DebonAir TM Air Cans only: Use a shock pump to pressurize the shock to the desired air pressure. After adding air to the shock, thepressure will need to be equalized between the shock chambers.Record the air pressure value on the pump, then unthread it from the shock. Slowly but firmly press or sit on the saddle tocompress the shock until there is a hissing sound.This sound indicates air transfer between chambers. Record the air pressure, then unthread it from the shock. Repeat this processuntil you reach the desired amount of sag.
