The function of the air pressure valve: the soft and hard strength of the shock absorber can be achieved by adjusting the air pressure. The lower the air pressure, the softer the front fork, which is suitable for bumpy roads; the higher the air pressure, the harder the front fork. Suitable for riding on flat roads
