The core characteristics of the front fork air cylinder
High voltage dedicated design
The front fork air cylinder typically supports a high pressure range of 100-300 PSI (7-20 bar), much higher than a regular tire air cylinder (such as about 30-50 PSI for off-road tires).
Double chamber structure (high pressure small volume+low pressure large volume switching) or precision pressure gauge is required to ensure accurate inflation.
Compatible with valve diameter
The front fork air nozzle is mostly American (Schrader) or French (Presta), and some high-end air cylinders can be adapted to two types of valves through a conversion head
