Abstract
A bicycle suspension system is provided with a first tubular element, a piston, a piston rod, a first sealing member and a switching valve. The piston is coupled to the piston rod, and is slidably disposed in the first tubular element. The first sealing member is disposed in the first tubular element adjacent such that a first air chamber is formed between the piston and the first sealing member. The switching valve is coupled to the first sealing member. The switching valve opens a communication passageway between the first air chamber and a second air chamber to connect the first and second air chambers when in the opened position, and closes the communication passageway between the first air chamber and the second air chamber to separate the first and second air chambers when in the closed position.
