Abstract: A suspension system for a bicycle includes a first body defining a hollow interior, a second body configured to slide linearly within the hollow interior along an axis, and a rod disposed partially within the hollow interior and engaged with the second body. The rod extends along the axis. The suspension system also includes a sensor disposed outside of the hollow interior. Linear movement of the second body within the hollow interior along the axis is configured to create rotational movement of the rod about the axis, and the sensor is configured to detect the rotational movement to determine a linear displacement of the second body.
