How to Fill Air Shocks

Mountain bike suspension systems often use air shocks for either the front fork, rear shock, or both. Air shocks operate with air in a sealed chamber that compresses or expands, depending on pressure from hits and jumps placed on the system. To get the air shocks working properly, air must be added into the chambers. Special air shock pumps are used to get the recommended pressure into the chamber.
