How to deflate the pneumatic shock absorber of mountain bike?

The correct way to deflate the pneumatic shock absorber of mountain bike is:

1. Open the protective cover of the air nozzle of the shock absorber to expose the air nozzle;

2. Connect the gas nozzle with a special inflator with a barometer;

3. Inflate the shock absorber with a pump to make the air pressure close to the normal pressure of the shock absorber;

4. Gently loosen the deflation screw on the air pump, observe the barometer, and stop deflation after reaching the required air pressure. (In general, the minimum air pressure cannot be lower than 80% of the standard air pressure)

5. Remove the air pump, cover the air nozzle protective cover, and run normally.

Extended data

Shock absorbers are generally mountain bikes, and road cars are not equipped with shock absorbers.

Shock absorption can be divided into spring, resistance glue, air pressure and oil pressure.

Air pressure is to use the pressure of sealing gas to achieve shock absorption. Advantages: light (because the source of resistance is gas, please know how heavy the gas is), not afraid of aging. The disadvantage is the air pressure, even the best seal will leak, so it is necessary to test and adjust the air pressure frequently, otherwise it may damage the fork body because of the unbalanced air pressure. (For example, ROCKSHOX's SID series is semi-pneumatic and semi-hydraulic).
