Maintenance method of mountain bike air fork and how to adjust air pressure according to weight

Generally, the maintenance of the air fork of mountain bike should go to the bicycle shop, because the process needs to be more elaborate, and it is not good to damage some parts yourself. Generally, it is not a big problem to pay attention not to enter too much dust, and the weight and air pressure are generally recommended in the front fork. I use the R7 PRO front fork, and the weight and air pressure on it are suggested as follows:

54.4 kg 70-90 psi

63.5 kg 80-95 psi

77. 1 kg 85- 100 psi

90.7 kg

99.9 kg
