Abstract
A suspension fork for a bicycle has a tube system with an inner tube and an outer tube that are movable relative to one another. A damper system with a field-sensitive damping fluid is provided within the tube system. The damper device has a damper chamber that is partitioned to form a first chamber and a second chamber by a movable piston attached to a piston rod. A first throttle valve with a first field generating device and a second throttle valve with a second field generating device enable influencing the first and second throttle valves. First and second switching valves are provided. The first and second throttle valves and the first and second switching valves are interconnected such that in the compression stage there is flow only through the first throttle valve while in the rebound stage the first and second throttle valves are connected in series.
