[Part and Quantity] Front Shocks (2) [Part Number] DR70-114 [Materials] Metal tubing with a metal piston. The air chamber inside the tubing is pressurized. [Forces] Forces caused by vibration and sudden changes in height. Shocks absorb forces because of weight from bike and rider. [Manufacturing Process] Two cylindrical tubes connect to each other with the smaller one being underneath the larger one. This allows for the smaller tube to fit inside the larger tube where forces are eliminated with the use of an air pocket. [Shape] Cross sectional area and dimensions of the air chamber depend on the desired force to negate. [Part Complexity] 4 [Function] 
Functional: Absorbs vibration from the front wheel to provide a smooth ride for the rider.
