
    • Woods at lower end.  MX around aver.  SX at upper end.
    • Pressure testing allows us to break down the fork forces into: bv force, mv force, drag force and gas force.  This 'fkc target nu' chart helps up determine.
      • how much is bv
      • how much is mv
      • how much beginning force
      • how much ending force
      • where do they cross
