A suspension assembly for a bicycle, comprising: a primary tube (302); a piston rod (310) supporting a piston (308) and being capable of motion relative to said primary tube (302), said piston (308) and said primary tube (302) at least partially defining a first fluid chamber (314), wherein one of said primary tube (302) and said piston rod (310) is configured to be connected to a wheel portion (103) of a bicycle and the other of said primary tube (302) and said piston rod (310) is configured to be connected to a frame portion (120) of a bicycle; a secondary tube (304) at least partially defining a second fluid chamber (332), wherein said first fluid chamber (314) and said second fluid chamber (332) are filled with a liquid and wherein liquid flows between said first fluid chamber (314) and said second fluid chamber (332) in response to relative motion of said piston rod (310) and said primary tube (302); an inertial valve (322) having a first position and a second position, said inertial valve (322) blocking a flow of liquid from said first fluid chamber (314) to said second fluid chamber (332) in said first position and thereby preventing any significant relative motion of said primary tube (302) and said piston rod (310), said inertial valve (322) permitting a flow of liquid from said first fluid chamber (314) to said second fluid chamber (332) in said second position and thereby permitting relative movement of said primary tube (302) and said piston rod (310). <IMAGE> |
