Shock compression target numbers - Woods thru SX
  • Shock compression target numbers - Woods thru SX                                       vdb / excel / shc_target_numbers.xls
    • Woods at lower end.  MX around aver.  SX at upper end.
    • Pressure testing allows us to break down the fork forces into: comp force, cadj force, drag force and gas force.
    • HOWEVER, for shc target nu series, we only list oall comp force.  The cadj force is based on keeping P.r about 10% above P.ca at 50ips (via Susanto excel).
      • The 1st range is from 2016 WP 50 piston with 4.01 reb bleed area.
      • The 2nd range is from KYB 46 piston with 6.63 reb bleed area.
      • The 3d range is from Showa 50 piston with 3.35 and 4.95 reb bleed area.
        • Use the three charts to get a snapshot of how steep the damping curve is.
